Kérastase - Diagnose Your Hair

You dare, we care

Everyone's hair is different. At Kérastase we want to care for all hair types, every hair desire, every hair concern.

Professional expertise

Since 1964, Kérastase’s philosophy has been to bring to its customers the best professional care for hair. The perfect hair care regime for the ideal result, requires personalisation and professional expertise. We work with the best hairdressers to provide the ultimate solutions to care for hair.

The Kérastase Experience

Each Kérastase experience begins with a professional, in-depth scalp and hair diagnosis performed by a Kérastase Expert. You are then offered a personalised hair profile complete with recommendations for in-salon Rituals and at-home care.

Perfect routine

Your Kérastase Diagnosis will offer you the most accurate product & Ritual recommendation to suit your unique desires and needs.


Far more than the place to get your root touch-up or an occasional trim, book an appointment at your nearest Kérastase salon for a complimentary personalized hair diagnosis or ask your hairdresser about the signature and salon-exclusive Fusio-Dose treatment. You can also stop by anytime to browse and shop the complete Kérastase range, no appointment necessary.
