Decalcifies damaged hair – Helps target excess calcium that can accumulate on porous, compromised hair and contribute to stiffness and breakage.

Repairs and strengthens – Helps reinforce weakened hair fibres for stronger, more resilient hair.

Deeply conditions damaged lengths – Provides intensive care to restore softness, flexibility and manageability.

Restores smoothness and shine – Helps transform rough, dull and brittle hair into smoother, softer and healthier-looking hair.

What Is It?

KERASTASE Première Decalcifying Repair Duo is a professional shampoo and mask routine designed to address damaged hair affected by excess calcium buildup.

Damaged hair becomes more porous and can accumulate calcium from water. This excess calcium can contribute to stiffness and make already weakened hair more vulnerable to further breakage.

KERASTASE Première Bain Décalcifiant Réparateur Shampoo is a professional sulfate-free decalcifying shampoo that helps remove excess calcium while cleansing damaged hair and supporting the repair process.

KERASTASE Première Masque Filler Réparateur provides intensive conditioning care to damaged lengths. Its rich formula helps strengthen compromised fibres, smooth the hair surface and restore softness and movement without leaving hair feeling unnecessarily heavy.

Together, they create an effective two-step routine for hair that feels stronger, smoother, softer and healthier-looking.
