KERASTASE PREMIERE DECALCIFYING REPARATIVE SHAMPOO 8.5 fl. oz.

Kérastase Première Décalcifying Reparative Shampoo is a professional repairing shampoo designed to address hair damage caused by calcium buildup (often from hard water) while also strengthening chemically treated or over-processed hair.

It works on two main fronts:

First, it helps remove excess calcium deposits from the hair fiber. Hard water minerals can accumulate over time, leaving hair feeling rough, dull, and more prone to breakage. This shampoo gently decalcifies the hair to restore softness and improve how other treatments absorb.

Second, it focuses on reparative care for damaged hair bonds. It supports the hair fiber’s internal structure to reduce breakage and improve overall strength and resilience, especially for hair weakened by bleaching, coloring, or heat styling.

The texture is typically a rich, creamy shampoo that lathers well and leaves hair feeling cleaner, smoother, and less stiff after rinsing. It’s often used as the first step in the Kérastase Première system, followed by complementary treatments like conditioners or masks for deeper repair.
