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)

    An absolute MUST buy and use to correct dry, damaged hair! 10 mins of magic! Will purchase again! NOTE: It must be used with a base and I chose the Kerastase Fusio Dose Concentre Oleo-Fusion bc this is a good base for dry hair, accordioning to my hairdresser.
