Kérastase Première Decalcifying Reparative Shampoo 250ml (8.45floz)

Kérastase Première Decalcifying Reparative Shampoo 250ml repairs damaged hair by gently eliminating excess calcium build-up, restoring vitality, and reducing breakage.

Kérastase Première Decalcifying Reparative Shampoo 250ml is a sulfate-free decalcifying shampoo for hair that is damaged or weakened by chemical treatments. It cleans the scalp and hair gently, and it helps remove excess calcium that builds up due to hard water. Because damaged hair absorbs more calcium, it becomes rigid and prone to breakage. However, with this formula, you are able to address that overload from the first wash. The shampoo transforms from a creamy texture into a smooth, rich lather. As it works, it targets calcium inside and on the surface of the hair. In fact, its dual action supports both detoxification and repair. As a result, hair becomes easier to detangle, and it feels more flexible. In addition, restoring keratin links helps improve the structure of the hair fiber over time.

The formula is powered by two key ingredients. Citric Acid acts from the core to the surface of the hair, and it helps dissolve excess calcium that causes dullness and stiffness. Meanwhile, once the calcium is lifted, Glycine penetrates the inner layer of the fiber to reinforce it. This combination supports internal repair, therefore reducing breakage linked to repeated exposure to hard water. Because calcium accumulation often affects tone and shine, consistent use helps maintain a smoother and more uniform appearance. The shampoo also prepares the hair for the remaining steps of the range, so it can be used before treatments or masks. Overall, the formula supports healthier-looking hair by addressing one of the main causes of persistent damage: calcium overload. With regular use, hair becomes softer, more manageable, and less prone to breakage.
