Kérastase Fusio-Dose is an innovative professional hair treatment that delivers highly concentrated active ingredients tailored specifically to your hair’s condition. Following a detailed hair diagnosis, your stylist creates a customized formula by combining a concentrated booster with a targeted concentrate to address concerns such as dryness, damage, frizz, color fading, lack of volume, or weakened hair.

Unlike traditional conditioning treatments, Fusio-Dose provides immediate, personalized care that penetrates the hair fiber to restore strength, softness, hydration, and shine from the very first application.

Suitable for all hair types, Kérastase Fusio-Dose is the ideal treatment for anyone seeking fast, visible results while maintaining healthy, beautiful hair between salon visits.
