Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment is an intensive first-step repair treatment designed to remove calcium build-up from hard water while strengthening damaged hair before cleansing.

This powerful pre-shampoo treatment works deep within the hair fibre to neutralise excess calcium that causes rigidity, dullness and breakage. It restores flexibility, improves strength and prepares hair to receive the full benefits of the Première repair routine.

Used before shampooing, it helps reinforce weakened hair structure while improving softness, shine and manageability from the very first use.

Ideal for damaged, colour-treated or chemically processed hair exposed to hard water or styling stress.
