Before beginning your treatment, your stylist will diagnosis your hair. Depending on what your hair needs most, they will select a [Concentré] and [Booster] to combine and spray it onto the hair, at the backwash. Within 5-minutes your tailor-made treatment will be complete, and you’ll be flaunting lush, re-energized hair all day, everyday!

It replaces your fondant or mask in-salon treatment, but it isn’t the same. Fusio-Dose molecules are up to 100 times smaller than a traditional haircare product and it is supplemented with skincare actives.

No, it is a Kérastase exclusive salon service. The Fusio-Dose custom-blended formula requires a professional evaluation of your hair to determine the best mix for you.

Every salon visit! You stylist will diagnose your hair and create a freshly-mixed formula that specifically targets your current hair concerns with the correct blend of concentrated actives. Your stylist will then recommend and adapt the formula each time to suit your hair needs as they evolve with every visit.

Fusio-Dose transforms your hair in less than 5 minutes, with a custom-blended mix that addresses 2 hair needs in 1 application!
