The ultra-personalized in-salon hair treatment that adapts to your needs for the ultimate hair transformation

Introducing renovated Fusio Dose from Kérastase


It has been 50 years since Kérastase first conceptualized the art of the in-salon care ritual, inspired by the professional know-how of expert hairstylists. Each ritual, adapted to every kind of hair, promised efficient results that led to improved textures, and extraordinary sensoriality, in order to transform hair care into a sublime experience. Kérastase is now synonymous with the art of personalized hair care, with visibly effective solutions to emphasize the unique needs of each woman in an innovative and precise manner. A tailor made hair ritual is the new luxury!


In 2011, Kérastase launched the first personalized mix that would treat the hair surface without weighing down the fiber. Four concentrated care formulas were mixed with four powerful active ingredients to create many possibilities for custom-designed treatments that would transform the hair instantly, and with lasting results. 2016 sees the emergence of a new system, with Kérastase’s Fusio Dose pushing the very limits of what is possible in terms of customization, with more efficient, more personalized, more ergonomic formulas that take the blending process through better stages.


The new Fusio Dose range consists of four concentrates and five boosters in perfectly adjusted dosages, with high performing active ingredients selected in their most pure and concentrated state for their fast action on the hair fiber. First, we have the concentrates that take care of your primary hair concerns. Concentré Oléo-Fusion blends natural jojoba and avocado oils for instant nutrition and softness; Concentré Pixelist contains micro-luminescent active ingredients to add radiance; Concentré Vita-Ciment contains ceramide to repair and transform, while Concentré Densifique is enriched with Pro-Calcium to instantly make the hair stronger and more supple. The Fusio Dose is then mixed with a booster that treats your secondary hair concern. Booster Brilliance with zinc gluconate and Vitamin E derivatives adds incredible radiance; Booster Densité with Cation Polymer adds immense body to hair; Booster Reconstruction with anti-damage complex and ceramide plumps and strengthens hair; Booster Nutrition with Royal Iris nourishes hair to leave it soft and dazzling while Booster Discipline contains Morpho-Keratine to make the hair fiber manageable, leaving hair silky and full of movement.


After analyzing the hair through a professional hair diagnostic, the stylist can combine the four concentrates and five boosters in an array of options to create a Fusio-Dose ritual designed for a woman’s specific needs. These deliver the best possible blend of pure active ingredients in the highest concentration to instantly and spectacularly transform the hair. The accompanying personalized, in-salon ritual is both luxurious and sensorial. For each care application, Fusio Dose allows 20 tailor-made combinations that can be easily added to any Kérastase salon service such as hair coloring, cutting or styling. The concentrates and boosters come together to form the core of a whole new system that beats at the heart of the best salons, while transforming hair into the best, most beautiful it can be.
