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.​

**Instrumental test on sensitised hair after continued use of the full Première routine vs. non- sensitised hair.
