Kérastase Première Masque Filler Réparateur Hair Mask 200ml is an intensive repairing treatment designed to restore strength, resilience, and hydration to damaged and over-processed hair. This rich, deeply nourishing mask targets calcium buildup from hard water, which can weaken the hair fiber and cause breakage. Formulated with Citric Acid and Glycine, it works to dissolve calcium deposits, deeply fortify hair structure, and replenish lost moisture. The result is stronger, silkier, and more manageable hair with improved elasticity and shine. Ideal for chemically treated, bleached, or brittle hair, this mask provides long-lasting repair and protection against future damage.
