Shop Première Decalcifying Repairing Pre-Shampoo Treatment - 250ml

The first Kérastase 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.

Key Ingredients
- 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

Benefits:
- Comes in a transparent gel texture
- Repairs persistent damage, reconnecting broken keratin links to reinforce hair strength and structure
- Leaves hair stronger, healthier-looking, and shinier – as if renewed
- Free from colourants

How to Use:
- Apply generously on wet lengths before shampoo and massage throughout
- Leave on for 5 minutes
- Don’t rinse
