Kerastase's first pre-shampoo treatment that removes calcium and repairs all types of damaged hair. Calcium-rich water can further damage hair that is already delicate because it is excessively treated or bleached. Being more porous, damaged hair absorbs more calcium than natural hair. The concentration of pure acids in this treatment therefore has a dual action: it decalcifies the hair from this excess calcium and repairs it from the inside, restoring the strength of the hair and improving its stiff and dull appearance. With its clear gel consistency, this brilliant product dramatically repairs persistent damage, repairing broken bonds between keratin chains to strengthen hair structure. The hair is therefore stronger, healthier looking and shinier, as if renewed. Leave Kérastase Concentré Décalcifiant Ultra-Réparateur on and then directly apply Kérastase Première Bain Décalcifiant Réparateur as an additional layer to optimize effectiveness. Rinse, and follow with Première Fondant or Mask.
