Kérastase Première’s anti-breakage filler is a rich mask for all types of damaged hair that repairs and rebuilds the inner strength of over-processed hair and protects against further breakage. Hair is stronger, and more beautiful.

While calcium is naturally present in hair, when hair is damaged it absorbs too much, leading to a calcium overdose. At this high level, calcium weakens the inside and the outside of the hair fiber. With its luxurious creamy texture, this decalcifying mask soaks into hair, delivering extra conditioning care to maximize hair recovery, particularly after chemical processing. A genuine hair savior, its dual action rebuilds the hair structure, smooths the surface, and radically reduces breakage, so hair goes back to its healthiest, strongest, most beautiful state.

Use the power of layering for maximum results. Start with a powerful dose of repairing actives in Kérastase Concentré Décalcifiant Ultra-Réparateur, then layer on Kérastase Bain Décalcifiant Réparateur without rinsing first for strong, shiny, smooth hair. Use the mask twice a week to boost the effect. Your Kérastase Première products all work together for extra restructuring and decalcifying care.
