Kérastase Concentré Décalcifiant Ultra-réparateur Première

Concentré Décalcifiant Ultra-réparateur Première Kérastase
Pre-shampoo repair treatment, damaged hair

Première Ultra-Repairing Decalcifying Concentrate deeply repairs all types of damaged hair.
The calcium in hard water can further damage already damaged/sensitized hair. Because it is more porous, damaged hair absorbs 3 times more calcium than natural hair, and enters a cycle of persistent damage.
The unprecedented 8% concentration of pure repairing acids (glycine and citric acid) in this professional treatment has a dual action: it eliminates the overdose of calcium in hair responsible for breakage, and repairs it from the inside out by repairing the keratine* chains. Hair is stronger, healthier, shinier and on the move. Repairs 96% of hair damage in 1 usee** and 92% of women say their hair is durably repaired.***
Leave Ultra-Repairing Decalcifying Concentrate on for 5 minutes, then superimpose Repairing Decalcifying Bath without rinsing, for an amplified decalcifying and repairing action. Follow with Masque Filler Réparateur or Fondant Fluidité Réparateur for added softness and surface repair. Finish with Fondamental Filler Serum and/or Repairing Gloss Oil, for heat protection and intense shine.
