Masque Filler Réparateur anti-breakage and protective hair mask from the Première series, specially developed by Kérastase for damaged hair care - is suitable for all damaged hair types. It repairs over-processed hair from the inside out and protects against breakage. It makes hair stronger and smoother with regular use. Although calcium is naturally present in the structure of the hair, damaged hair absorbs this mineral 3 times more than it should whenever it comes into contact with water. This situation causes excess calcium accumulation in the hair. High levels of calcium – weakens the hair strands both internally and on the surface. Masque Filler Réparateur, a repairing mask for damaged hair that gently envelops the hair with its creamy texture, quickly penetrates into the hair and provides extra care to maximize the healing process of the hair, especially after chemical treatments. Thanks to its double-effect repair, it rebuilds the internal structure of the hair - smoothes its surface and radically reduces breakage, allowing the hair to return to its healthiest, strongest and brightest state. Apply Kérastase Première Concentré Décalcifiant Réparateur as the first treatment and at the end of the waiting period, use Kérastase Bain Décalcifiant Réparateur Shampoo without rinsing.
