The first pre-shampoo treatment that removes calcium and fully repairs all types of damaged hair.
Hard water containing calcium can further damage weakened, bleached or over-processed hair. Damaged hair, because it is more porous, absorbs three times more calcium than natural hair. The concentration of pure acids in this treatment acts in two ways: it removes excess calcium and it repairs the hair from the inside, restoring strength and restoring suppleness and shine.
With its transparent gel texture, this miraculous hair treatment dramatically repairs persistent damage by repairing keratin bonds to strengthen hair and its structure. Hair is stronger, shinier and healthier-looking – as if completely revived. Apply Kérastase Ultra-Repairing Decalcifying Concentrate to hair; do not rinse. Then apply Kérastase Première Bain decalcifying repair shampoo to optimize the decalcifying and repairing effects. For even more remarkable results, follow with Fondant Fluidity Repair Conditioner.
