Photographic hair tracking

See how your hair is really changing.

Take the same four guided photos every few weeks. StrandMetrics compares them over time with AI analysis, and a human reviewer can assess them when you want a closer look.

Consistent by design

The same four views, every time.

Guided framing and on-screen checks keep each Hair Check comparable with the last, so you see real change rather than a different angle or different lighting.

How it works

Three steps to a clear record.

  1. 01

    Take your Hair Check

    Follow on-screen guides to photograph your crown, hairline and temples in a few minutes. Use your phone on its own, or pair it with your computer using Remote View.

  2. 02

    See your AI analysis

    StrandMetrics AI describes what is visible in each photo and compares new Hair Checks with your earlier ones, so changes are easier to follow.

  3. 03

    Add a human photographic review

    Choose Expert for a written photographic assessment from a human reviewer, with a follow-up every three months.

Pricing

Simple, transparent plans.

Both plans include guided Hair Checks and your full photographic record. Expert adds a human reviewer.

Human review

Your hair. Reviewed by a real person.

£14.99

per month · includes StrandMetrics AI

No free trial

Human photographic review when paid Expert starts, then every three months. Yearly Expert is not available.

  • Everything in StrandMetrics AI
  • Written human review of your photographs
  • First assessment at paid start, then every three months
  • No free trial — billed from the start

Your photographs are reviewed by a hair assessment reviewer with a science background and experience in the hair transplant industry. This is a non-clinical photographic review, not a medical diagnosis.

4 photographic reviews a year: 1 when you start, then 1 every 3 months.

What Expert is and isn't

Your review describes what's visible in your photographs: hairline, temples, mid-scalp and crown, and changes since earlier Hair Checks. It doesn't diagnose causes or medical conditions, and it doesn't recommend or prescribe treatments.

Reviews are counted in 12-month periods from your Expert start date. Each review becomes available on its 3-month date and must be used within the 12-month period it belongs to. Unused reviews expire at the end of that period, and any you haven't used end if your Expert subscription ends.

£14.99 a month, including StrandMetrics AI. Renews monthly until you cancel in Settings or the billing portal.

Questions

Frequently asked questions.

Anything else? Read our privacy notice and terms.

How does the free trial work?

StrandMetrics AI includes a 3-day free trial for new subscribers. A payment card is required, and you are not charged during the trial. After 3 days your plan renews at £3.99/month (or £29.99/year) unless you cancel before the trial ends. Expert has no free trial.

Can I cancel?

Yes. Cancel any time in Settings or the billing portal. Your saved Hair Checks and reports stay available to view, export or delete.

What is the difference between AI and Expert?

StrandMetrics AI (£3.99/month) analyses each Hair Check automatically and compares it with your earlier checks. Expert (£14.99/month) includes everything in AI plus a written photographic assessment from a human reviewer, with a follow-up every three months.

Is StrandMetrics a medical diagnosis?

No. StrandMetrics provides photographic hair observations and tracking, not medical diagnosis or treatment. It does not diagnose conditions or recommend treatments. If you are concerned about hair loss, speak to a GP, pharmacist or dermatologist.

Who can see my photos?

Your photos are stored privately in your account. If you use StrandMetrics AI, and only with your consent, your photos are sent to OpenAI, our AI provider in the United States, to produce an automated description. If you choose Expert, and only with your consent, your reviewer sees the photographs and answers needed for your review. You can export or delete your data, or withdraw consent, in Settings.

Who reviews Expert photographs?

Your photographs are reviewed by a hair assessment reviewer with a science background and experience in the hair transplant industry. This is a non-clinical photographic review, not a medical diagnosis.

What do I need to take a Hair Check?

A phone with a camera. On-screen guides help you frame each view. For crown photos you can pair your phone with a computer using Remote View, so you can see the camera on a larger screen.

Start with a 3‑day free trial.

Then £3.99/month or £29.99/year, depending on your plan. A payment card is required, and your subscription renews automatically unless you cancel during the trial.
