Kerastase Premiere Anti-Breakage Repairing Filler Mask - 6.76 oz - Decalcify, Repair, Premiere Your Strongest Hair

Persistent damage is a real drag, and it often has an unexpected culprit: water. If your hair feels brittle, stiff, and prone to breakage, it's likely dealing with a calcium overdose from hard water sneaking in between the keratin chains, which makes hair weak, rigid, and easy to snap. Meet your new hair hero: the Kérastase Première Masque Filler Réparateur Anti-Breakage Repairing Hair Mask. This rich, luxurious, creamy mask is designed for all types of damaged hair, especially over-processed strands, working a dual-action magic to rebuild internal structure, smooth the hair surface, and radically reduce breakage. It’s a true hair savior, soaking deeply into the hair fiber to deliver intense conditioning care and maximize recovery, particularly after any chemical processing. Get ready to dramatically reverse that damage, restoring your hair to its healthiest, strongest, and most beautiful state.

This concentrated formula features a powerful blend of key ingredients to combat damage at its source. Once the hair is free from the dulling, stiffening effects of calcium buildup, the formula’s Peptides—a chain of amino acids—go to work by refilling the hair surface with matter. At the same time, Glycine, another amino acid, penetrates deep into the inner layer of the hair fiber to repair internal damage, reconnecting broken keratin links to reinforce the structure. The result is hair that feels replenished from the inside out and visibly more resilient, helping you achieve up to 98% less breakage and 97% inner structure reinforcement. Plus, this intensive treatment leaves your hair with a luminous shine and an alluring, subtle woody fragrance with bright notes of mandarin.

Using this anti-breakage filler mask is an absolute treat for damaged tresses, giving you a smooth, high-shine finish. For the ultimate hair recovery ritual, apply this mask to wet hair after shampooing with the coordinating Première Bain Décalcifiant Réparateur. You can use it twice weekly for intensive nourishment, alternating with a lighter conditioner as needed. The ultimate pro-tip for maximum efficacy is layering the Kérastase Première Concentré Décalcifiant Ultra-Réparateur Pre-Shampoo Treatment first, followed immediately by the Bain Décalcifiant Réparateur Shampoo, and then treating with this Masque Filler Réparateur. You'll love how the rich, white, creamy texture melts into your hair, leaving it softer, stronger, and more manageable with up to 86% more moisture.
