Product Description:

• This Premiere Concentré Décalcifiant Ultra-reparateur by Kerastase is 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.
  

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.
  

Caution & Warnings:

• In case of contact with eyes, rinse them immediately and thoroughly. If irritation occurs reduce the frequency of use.
  

Ingredients:

• 8% pure acids concentrations to decalcify and deeply repair.
  Citric acid: an organic acid that acts from core to surface to deeply eliminate calcium overdose, neutralising dullness and stiffness.


• Glycine: once calcium is removed, this amino acid penetrates hair's inner layer to deeply repair.


• As a result, broken links between keratin chains are reconnected, dramatically reducing breakage.
