Kérastase Première Pre-Shampoo Treatment for Damaged Hair – 250 ml

Kérastase Concentré Décalcifiant Ultra-Réparateur – Pre-Shampoo Treatment for Damaged Hair

A dual-action pre-shampoo treatment from Kérastase that removes calcium buildup and repairs damaged hair, enhancing its strength, smoothness, and shine.

This is the first pre-shampoo treatment that deeply removes calcium buildup while fully repairing all types of damaged hair. Hard water containing calcium worsens damage in sensitized, over-processed, or lightened hair. Because damaged hair is more porous, it absorbs three times more calcium than healthy hair.

Formulated with a high concentration of pure acids, this innovative gel-textured treatment has a dual-action effect: it removes excess calcium and restores internal hair strength by rebuilding broken keratin bonds, reducing dullness, roughness, and breakage. Hair is visibly renewed, shinier, and stronger, as if regenerated from within.

For best results, do not rinse after applying. Instead, layer with Première Bain Décalcifiant Réparateur shampoo directly over the treatment to intensify the decalcifying and repairing effect. Finish your routine with Fondant Fluidité Réparateur or the mask from the Première range.
