myhairline.ai is a free browser-based tool that analyzes your hair loss using artificial intelligence. Upload a photo from any device, and within seconds you receive a Norwood stage classification, hairline recession measurement, and personalized treatment information based on your results.
What the Tool Does
The analysis provides three core outputs from a single photograph:
- Norwood stage classification: Your hair loss is categorized on the 7-point Norwood Scale, from Stage 1 (no significant loss) to Stage 7 (most extensive pattern)
- Hairline position measurement: Precise distance between your eyebrows and current hairline, measured against the ideal forehead height of approximately 6.5 cm for males and 5.5 cm for females
- Graft estimate: Based on your Norwood stage, the tool provides the typical graft range needed for restoration
| Norwood Stage | Typical Grafts Needed | Estimated Hairs (at 2.2 per graft) |
|---|---|---|
| Stage 2 | 800-1,500 | 1,760-3,300 |
| Stage 3 | 1,500-2,200 | 3,300-4,840 |
| Stage 3V | 2,000-2,800 | 4,400-6,160 |
| Stage 4 | 2,500-3,500 | 5,500-7,700 |
| Stage 5 | 3,000-4,500 | 6,600-9,900 |
| Stage 6 | 4,000-6,000 | 8,800-13,200 |
| Stage 7 | 5,500-7,500 | 12,100-16,500 |
How the Technology Works
Facial Landmark Detection
The tool uses MediaPipe's 468-point facial landmark model to map your face from a single photograph. These landmarks create a precise mesh of reference points covering your forehead, temples, eyes, nose, and jawline.
From this mesh, the system identifies:
- The position of your current hairline relative to your brow ridge
- The degree of temporal recession on both sides
- The symmetry of hair loss patterns
Norwood Classification Algorithm
Once facial landmarks are mapped, the algorithm measures hairline recession against established Norwood Scale criteria. Each stage has specific characteristics:
- Stages 1-2: Minimal to slight temple recession. The hairline remains close to the juvenile position or has matured slightly.
- Stage 3: Deep temple recession forming a visible M-shape. This is the threshold where most surgeons consider transplant candidacy.
- Stages 4-5: Progressive loss with separation between the frontal hairline and vertex area.
- Stages 6-7: Extensive loss with only a horseshoe band of hair remaining.
The algorithm removes the subjective variation that occurs when different clinicians assess the same patient. A 2024 study found that dermatologists disagreed on Norwood staging in up to 28% of borderline cases. AI provides a consistent baseline.
Privacy-First Architecture
All processing happens locally in your browser. Your photograph is analyzed on your device using client-side machine learning inference. No images are uploaded to or stored on external servers. When you close the browser tab, the data is gone.
How to Get the Best Results
Photo quality directly affects analysis accuracy. Follow these guidelines:
- Lighting: Use even, front-facing light. Avoid overhead lighting that casts shadows on the forehead.
- Angle: Face the camera straight on with your forehead fully visible. Pull back any hair that covers the hairline.
- Distance: Position yourself at arm's length from the camera.
- Background: A plain, contrasting background helps the algorithm distinguish the hairline boundary.
What to Do With Your Results
Your Norwood stage determines the next steps:
Stages 1-2: Monitor and Prevent
At these early stages, medical therapy alone may be sufficient. Finasteride halts further loss in 80-90% of users, with 65% experiencing regrowth. Minoxidil provides 40-60% moderate regrowth. Use the tool every 3 to 6 months to track whether your stage is stable or progressing.
Stage 3: Evaluate Options
This is the decision point between medical therapy and surgical restoration. A transplant at Stage 3 requires 1,500 to 2,200 grafts. Costs range from $1,500-4,400 in Turkey to $6,000-13,200 in the USA.
Stages 4-7: Plan for Surgery
Higher Norwood stages typically benefit from hair transplant procedures. FUE can extract up to 5,000 grafts per session with 90-95% survival rates. FUT allows up to 4,000 grafts. DHI handles up to 3,500 grafts with the advantage of using a Choi Implanter Pen for simultaneous channel creation and placement.
The safe extraction limit of 45% of donor follicles sets the ceiling for total available grafts across all procedures.

Limitations
The tool provides classification and measurement, not medical diagnosis. It does not:
- Distinguish between androgenetic alopecia and other conditions (alopecia areata, telogen effluvium, traction alopecia)
- Perform scalp biopsy or trichoscopy
- Prescribe medication
- Replace a board-certified dermatologist for complex cases
Use your results as informed data to bring into clinical consultations, not as a standalone diagnosis.
