With up to 30 unique combinations, NEW Fusio Dose in-salon treatments instantly transform your hair. Composed of two parts, a concentre and a booster, Fusio Dose treatments are performed by trained Kerastase stylists to help you address your main hair concerns and are formulated based on your hair goals.

Starting with the Concentre, these highly concentrated vials address your main hair concern. A concentre is then mixed with a Booster, packed with powerful skincare active ingredients, to help you reach your hair goals.

It all begins with an idea. Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference.

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

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.

Your hairdresser will perform a detailed professional diagnosis of your hair to define your main hair need and Concentré. Your hairdresser will then discuss your hair goals to pick the right booster.

Every salon visit! Your 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!
