  • For Weakened Hair, Prone to Breakage From Brushing

  • Boosts scalp cells and hair
  • Boosts hair fiber retention
  • 1 Booster fills 10 Vials of Concentre
  • Cruelty-free/No Animal Testing


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 apply 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, and then rinse it out with warm water. You should see a noticeable difference in your hair immediately after applying the Kerastase Fusio Dose. To keep your hair as healthy and shiny as possible, repeat this process once a week. One treatment depending on hair type and environmental conditions should less from 5-10 shampoos.

  1. Remove the cap from the concentrate vial
  2. Pour the consistency of the booster into the concentre vial
  3. Put on the sprayer (snaps on)
  4. Shake well
  5. Spray evenly on towel dried hair
  6. Comb through with a wide-tooth comb
  7. Leave it on for 10 seconds (This treatment works instantly)
  8. Rinse out

Note: Please clean the dispenser by spraying a warm water through it. It is reusable sprayer and can be use many times. For additional help please refer to video

    Kerastase Fusio Genesis - LOVE LOVE LOVE

    Posted by Kirsten Ranger on 23rd May 2022

    I have been struggling with female pattern hair loss and general breakage. I already use the Kerastase Genesis shampoo and conditioner and love it, but I don't always have time to go to the salon for a fusio treatment. After shopping around online, I discovered Valley Beauty and was blown away by their selection. This product plus the concentre arrived quickly and is super easy to use with everything you need in one small package! I only need to use it once a month but my hair is loving the extra care. I have already ordered more from the Genesis line including refillable shampoo that I didn't even know existed. Valley Beauty is cheaper than any other place I have found, plus the selection and shipping is fabulous!

    I like to give my hair a weekly treatment to calm down frizziness and combat the dull look my hair gets, especially in winter. This treatment lets me target areas that are in poor shape, like the ends, as well as put in all over. When combined with concentre oleo-fusion I can really see a difference after -- my hair is shiny and easy to manage. You don't need much, and it rinses out really well. My hair loves this stuff!
