Description
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.

Science
How To Dramatically Reverse Persistent Damage?
Kerastase discovered the reason behind damage that keeps coming back: CALCIUM!
3X more calcium is absorbed with damaged hair as it is more porous (vs healthy hair), leading to a calcium overdose
PERSISTENT damage happens when calcium sneaks in-between keratin chains at every contact with water, breaking their links, making hair rigid, stiff and easy to break
BUILD-UP of calcium on the outside makes hair rough and dull
Pure Acids Concentration
Free hair from calcium overdose with citric acid, an organic acid that acts from core to surface, to neutralise dullness and stiffness. Once calcium is removed Glycine, an amino acid, penetrates hair’s inner layer to deeply repair. As a results broken links between keratin chains are reconnected, dramatically reducing breakage.
