Kérastase Premiere Concentré Décalcifiant Ultra-Réparateur 250ML

The first pre-shampoo treatment that removes calcium and fully repairs all types of damaged hair.
Hard water with calcium can further damage already delicate over-processed or bleached hair. Because it’s more porous, damaged hair absorbs 3 times more calcium than natural hair. This treatment’s concentration of pure acids has a dual action: it decalcifies hair from this calcium overdose, and repairs it from the inside out, restoring hair strength, and reversing its stiff, dull appearance.

With its transparent gel texture, this brilliant hair savior dramatically repairs persistent damage, reconnecting broken keratin links to reinforce hair strength and structure. Hair is left stronger, healthier-looking, and shinier – as if renewed. Leave on Kérastase Concentré Décalcifiant Ultra-Réparateur without rinsing, and layer with Kérastase Première Bain Décalcifiant Réparateur for extra decalcifying and repairing action. Team with Fondant Fluidité Réparateur as a final step.
