Premiere Decalcifying Repairing Pre-Shampoo Treatment - 8.45 oz

Give your hair a powerful head start on repair with the Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment, a breakthrough first step in reversing damage before you even shampoo. Specifically formulated for over-processed, weakened, or brittle hair, this pre-shampoo treatment targets one of the hidden causes of hair breakage: calcium buildup from hard water. By removing these excess minerals, it allows for deeper penetration of reparative ingredients and sets the stage for more effective hair restoration.

Infused with citric acid and glycine, this innovative formula gently decalcifies the hair fiber, softens rigid strands, and primes your hair for repair—without stripping moisture or affecting color-treated hair. It works at the core of the hair fiber to reinforce strength, improve elasticity, and reduce breakage caused by internal imbalances and external aggressors. Hair feels noticeably smoother, softer, and stronger after just one use.

Part of the cutting-edge Kérastase Première collection, this pre-shampoo treatment is an essential addition to any damaged hair routine. Use it before your regular shampoo to transform hair from the inside out, enhance the effectiveness of subsequent products, and unlock a visibly healthier, more resilient hair texture. The 8.45 oz bottle offers professional-grade care with every application.
