2. What is the difference between the Booster vs. Concentre?
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.
3. How many mixes are possible with Fusio-Dose?
With 6 Concentrés and 5 Boosters available, there are up to 30 different mixes possibilities. It allows you to target two unique hair concerns at the same time.
4. Who is this custom hair treatment right for?
Even those who take excellent care of their hair sometimes need a boost. Stress, styling, and environmental factors can weaken the hair gradually, causing it to look dry and dull, behaving in strange, unruly ways. When hair begins to exhibit signs of stress, there is a quick, easy fix available at your nearest Kérastase salon—our signature Fusio-Dose custom hair treatment. With a fresh, personalized mix of a Concentré and a Booster, Fusio-Dose immediately transforms your hair based on your stylist’s expertise for 95% less breakage*, 70% more shine** and 24h anti-frizz protection***

5. How does it work & how long does the custom hair treatment take?
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!
6. Is Fusio-Dose the same as a hair mask?
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.
7. Can I do a Fusio-Dose at home?
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.
8. How do I know which Fusio-Dose mix is right for me?
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.
9. How often can I book a Fusio-Dose custom hair treatment?
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. Find your nearest Kerastase salon and book a Fusio Dose service today!
