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 APPLY - 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.*
