The starting point
Three reference photos following a precise protocol, and your starting numbers: days between washes, minutes spent styling, how the ends feel. Your memory will forget, the journal will not.
Le Journal des 30 Jours
You have 30 days to judge your products, refunded otherwise. This journal is the protocol that makes your verdict undeniable: reference photos, real measurements, a guided ritual. Print it or keep it on your phone.
No sign-up. We do not even ask for your email.
The ritual, guided
The right technique for each product, a typical week, and wash-by-wash tracking. Half of all hair care disappointments come from a good product used badly.
The verdict
You retake the photos, revisit your numbers, and compare. Convinced: you carry on. Not convinced: you get your money back, even on opened bottles. That is the deal.
Why this journal exists. In this market everyone promises and nobody verifies. We have only four products and a 30-day guarantee that covers even opened bottles. This journal makes it undeniable: your decision will rest on your photos and your numbers, not on an impression. The full terms are on the page Returns and refunds.
