Strand
Hair changes too slowly to judge in the mirror. Strand photographs it the same way every week and keeps an honest, private record you can look back on.

Know your hair, without the guesswork.
The same four photos, every week
Guided capture takes your hairline, crown, temples and part line in the same order, with last week's photo shown faintly over the camera so the framing matches.
An honest record
Every check-in lands in a private photo timeline. Put this week beside any earlier one. If you choose AI analysis, you also get a Hair Score that only calls a trend when it is bigger than photo-to-photo variation.
Private by design
No account. Photos stay on your phone and out of cloud backups. They leave it only if you turn on AI analysis and tap Analyse. Export everything or delete everything at any time.
A tracking tool, not a medical device.
The Hair Score is an estimate from photos, and the app explains how it is made and how much it moves on its own. Strand does not diagnose or recommend treatments. If you are worried about your hair, a GP or dermatologist can help.
