Première Decalcifying Repairing Shampoo - For all types of damaged hair

Première Decalcifying Repairing Shampoo

Many women report persistent hair damage despite using repair products. Kérastase has traced this issue back to calcium found in hard water. This mineral accumulates within porous hair, breaking keratin bonds and causing brittleness.

The Première Decalcifying Repairing Shampoo leverages 8% pure acids to remove harmful calcium and repair the hair structure at its core. This process restores original strength and shine, providing a professional solution for chemically treated hair.

Ingredients and their benefits

• Citric acid: This organic acid acts both on the surface and deep within to eliminate calcium buildup, effectively neutralizing dullness and stiffness.
• Glycine: Once the fiber is decalcified, this amino acid penetrates the hair core to repair its structure. Keratin chain links are restored, drastically reducing breakage.
