Masque Filler Réparateur

An anti-breakage repairing resurfacing hair mask that restores moisture and strengthens all types of damaged hair.

15ml / 75ml / 200ml


Product Description

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.

Key Ingredients

A chain of amino acids that refills hair surface with matter.

Once calcium is removed, this amino acid penetrates hair's inner layer to deeply repair.

How To Dramatically Reverse Persistent Damage?

Kerastase discovered the reason behind damage that keeps coming back: CALCIUM!

3X more calcium is absorbed with damaged hair as it is more porous (vs healthy hair), leading to a calcium overdose 

PERSISTENT damage happens when calcium sneaks in-between keratin chains at every contact with water, breaking their links, making hair rigid, stiff and easy to break

BUILD-UP of calcium on the outside makes hair rough and dull

Pure Acids Concentration

Free hair from calcium overdose with citric acid, an organic acid that acts from core to surface, to neutralise dullness and stiffness. Once calcium is removed Glycine, an amino acid, penetrates hair's inner layer to deeply repair. As a results broken links between keratin chains are reconnected, dramatically reducing breakage.
