What clients and stylists said after their first ONYX service
ONYX is not a traditional keratin treatment. Instead of coating the hair with an alcohol-based formula, it opens the cuticle in a controlled low-pH environment so the actives penetrate and restructure the fiber from the inside out. It is fully rinsed out before ironing, so there is no smoke and no burning. Trusted by professionals in 20+ countries since 2006.


Every stylist who completes the class receives the COCOCHOCO ONYX Certificate of Completion, signed by the company's leadership and your training program manager. It recognizes you as qualified to perform professional ONYX Mineral Complex treatments, and it is yours to frame at the station.
Shown as a sample. Certificates are issued individually after the class and cannot be purchased.
