CONCENTRÉ DÉCALCIFIANT ULTRA-RÉPARATEUR, 250 ML

PREMIÈRE CONCENTRÉ DÉCALCIFIANT ULTRA-RÉPARATEUR by KÉRASTASE is a decalcifying pre-shampoo treatment to repair all types of damaged hair. With every contact with water, calcium accumulates and penetrates between the keratin structures and destroys their bonds, making the hair harder and brittle from the inside. Externally, calcium accumulates on the surface of the hair, which leads to loss of shine and lack of smoothness. In addition, damaged hair can absorb up to 3 times more calcium from running water (than undamaged hair) due to porosity, causing calcium overload. PREMIÈRE double-action range, enriched with an effective 8% complex of citric acid + glycine*, as well as peptides. For decalcification, citric acid works on the surface and also penetrates inside the hair, helping to eliminate the overaccumulation of calcium - to counteract the loss of shine and smoothness of the hair. When calcium build-up is eliminated, glycine penetrates the hair to repair damaged keratin bonds to reduce breakage. As a strengthening ingredient, peptides help to fill and close the hair cuticle - to strengthen the surface, moisturize and shine. In this way, the PREMIÈRE range has a double effect: reducing the overaccumulation of calcium, which provoked brittleness, as well as restoring the damaged keratin bonds of the hair. Restoration of up to 99% of the original hair strength!** PREMIÈRE CONCENTRÉ DÉCALCIFIANT ULTRA-RÉPARATEUR pre-shampoo care with a clear gel structure helps remove calcium build-up, which reduces hair damage.
