KERASTASE Première Bain Décalcifiant Réparateur Repair Shampoo 250ml is a professional sulfate-free decalcifying and repairing shampoo for damaged, bleached and over-processed hair. Formulated with Citric Acid and Glycine, it gently cleanses while helping remove excess calcium buildup from hard water, reduce breakage and restore strength, smoothness, shine and healthy-looking movement.

What Is It?

KERASTASE Première Bain Décalcifiant Réparateur Repair Shampoo 250ml is a sulfate-free professional shampoo developed specifically for damaged and over-processed hair.

The Première range addresses a less obvious contributor to persistent hair damage: excess calcium accumulation.

According to KERASTASE, damaged hair is more porous and can accumulate calcium from water. This excess calcium can contribute to stiffness, dullness and breakage in already weakened hair. Bain Décalcifiant Réparateur combines cleansing with a decalcifying and repairing action to help address this buildup while caring for damaged strands.

The creamy shampoo transforms into a rich foam while remaining sulfate-free.

When used as part of the complete Première routine, KERASTASE reports:

93% stronger hair
2x smoother hair
73% shinier hair

The result:

Cleanse → Decalcify → Repair → Strengthen → Smooth → Shine
