Kérastase Première Decalcifying System Reparative Shampoo is a repairing cleanser designed to remove calcium build-up caused by hard water while restoring strength, smoothness and shine to damaged hair.

This advanced formula gently cleanses the scalp and fibre while helping reverse stiffness and breakage linked to mineral accumulation. It works deep within the hair structure to reinforce weakened strands, improve flexibility and support healthier-looking lengths.
