Norwood Scale
Find your Norwood-style stage from photos.
The Norwood scale describes how a hairline and crown change in appearance. From four guided photos, AI suggests where your visible pattern sits today — an appearance-based reference for tracking, not a medical diagnosis.

How it works
Four photos. One baseline. Every change tracked.
Same four angles, every time — so each new scan compares fairly to your very first.
Front · crown · temple · back
Capture
Four guided angles in about 30 seconds — the same views every time.
Hairline · density · scalp
Read
AI reads each angle for hairline shape, crown density, and scalp surface.
Usable · limited · low-light
Qualify
Every reading shows its confidence — limited views are flagged, not guessed.
Your baseline, revisited
Compare
Save it, rescan later, and see exactly what moved.
What each scan reads
Signals you can actually compare.
Every reading is appearance-based and carries its own confidence — built for tracking, not for a verdict.
Hairline & recession
Visible hairline shape and recession signals across the front and temples.
Crown density
How dense the crown looks from the top and back angles.
Scalp surface
Appearance-based scalp surface signals where they are visible.
Hair attributes
Texture, wave, and coverage read from the guided photos.
Confidence on each reading
A clear confidence level so partial views never fake certainty.
A baseline to track
Saved once, revisited later — the point is the change over time.
Questions
Good to know.
What is the Norwood scale?
It is a common way to describe how a hairline and crown change in appearance, from an even hairline through more advanced patterns. We use it as a visual reference for tracking, not a medical grade.
How does the photo-based Norwood test work?
From four guided photos, AI reads your visible hairline and crown pattern and suggests where it sits on an appearance-based scale — with the confidence of each reading shown.
Is the Norwood stage a diagnosis?
No. It is an appearance-based reference for tracking change over time, not a medical diagnosis. A qualified professional is the right call for medical questions.
Do I need an account?
No. Preview your result first; sign in only to save a baseline and track your stage over time.
Will my photos be kept private?
Yes. They are processed for your report only — never used for AI training or advertising.
A note on transparency
Informational and cosmetic — not a diagnosis.
ScalpAnalysis AI reads appearance-based signals and tracks visible change over time. It does not diagnose, treat, cure, or prevent any condition.
If you have pain, sudden shedding, or signs of infection, a qualified professional is the right next step.
