What your mirror can't measure.
A clamp closes on a lock of hair. 20 seconds later, 5 optical measurements become a score out of 100.

What the clamp reads
Five optical measurements. No guesswork.
The jaws hold about a hundred strands flat, under known lighting. What is read is the light that surface sends back. Nothing else. Open a row to see why it earns its weight.

The gesture
Twenty seconds, three times a week.
01
Clip
On a lock, at mid length, always in the same place. The jaws spread the strands flat, and that is what makes two scans comparable.
02
Scan
20 seconds. The clamp lights the lock from three known angles and reads what comes back. No photograph is taken, no face is seen.
03
Read
The 5 measurements land in the app, become a score, join your trend, and come back out as three concrete actions.
The app
A measurement is useless without what comes next.
A line, not a lone number
One score on its own says nothing. What matters is the slope. The app keeps every scan and shows you the thirty-day trend against your own reference bands.

The five measurements, broken out
When the score moves, you see exactly which pillar moved it. Frizz is normalised so everything reads the same way round: higher is better.

Optimal
Frizz is shown normalised: 76 out of 100 corresponds to 24 strays per centimetre.
Three things to change
Recommendations come from your own series, not from a generic guide. Every action names the pillar it targets and the effect expected, including when that effect is none.

Method
How light becomes a number.
Every measurement is mapped onto a scale where a hundred is always better, Frizz included, then weighted. The weights are public and fit on one line.
Shine
A closed cuticle reflects like a smooth surface. An open one scatters. Shine is the first thing the eye reads.
Frizz
Frizz is the one pillar where less is better. It rises with humidity and with breakage, which makes it an early signal.
Thickness
Diameter moves slowly. It is the baseline of your hair, the one that says whether the long-term trend is rising or falling.
Color
Colour drifts before the eye notices. Sun, chlorine, a fading dye job: it all shows up here.
Surface
This is the finest of the five. It moves within days and responds quickly to a change of routine.
You are the reference
Your first scan records your starting line. Everything after compares to it. An 82 on coily hair and an 82 on straight hair mean the same thing: above your own baseline.
Calibration matters more than the sensor
A reference disc is scanned once a month. Without it the optics drift and the trend lies. It is the boring part of the product, and it is also what makes it credible.
What this is not
No diagnosis, no promise of regrowth, no medical advice. The clamp measures a surface. It knows nothing about your follicle, and we will not pretend otherwise.
What the optics see
About a hundred strands held flat, lit from three angles. Shine, deviation from the axis, diameter, colour and scale state are all read off this same image.

Questions
What we get asked most.
How can a clamp measure hair?
It doesn't measure a hair, it measures a lock. The jaws hold about a hundred strands flat, under known lighting. What is read is the light coming back off that surface, not the biology of the follicle.
Does it work on curly, coily or colour-treated hair?
Yes. Your first scan records your reference and everything after that compares you to you, not to a norm. A score of 82 on coily hair and a score of 82 on straight hair mean the same thing: you are above your own line.
Do I have to scan every day?
No. A scan takes 20 seconds and three scans a week are enough to hold a trend. People testing a treatment scan more often, and that is their call.
This isn't a medical device, is it?
No, and we don't present it as one. No diagnosis, no promise of regrowth. An optical measurement, a trend, and routine recommendations.
What happens after the twelve months included?
The app moves to €9 a month. The clamp keeps working and your data stays exportable, subscription or not.
When do I get the clamp?
