Kerastase Fusio-Dose is the first entirely customizable treatment of highly concentrated skincare active ingredients, capable of solving various hair problems. The beauty of the Fusio-Dose is that you can combine different hair treatments in ONE by mixing the initial dose of goodness concentrate with different types of boosters to address multiple hair concerns. The new Kerastase Fusio Dose allows the creation of up to 30 unique combinations and treats a number of hair issues related to dryness, breakage, color, hormonal changes, and curly and blond hair. In essence, this freshly fused treatment instantly and visibly transforms your hair and provides lasting results.


Kerastase Fusio Dose is most effective when applied to hair section by section. If your hair is short or not very thick, you can visually determine which sections of hair have received treatment and which have not as you go. However, if you have long or thick hair, consider using hair clips to differentiate one section from the next while applying treatment.
Concentrate and boosters must be mixed together and applied directly to the hair using either a spray bottle or your hands. Massage the treatment into your hair thoroughly, making sure to condition the entirety of each length. Keep track of which sections of hair you applied treatment to as you go. Give sections of your hair that are particularly dry or damaged a bit of extra attention.
When you cover all of your hair, allow the treatment to sit for one minute, then rinse it with water. You should see a noticeable difference in your hair immediately after applying the Kerastase Fusio Dose. Repeat this process once a week to keep your hair as healthy and shiny as possible. Depending on hair type and environmental conditions, one treatment should last from 5-10 shampoos.

  1. Shake well
  2. Remove the cap from the concentrate vial
  3. Snap-on the applicator pump (purchased separately) or use finger tips to evenly apply the treatment to towel-dried hair
  4. Comb through with a wide-tooth comb to ensure even coverage
  5. Leave it on for at least 60 seconds (This treatment works instantly)
  6. Rinse out

    Fusio dose

    This is perfect. You get different variations to see what works best on your hair. Much better than the at home version. I am a fan.

    Fusio Dose

    Posted by Patricia on 2nd Nov 2020

    This was an easy to apply, super effective deep conditioning treatment. I had been experiencing dry brittle hair with lots of shedding and breakage. After using the Fusio Dose my hair feels so much healthier and the shedding is gone. I will purchase again.

    Very good! If you have time leave it on your hair for at least 2 minutes, the results are much better this way. Otherwise just apply as recommended and your hair will be light and shine. They say it supposed to less for up to 10 shampoos, in my opinion for a week (not much longer)
