Product Description
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**
*Excluding colorants and additives
**Instrumental test after 6 applications of Première Concentré + Bain + Fondant/Masque

How to dramatically reverse persistent damage?
Kérastase discovered the reason behind damage that keeps coming back: CALCIUM!
Damaged hair is porous and absorbs 3 times more calcium from water (vs healthy hair) leading to a calcium overdose.
At each contact with water, calcium accumulates creating persistent damage. Calcium sneaks in-between keratin chains, and breaks their links, making hair rigid, stiff and easy to break.
On the outside, calcium builds-up, on the scales, making hair rough and dull.
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.
