Corterion — hair, measured

Certainty. Engineered.

Haircare is bought blind. We make it measured.

Why we exist

You spend on your hair with no measurement, no trend line, no answer to "is this working?" Confidence deserves better instruments.

The loop

Measure. Understand. Act.
Then measure again.

01

Measure

A calibrated scan of your scalp, in seconds — the same image, the same way, every time. That is what makes change visible.

02

Understand

One score you can follow, built from real measurements — density, coverage, scalp condition — not a quiz.

03

Act

A routine matched to your scalp, your water, your city. When the measurements say you need a specialist, we say so.

04

Prove it

Rescan in 30 days. Keep what works. Change what doesn't. Your hair finally has a record.

01 — The instrument

Calibra

Clinical trichoscopy for dermatologists and hair clinics. Standardised optics, a per-region capture protocol, quality-gated images — and a report your patient can hold.

In practice

In consultation rooms today.

Calibra puts objective measurement into the clinic — the same protocol that will power everything we build next. Numbers for the clinician. A clear answer for the person in the chair.

02 — Next

Your hair, measured.
Your ritual, yours.

A smaller instrument is coming — one that lives on your shelf, knows your scalp, your water, your city, and builds your routine around what your measurements actually say. Not another product. The end of guessing.

The platform
Device

Measurement, calibrated and comparable — the part everyone else skips.

Intelligence

A score and a routine that learn from what actually happened to your hair.

Care

Products and people — routines when routines are enough, specialists when they aren't.

Outcomes

Every rescan makes the next recommendation better. For you, and for everyone after you.

Hair first. Scalp next. Skin after that.
Instruments for confidence, built to compound for twenty years.

Mission

Care is bought blind. People spend on their hair and skin with no measurement, no trend line, no proof that anything works.

We build the instruments that end the guessing — clinical-grade measurement in dermatologists' hands today, a personal instrument on your shelf next. Every scan makes the next answer better, and the record compounds: measurement into understanding, understanding into outcomes people can see.

We're making care measurable.
