This professional Kérastase shampoo gently cleanses both hair and scalp while eliminating damaging calcium deposits. It restores hair health from within, making it less brittle, shinier, and visibly healthier.

Its creamy formula transforms into a luxurious foam, specifically targeting excess calcium found in hard water that makes already fragile hair even duller. By repairing keratin bonds within the hair shaft, this miraculous treatment leaves hair smooth, shiny, and much easier to style.

For an optimal care experience, apply Kérastase's ultra-repairing Première Concentré decalcifying treatment before using the Première Bain decalcifying repairing shampoo (do not rinse the Concentré before applying the Bain). Together, these products deliver intense repair, revealing hair that is remarkably shiny, strong, and easy to style.
