Kérastase Shampoo for Damaged Hair Bain Décalcifiant Réparateur 250 ml

Decalcifying and repairing shampoo for treated and damaged hair

The Kérastase Première Bain Décalcifiant Réparateur is a professional sulfate-free shampoo formulated for damaged, bleached or chemically treated hair.
Designed to counteract the effects of hard water, it removes excess calcium that weakens the hair fiber and promotes breakage.

An innovative treatment from the Kérastase Première line, selected and tested in Celebre Store salons, hairdressers for 4 generations since 1914.

What is Bain Décalcifiant Réparateur

It is a repairing and decalcifying shampoo that works with a dual action:

1. Removes excess calcium deposited by hard water, which causes dull, stiff and brittle hair

2. Repairs internal keratin bonds, strengthening the hair structure from within

The white, creamy texture transforms into a rich, enveloping lather, leaving hair soft, shiny and visibly healthier.
