Tools and Services
A detailed guide to what each tool examines, what you need to provide, how the processing works, what the result contains, and where the technology stops.
TrichoLens is designed for personal awareness, structured tracking, and better-informed conversations with healthcare professionals. It is not a diagnostic tool and does not replace medical or dental advice.
How to read this guide
What every result means
Evidence paths vary by tool
When a workflow produces overlays, per-photo findings, settings, or confidence notes, those details remain visible for review. Other tools rely on user-entered ratings or structured records.
Consistency matters
Lighting, angle, focus, crop, camera distance, magnification, and styling can change what a photo appears to show.
Your account, your controls
Plan-based storage is scoped to the signed-in user, with export and deletion controls available in account settings.
Visible pattern and condition screening
These tools examine ordinary or close-up photographs for visible patterns. They organize what can be seen in an image, but they cannot determine a biological cause or make a diagnosis.
Quick Checkup
BetaA fast entry point for hair or scalp images. The user chooses a broad head-view or close scalp-view path, and an image classifier checks whether the selected mode matches the upload.
- Plan access
- Available across plans with plan-specific daily limits
- Capture requirement
- Phone photo or scalp-camera image
Best suited for
A first look when you have one image and want to know which visible features deserve closer tracking.
What you provide
One JPEG, PNG, WebP, or supported phone image. A centered full-head photo supports pattern screening, while a sharp close-up supports scalp and follicle observations.
What the result contains
- A concise visual assessment with the most relevant visible findings
- Pattern or scalp observations appropriate to the detected photo type
- Image-quality notes, confidence context, urgency language, and a screening disclaimer
Important limitations
One photograph is a snapshot. Styling, wet hair, flash, camera distance, and an unusual angle can change the apparent density or scalp visibility. A quick result should be treated as a prompt for consistent follow-up, not as proof of change.
Technical processing details
- The request performs image validation and safety checks before analysis. A classifier checks macro versus general framing and can recommend switching modes so a close scalp image is not interpreted as if it were a full hairline view.
- A structured vision response separates visible observations, image-quality concerns, pattern estimates, confidence, and follow-up guidance. The result is normalized before it reaches the interface so missing or malformed fields do not become invented measurements.
Storage and control
History saving and retention depend on the active plan. The interface identifies results that are available only for the current session.
Scalp Scan
BetaAnalyzes one or more scalp photographs for visible hair-loss pattern, scalp condition, hairline and crown observations, and review priority.
- Plan access
- Available across plans with different photo and history limits
- Capture requirement
- Phone or scalp camera
Best suited for
A structured screening report from a hairline, crown, part-line, or close scalp image, especially when several angles need one combined review.
What you provide
Up to the number of photographs allowed by the plan, plus optional age and sex context used to calibrate pattern-scale language. Even lighting and a sharp view of the region of interest matter more than raw megapixel count.
What the result contains
- Per-photo findings with angle, pattern, priority, and confidence context
- An overall review that explains where multiple views agree or disagree
- Follow-up chat grounded in the current scan results when plan access allows it
Important limitations
Apparent scalp exposure is not a calibrated hair count. Age and sex can improve scale selection, but they do not turn a photo into a clinical examination. Inflammation, scarring, infection, and sudden shedding require professional assessment.
Technical processing details
- Each image is analyzed independently so the report can preserve which observation came from which angle. A synthesis step then compares agreements and conflicts across the images instead of averaging every view into one opaque answer.
- Preflight checks estimate brightness and sharpness. The result schema includes visible pattern, stage language where appropriate, hairline and crown notes, urgency, confidence, red flags, and recommendations.
Storage and control
Saved scans are associated with the user account when the plan supports history. Session-only results are labelled before the user leaves the page.
Spot Analysis
AvailableFinds bright or visually distinct connected regions in a scalp image and quantifies how much of the selected frame they occupy.
- Plan access
- Plan limits apply to analysis, saved results, and AI follow-up
- Capture requirement
- Phone or scalp camera, close-up preferred
Best suited for
Exploring reflective areas, visible scalp, flakes, sebum-like shine, or other high-contrast regions while retaining manual control over sensitivity.
What you provide
A focused scalp image or a cropped region of interest. The user can adjust the brightness threshold and minimum connected-blob size to match the capture.
What the result contains
- Detected-region count and percentage coverage
- A toggleable overlay that shows exactly which pixels contributed to the calculation
- Sensitivity settings, crop controls, saved result cards, and optional AI interpretation
Important limitations
Brightness is not a diagnosis. Flash glare, pale hair, exposed scalp, white flakes, and reflective product can all cross the same threshold. Comparisons are most meaningful when the crop, lighting, and settings are repeated.
Technical processing details
- The browser converts pixels to luminance, marks candidates above the selected threshold, and groups adjacent pixels with connected-component analysis. Components below the minimum size are removed as noise.
- The tool counts retained regions and derives its displayed coverage metric from the selected pixels and analyzed area. The overlay is therefore a reproducible image-processing result, while the AI summary is a separate interpretive layer.
Storage and control
The original or cropped image, numeric settings, and result can be saved to the user history subject to plan limits.
Shape of Loss
BetaBuilds a personalized spatial map from four guided head views, then projects visible hair and scalp evidence onto a continuous anatomical surface.
- Plan access
- Basic and Pro
- Capture requirement
- Four phone photos: front, left, right, and top
Best suited for
Understanding where visible coverage is concentrated and comparing the shape of coverage across repeated four-view scans.
What you provide
A complete front, left profile, right profile, and top view with the full head visible. Consistent lighting, plain contrast around the outline, and matching capture distance improve the fit.
What the result contains
- Interactive realistic and loss-intensity views of the fitted surface
- Derived stage, affected-area estimate, confidence, regional distribution, and rationale
- Side-by-side, difference-map, and timeline comparison after two or more saved scans
Important limitations
This is not photogrammetry and does not recover hidden anatomy. Rear geometry and fine facial relief are inferred. Hair viability, scarring, and cause cannot be established from the surface map, and a patterned background can reduce silhouette quality.
Technical processing details
- The browser isolates measured head silhouettes, trims attached shoulders, segments visible hair and scalp, and normalizes all four views. Those silhouettes constrain an anatomical head surface rather than selecting a generic preset.
- View-facing projection maps photographed color and coverage only onto surface regions seen by each camera. A normalized coverage field supports regional metrics, pattern-template comparison, and a derived Norwood estimate. Optional worker reconstruction can add a denser point surface without blocking the main analysis.
- Saved scans use a bounded coverage grid and packed binary silhouettes so comparisons can calculate regional and net change without resending the original analysis request.
Storage and control
Saved records can include the four source photos, normalized coverage, metrics, and compact silhouettes. Save limits are enforced per plan.
Self Assessment
AvailableUses an uploaded photo as a visual reference while the user records repeatable condition categories, severity ratings, and notes.
- Plan access
- Available to signed-in users; saved assessments do not currently use a plan-specific history cap
- Capture requirement
- At least one phone or scalp-camera photo is required to begin
Best suited for
Recording symptoms and visible changes such as oiliness, dryness, flaking, sensitivity, inflammation, or a changing hair-loss pattern.
What you provide
One or more reference photos to enter the workflow, selected condition categories, a severity level for each category, optional notes, and the assessment date.
What the result contains
- A 0 to 100 self-reported scalp-health score with category breakdown
- Saved notes, severity labels, assessment date, and previous assessment reports
- An optional explanation of what the selected pattern may be worth discussing with a professional
Important limitations
The score measures the entered ratings, not the pixels or disease activity. Two people can rate the same image differently. Saved assessment documents do not currently retain a direct association to the reference photo.
Technical processing details
- The tool applies a transparent weighted score to the user-selected severity levels. Minimal ratings carry no penalty, and increasing severity lowers the composite score in a predictable way.
- Optional AI chat receives the structured ratings and, on the first message, a small version of the active session image when available. It can organize questions and next steps, but it does not replace the user-entered ratings.
Storage and control
Assessment ratings and notes can be saved to the account and deleted from the assessment history. A photo uploaded from the device may also be added to the separate gallery flow.
Mouth Scan
BetaProvides general oral screening plus focused modes for tongue findings and visible tooth or tartar regions.
- Plan access
- Pro
- Capture requirement
- Phone camera with bright, even light
Best suited for
Organizing visible oral-hygiene observations and deciding what to photograph or ask about at a dental visit.
What you provide
One or more clear mouth photographs selected for general, tongue, or teeth-focused analysis. The region must be visible and in focus without filters.
What the result contains
- Mode-specific visual observations and an overall oral review
- Concern and urgency language with reasons and quality caveats
- Optional marked regions and follow-up questions grounded in the report
Important limitations
A phone photo cannot assess probing depth, cavities between teeth, bone, bite, or pathology below the surface. Pain, bleeding, swelling, ulcers that persist, trauma, or rapid change should be assessed by a dentist or doctor.
Technical processing details
- Each photo is checked and analyzed for the selected mode. Structured fields separate visible observations, concern level, area, urgency, reasoning, and image limitations.
- Focused spot processing can mark localized regions, while synthesis combines multiple images into an overall review. Follow-up chat is tied to the saved report context.
Storage and control
Reports, images, and chat can be saved to the signed-in account according to plan and retention settings.
Hair and follicle measurement
These tools work with magnified scalp images or explicit calibration. Their numbers are more sensitive to field of view, optics, segmentation quality, and sampling than broad phone-photo screening.
Tricho Checkup
BetaA guided close-up scalp session that connects calibrated capture, computer-vision hair detection, quantitative metrics, screening observations, and longitudinal history.
- Plan access
- Available across plans with plan-specific daily limits
- Capture requirement
- Dedicated scalp camera or known-magnification USB microscope
Best suited for
Repeated examination of the same scalp zone when the device magnification or field of view is known.
What you provide
A sharp close-up scalp image, zone label, camera or field-of-view calibration, and optional demographic context used only to frame the interpretation.
What the result contains
- Detected-hair count, density, average width, and diameter-variation metrics
- Terminal, intermediate, and vellus-style distributions with ratio context
- Screening observations, baseline comparison, and saved session history
Important limitations
A wrong field of view scales every physical measurement. Hair overlap, blur, oil, low contrast, and an unrepresentative scalp zone can change counts or width estimates. Values are screening measurements from imagery, not histology or a laboratory phototrichogram.
Technical processing details
- The guided session can hold several calibrated captures, while the immediate structured analysis is driven by the first image in the current workflow. Deterministic calibration utilities normalize returned width samples, reject implausible values, and derive comparable physical metrics.
- Counts, terminal and thinner-hair groups, ratios, density estimates, diameter variation, spot and scalp-condition observations are assembled into one session. Calibration confidence remains visible so a fallback estimate is not presented as a direct measurement.
Storage and control
Completed sessions can retain the source image, calibration, returned detections, metrics, and analysis in the user history. The current API does not return an annotated overlay image.
Hair Thickness
AvailableA manual measurement workspace for placing calipers across visible hair shafts and converting pixel widths to micrometers.
- Plan access
- Measurement is available; saved-session limits vary by plan
- Capture requirement
- Scalp camera required for meaningful physical units
Best suited for
Users who want to inspect the actual measurement anchors, correct them, and document repeated shaft-width samples instead of accepting an opaque average.
What you provide
One or more magnified scalp images plus magnification or a known horizontal field of view. EXIF details are read when present to help identify capture inconsistencies.
What the result contains
- Per-caliper width in micrometers, average width, and reference classification
- Editable hair-segment groups, overlays, crop, zoom, pan, and downloadable annotated images
- Saved reports with calibration, measurements, groups, notes, and optional AI discussion
Important limitations
The tool measures the visible image width at the chosen line. Focus, edge blur, strand angle, compression, and calibration dominate accuracy. Ethnic reference profiles provide context but do not diagnose miniaturization.
Technical processing details
- Pixel distance is converted through the active calibration. Plausibility checks warn when the physical width is unusually low or high and may suggest a calibration correction when the selected mode supports it.
- Measurements can be grouped into hair segments. Automatic grouping uses direction, proximity, and perpendicular alignment, while every anchor and group remains manually editable.
Storage and control
Measurements and reports are saved only when requested and within the plan’s session allowance. A fresh device-selected source image can be uploaded to the separate Gallery flow as soon as it is selected, even before the measurement report is saved.
Follicle Type Detection
BetaDetects visible follicular units and estimates how many hair shafts emerge from each observed unit.
- Plan access
- Pro
- Capture requirement
- High-resolution scalp-camera image
Best suited for
Reviewing the distribution of single-hair and multi-hair follicular units in a magnified sample.
What you provide
A close, sharply focused scalp image with individual openings and shafts separated well enough for the detector to resolve them.
What the result contains
- Detection boxes or markers with confidence
- Counts and distribution by visible follicular-unit type
- Annotated image and saved result when plan limits allow
Important limitations
Crossing hairs, cropped shafts, scale, oil, crust, shadow, and low focus can merge or split apparent units. The output describes visible image structures and does not establish follicle viability or donor suitability.
Technical processing details
- The detector proposes localized regions with confidence scores. Post-processing removes weak or overlapping candidates and groups results by the predicted number of visible hairs in the unit.
- The image overlay keeps each accepted detection spatially traceable, which makes false positives and missed units reviewable instead of hiding them behind a summary count.
Storage and control
Accepted analyses can be saved with the source image and structured detections under the user account.
Trichoscopy Analysis
In developmentAn experimental automated trichoscopy workflow with strand segmentation, width estimates, scalp observations, overlay review, and contextual chat.
- Plan access
- Pro while detection accuracy is being refined
- Capture requirement
- Scalp camera required
Best suited for
Previewing automated close-up analysis while retaining the original image and segmentation overlay for visual checking.
What you provide
A calibrated or known-magnification scalp image with visible hairs and scalp surface in focus.
What the result contains
- Segmentation overlay, detected-hair count, width and density estimates when calibration supports them
- Structured scalp and hair observations with uncertainty notes
- AI summary and follow-up chat linked to the analysis
Important limitations
This tool is explicitly in development. Automated polygons can miss fine, pale, overlapping, or blurred hairs. Treat all measurements as experimental screening values and verify important concerns professionally.
Technical processing details
- A remote segmentation model returns polygons for visible hairs. Robust geometry estimates cross-sectional widths while reducing the influence of spikes and malformed polygon vertices.
- When segmentation is unavailable, the system can preserve other screening observations but marks the measurement path as unavailable or low confidence. The report records that distinction rather than silently substituting a precise value.
Storage and control
Analyses and chat can be saved within Pro history allowances and deleted from the account.
Keratin Analysis
In developmentHighlights image regions that resemble keratin plugs, follicular casts, buildup, or related visible scalp-surface features.
- Plan access
- Experimental access is controlled by the active plan
- Capture requirement
- Scalp camera required
Best suited for
Experimental review of localized buildup in a magnified scalp image, with every accepted region shown on the image.
What you provide
A well-lit, close scalp-camera image. Clean optics and sharp focus help separate surface texture from blur and reflection.
What the result contains
- Annotated detections at the workflow’s fixed confidence settings
- Detection count, average confidence, and counts by predicted class
- Educational scalp-health context and optional follow-up
Important limitations
Sebum, scale, glare, debris, and keratin can look similar in a photograph. Detection labels are experimental and cannot identify an infection, inflammatory disorder, or histologic material.
Technical processing details
- The object detector runs with fixed confidence and overlap settings and produces candidate boxes, labels, and confidence values. The current interface does not expose those thresholds as user controls.
- Detection count, average confidence, and class counts are shown alongside an AI assessment. The deterministic detections and the interpretive text remain separate.
Storage and control
Intro, Basic, and Pro users currently pass the route gate, and saving is subject to the active plan’s analysis allowance. Free access is locked.
Consistent capture and change over time
Tracking tools preserve dates, zones, and comparable views. Their value comes from reducing capture variation before interpreting a difference as biological change.
Photo Diary
BetaA guided capture workflow for repeatable front, side, and top views with notes and dates.
- Plan access
- Available across plans with daily and history limits
- Capture requirement
- Any camera
Best suited for
Building a consistent visual record before using progression or four-view mapping tools.
What you provide
A set of guided photos captured or uploaded for the same session, plus optional notes. On-screen framing guides help align the subject and angle.
What the result contains
- Dated multi-angle diary entries with thumbnails and notes
- Reusable images for other TrichoLens tools
- Timeline playback or video where the active plan includes it
Important limitations
A diary does not normalize every difference. Hair length, styling, wetness, lighting, posture, and camera distance should be kept as stable as possible.
Technical processing details
- The diary stores capture metadata and session grouping rather than pretending that any two photographs are automatically comparable.
- Saved entries can feed later workflows, including Shape of Loss. Higher plans can create a timeline video from the sequence.
Storage and control
Diary images are stored in the user account under the active plan’s upload and retention rules.
Scalp Progression
AvailableOrganizes dated scalp photos into a timeline and analyzes visible severity, pattern, hairline, crown, urgency, and directional change.
- Plan access
- Basic and Pro
- Capture requirement
- Any camera, consistent capture strongly recommended
Best suited for
Reviewing a series over weeks or months rather than overreacting to one photograph.
What you provide
One or more dated images, optional notes, and ideally the same scalp zone, camera, lighting, and styling across sessions.
What the result contains
- Chronological cards, calendar view, and selectable image timeline
- Improving, stable, or worsening screening trend with the period and evidence count
- Exportable progression report, notes, overlays, and per-photo details
Important limitations
Trend logic cannot fully correct inconsistent capture. A change in flash, parting, hair length, or camera distance may exceed the real change being tracked. The trend is a screening signal, not a rate of biological hair loss.
Technical processing details
- Each photo keeps its own structured analysis. Timeline logic converts stage, severity, crown, hairline, and urgency signals into a cautious directional trend only when there is enough comparable history.
- Calendar and timeline views preserve chronology. Reports can show the earliest and latest evidence, changes in structured fields, and the most recent AI note.
Storage and control
Progression requires saved dated photos. Basic and Pro plans have different photo caps, and users can delete individual images or the full progression set.
Photo Gallery
AvailableA central library for images uploaded across TrichoLens tools, with organization and reuse controls.
- Plan access
- Available across plans with different storage limits
- Capture requirement
- Not applicable
Best suited for
Finding the source photo behind a saved result and reusing an existing capture without downloading and uploading it again.
What you provide
Images created by capture flows or uploaded to supported tools, along with dates, categories, and ownership metadata.
What the result contains
- Searchable and organized photo library
- Image preview, date and category management, deletion, and reuse in compatible tools
- Consultation status controls where the plan includes that service
Important limitations
The gallery stores and organizes evidence but does not make photos comparable by itself. Deleting an image can affect workflows that depend on that original file.
Technical processing details
- Gallery queries are scoped to the signed-in user. Saved image URLs are organized into visual tiles by source, date, and category; the current grid uses those saved URLs rather than separate reduced-resolution thumbnail assets.
- Ownership checks are repeated when another tool resolves a gallery image. A browser-visible URL alone is not treated as authorization to access another account’s file.
Storage and control
Gallery limits and retention vary by plan. Account export includes supported photo records and storage-file references, not a binary copy of every image.
Photo Calendar
AvailablePlaces saved scalp photos on a calendar so gaps, clusters, and capture consistency are visible at a glance.
- Plan access
- Pro
- Capture requirement
- Not applicable
Best suited for
Planning a repeatable capture schedule and locating images by when they were taken rather than by tool name.
What you provide
Saved account photos with capture or user-edited dates.
What the result contains
- Month-based photo timeline
- Day-level photo access and editable dates
- A visible record of capture frequency and missing intervals
Important limitations
Calendar spacing records when images were assigned, not whether the capture conditions were equivalent or whether a treatment caused a change.
Technical processing details
- Calendar grouping uses the stored photo date and user timezone presentation. Date editing changes organization metadata without altering the original pixels.
- Selecting a day exposes its associated photos in the calendar, where the user can open a lightbox, review source metadata, or edit the assigned date.
Storage and control
The calendar reads the user’s existing photo records. It does not create a second copy of every image.
Planning, product context, and simulation
These tools combine saved information or generate educational visualizations. They support organization and discussion, but they do not prescribe treatment or predict an individual medical outcome.
Comprehensive Hair Plan
AvailableSynthesizes saved scans, assessments, measurements, and user context into a structured planning workspace.
- Plan access
- Basic and Pro, with advanced protocol features on Pro
- Capture requirement
- Existing history is supported; new phone or gallery photos are optional
Best suited for
Turning scattered results into a list of priorities, questions, routines, and trackable protocol notes.
What you provide
Selected or recent TrichoLens records, profile context, goals, user notes, follow-up questions, and optional new scalp photos from the device or gallery.
What the result contains
- Cross-tool summary of observations and priorities
- Editable plan, protocol phases, notes, and chat grounded in saved context
- Red-flag reminders when prior records contain concern or urgency signals
Important limitations
The plan inherits uncertainty from every source record and may contain AI errors. Medication, procedure, supplement, and diagnosis decisions require a qualified clinician who can review history, examination, contraindications, and testing.
Technical processing details
- The planner builds a bounded context from the user’s own history, prioritizing recent and relevant records rather than exposing an unlimited raw account dump to the model. Newly added photos run through the Scalp Scan workflow and its combined review is added to planner context.
- AI synthesis proposes educational steps and questions. The protocol workspace remains user-editable so generated text is never treated as an immutable prescription.
Storage and control
Plans, protocols, notes, and saved chat belong to the signed-in user and can be exported or deleted through account controls.
Hair Porosity Test
BetaRecords a low, medium, or high porosity estimate from a strand float observation, with an optional photo interpretation path.
- Plan access
- Available across plans with plan-specific daily save limits
- Capture requirement
- Manual float observation or an optional phone photo
Best suited for
Building a repeatable record of how a clean strand behaves in water before using that band as context in the Product Match workflow.
What you provide
The observed position of a clean, dry, product-free strand in room-temperature water, or an optional photo of the test that the user reviews and confirms.
What the result contains
- Low, medium, or high porosity band with plain-language context
- Photo confidence and quality guidance when the image path is used
- Saved result history, notes, and a direct handoff to Product Match
Important limitations
The float test is influenced by residue, strand diameter, trapped air, water conditions, and user observation. It is an at-home estimate, not a direct measurement of cuticle structure.
Technical processing details
- The manual path maps floating, suspended, or quickly sinking behavior to a porosity band. The photo path requests an image interpretation with a confidence score, but the user’s confirmed band is what gets saved.
- The saved record can include method, selected band, float behavior, photo confidence, notes, and a photo only when the user chooses to retain it.
Storage and control
Porosity records can be saved within the daily plan allowance. The test photo is retained only when the user opts in; otherwise the saved record keeps the result without the image.
Product Match
BetaNormalizes a cosmetic product ingredient list and scores its likely fit against a selected or recently saved hair-porosity band.
- Plan access
- Available across plans; result depth and daily scan limits vary by plan
- Capture requirement
- No camera required; an ingredient-label photo is optional
Best suited for
Reviewing ingredient roles, benefits, cautions, and usage context before deciding what product questions to research further.
What you provide
A pasted ingredient list or a clear back-of-bottle label photo, product type, and the user’s selected porosity band. Extracted label text remains editable before scoring.
What the result contains
- Compatibility score, label, confidence, and best-fit porosity context
- Benefits, cautions, helpful ingredients, caution ingredients, and usage guidance when the plan includes them
- Normalized ingredient list, optional detailed ingredient notes, and a saved product shelf
Important limitations
An ingredient list does not reveal concentration, formulation behavior, contamination, allergy risk, or how a product performs on every person. OCR mistakes must be corrected before relying on the score.
Technical processing details
- Optical character recognition can extract label text from a photo. The product-match route then normalizes INCI names, tracks which ingredients were recognized, and applies structured scoring rules based on porosity, product type, and ingredient roles.
- Plan depth controls how much of the explanation is returned. Higher tiers can receive helpful and caution ingredient lists, usage guidance, or per-ingredient notes; the score remains educational rather than a safety clearance.
Storage and control
Products can be saved to the account within the active daily limit. A scanned label photo is saved only with user consent; otherwise the shelf keeps the entered text and result.
Transplant Simulator
BetaCreates an educational before-and-after visualization based on a selected target Norwood level while trying to preserve the original face and background.
- Plan access
- Pro
- Capture requirement
- Clear front-facing phone portrait
Best suited for
Exploring aesthetic goals and preparing reference questions for a qualified hair-restoration surgeon.
What you provide
A clear front portrait. The tool estimates the current Norwood level, lets the user confirm or select a better target, and asks for the desired simulated level.
What the result contains
- Estimated current Norwood level with confidence
- Selectable target stage and a generated visual simulation
- Original and simulated comparison plus saved history
Important limitations
The generated image is not a surgical plan or outcome prediction. It does not model donor supply, graft survival, hair caliber, curl, scarring, future loss, surgeon technique, or medical eligibility.
Technical processing details
- A structured vision pass estimates the visible pattern and confidence. The full image is then sent to image generation with text instructions to change only the hair and preserve the face, expression, ears, skin, neck, and background. There is no pixel mask that technically locks non-hair regions.
- The output and original remain available together so the visualization can be checked against the source. Saved records preserve current and target stages as context.
Storage and control
Original and generated images can be saved within Pro simulation and history limits and removed by the user.
History, consultation, support, and data controls
These services connect the analysis tools to saved context, human product guidance, technical support, and account-level privacy controls.
AI Chat History
ServiceCollects conversations explicitly saved from supported analysis tools and keeps them associated with their originating context.
- Plan access
- Paid plans; retention and count vary by plan
- Capture requirement
- Not applicable
Best suited for
Reviewing prior questions without relying on browser tabs or copying sensitive discussion into another app.
What you provide
Conversations saved with user consent from supported tool-specific chat interfaces.
What the result contains
- Browsable conversation list with dates and originating tool
- Full message review and deletion controls
- A path back to related tool context when available
Important limitations
Saved AI text can contain mistakes and should not be treated as medical advice. Chat history preserves what was said, not proof that the answer was correct.
Technical processing details
- History is queried by authenticated user ownership and tool context. Preview and detail views separate conversations from different tools and sessions.
- Retention windows and maximum saved counts are enforced from the active subscription tier.
Storage and control
Only conversations the product saves under the user account appear here. Users can delete history, and plan-based retention may remove older conversations.
Consultation
ServiceA scheduled one-to-one educational discussion for understanding the platform, organizing observations, and preparing better questions.
- Plan access
- Pro
- Capture requirement
- Uses existing records when the user chooses to discuss them
Best suited for
Users who want human help reading their own TrichoLens records or using the software more consistently.
What you provide
An available appointment slot, topic, optional notes, and any records the user decides are relevant.
What the result contains
- Confirmed appointment request and status
- A focused educational discussion about records, tracking, or product use
- Administrative notes associated with the request where applicable
Important limitations
This is not a medical consultation. It cannot diagnose, prescribe, clear a procedure, or replace a licensed clinician. Urgent symptoms require appropriate local medical care.
Technical processing details
- Booking claims an available slot transactionally so the same time is not assigned twice. The user can view waiting or in-progress status while service staff manage consultation-status updates.
- The service is educational and product-oriented. It is intentionally separated from medical diagnosis, prescribing, or emergency care.
Storage and control
Booking details, topic, status, and service notes are stored with account context. Current account-deletion logic removes direct identity fields from completed consultation logs but can retain free-text service and audit records.
Product Support
ServiceA structured way to report technical, billing, account, data, or feature-request issues to the TrichoLens team.
- Plan access
- Signed-in users
- Capture requirement
- Not applicable
Best suited for
Problems with the app or account that are not medical questions.
What you provide
A support category, subject, and detailed message submitted by the authenticated user.
What the result contains
- Submission confirmation or an actionable validation error
- A categorized support record for follow-up
Important limitations
Support cannot interpret symptoms, diagnose a condition, or provide emergency assistance.
Technical processing details
- The API verifies the user token, validates the request fields, and records a support request with the account context needed to respond.
- Medical concerns are kept out of the support workflow and directed to an appropriate healthcare professional.
Storage and control
The submitted request is stored with the authenticated account and handled under the privacy policy.
Account and Data Controls
ServiceCentral controls for subscription state, supported data export, category-level deletion, and account closure.
- Plan access
- Signed-in users
- Capture requirement
- Not applicable
Best suited for
Reviewing the controls currently available for saved photos, sessions, posts, chat, subscriptions, and the account itself.
What you provide
An authenticated account and explicit confirmation for sensitive actions.
What the result contains
- Downloadable export of the collections supported by the current export route
- Bulk deletion for the displayed data categories and a permanent account-deletion control
- Subscription management and current-plan status
Important limitations
Permanent deletion is intentionally destructive and may not be reversible. Current export and deletion coverage does not include every auxiliary product collection or every retained consultation, community, security, billing, and audit record. Contact support when a record is not covered by the displayed controls.
Technical processing details
- Export requests gather supported user-owned records into a portable response, with a current cap of 500 documents per included collection. Deletion endpoints verify identity and process the categories shown in account settings.
- Subscription actions such as pause, downgrade, cancel, or portal access use dedicated server routes and show the resulting effective access state.
Storage and control
This service manages the account’s stored data rather than creating a new analysis record.
