Safe & secure checkout guarantee.
'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.
Bottle made of 95% recycled plastic*
Recreates 99% of hair's original strength**

| How to use | 'Apply generously on wet lengths before shampoo and massage throughout. Leave on for 5 minutes. Don’t rinse. Layer Première Bain directly on top to maximize efficacy. Rinse and follow with Première Fondant or Mask. |

| Ingredients | 3% Citric Acid to decalcify. This organic acid captures and dissolves the calcium deposits that make hair stiff and prone to breakage. It works from the core to the surface to make hair healthy and alive from root to tip. 5% Glycine to repair. Once the calcium is removed, glycine penetrates the inner layers of the hair helping to reconnect each broken keratin link and reinforce the entire hair structure. Reducing breakage, restoring hair strength and resilience.
