Intensive Reinforcing Care for Damaged, Over-Processed Hair

Size: 10x12ml /

Kerastase Fusio-Dose Concentre Resistance is a part of the Fusio Dose family of professional hair treatments designed to resolve concerns in damaged and weakened hair. It is enriched with highly concentrated active ingredient Ceramides to repair the damage done by heat styling tools or environmental aggressors by infusing hair fiber with a nourishing dose of goodness and sealing the outer layer of the hair cuticle to prevent future breakage. It instantly strengthens the hair and transforms it into more nourished, softer locks with high shine and less surface damage. Kerastase Fusio-Dose Concentre Resistance is meant to treat damaged hair as the main concern and must be combined with the Kerastase Fusio Dose booster of your choice that activates the treatment and at the same time addresses a secondary hair concern. The beauty of the Fusio-Dose is that you can create a tailor-made solution based on your hair needs and combine different hair treatments into ONE by mixing the concentrate with different types of boosters to address your hair needs. The freshly fused treatment with an initial dose of goodness will fundamentally treat your hair and immediately transform it for lasting results.

  • 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 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. 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 60 seconds (This treatment works instantly)
  8. Rinse out

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