Our first pre-shampoo treatment that removes excess calcium and helps repair 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 can absorb up to 3 times more calcium than natural hair. This treatment formulated with a concentration of pure citric acid and glycine has a dual action: it decalcifies hair from this calcium overdose, and works to repair it from the inside out, restoring hair strength, and reversing its stiff, dull appearance.

With its transparent gel texture, this pre-treatment helps repair persistent damage, working to reconnect broken keratin links and reinforce hair strength and structure. Hair is left stronger, healthier-looking, and shinier – as if renewed. Leave on Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment without rinsing, and layer with Kérastase Première Decalcifying Repairing Shampoo. Team with Kérastase Première Anti-Rigidity Decalcifying Repairing Conditioner as a final step.
