Kérastase Première Huile Gloss Réparatrice is a restorative hair care oil that gives intense shine to the hair. It has a formula suitable for all hair types. Calcium - like many minerals, is found both in the body and in water and is important for hair health. However, the porous structure that occurs in chemically treated and damaged hair can lead to calcium accumulation in the hair strands with each washing process. As a result, the hair can become dull and brittle. Huile Gloss Réparatrice special care oil for damaged hair has a double effect structure. Offers repair and maintenance. It seals the split hair ends thanks to the high concentration of active ingredients it contains. (It creates a protective barrier on the hair surface.) In this way, it increases the resistance of the hair and reverses the dull appearance of damaged hair. Thus, the hair becomes stronger and 4 times brighter.* Use Kérastase Première Concentré Décalcifiant Réparateur as a pre-treatment to reduce calcium accumulation in damaged hair. At the end of the waiting period, apply Kérastase Bain Décalcifiant Réparateur Shampoo without rinsing the Concentré. Then use Kérastase Fondant or Masque Fluidité Réparateur. Finally, complete the care and repair process by using Kérastase Huile Gloss Réparatrice protective and smoothing oil for damaged hair.
