Reverse hard water damage with Kérastase Première Decalcifying Shampoo. This reparative formula transforms into a rich foam to gently cleanse the scalp and hair while removing calcium buildup that can weaken chemically treated or sensitized hair. Infused with citric acid and glycine, it helps restore keratin links, smooth the fiber, and bring bounce and shine back to damaged strands.
Ideal for all hair types exposed to hard water or in need of deep repair.
