Kérastase Pre-Shampoo Treatment Première Concentré Décalcifiant Ultra-Réparateur 250 ml

Descaling and repairing treatment for damaged hair – 250 ml

The Kérastase Première Concentré Décalcifiant Ultra-Réparateur 250 ml is the first pre-shampoo treatment designed to remove calcium from hard water and deeply repair all types of damaged, treated or bleached hair.

Sensitized hair is more porous and absorbs a greater amount of calcium than natural hair. This buildup makes hair stiff, dull and more prone to breakage.

A professional treatment from Kérastase, selected in Celebre Store salons — hairdressers for 4 generations since 1914.

What is the Concentré Décalcifiant Ultra-Réparateur

It is a high-concentration pre-wash treatment of pure acids with a dual action:

1. Removes calcium buildup from the hair fiber, eliminating excess calcium

2. Repairs internal keratin bonds, strengthening the hair structure

Its transparent gel texture penetrates deeply and helps counter persistent damage. Hair appears stronger, healthier, more elastic and shinier.
