Kerastase Premiere Decalcifying Repairing Shampoo (250ml) & Conditioner (200ml) for Damaged Hair with Pure Citric Acid & Glycine Twin offers two of Kerastase's best-selling products, specially formulated to help remove calcium build-up from all hair types, preventing further damage and restoring dry, brittle hair.
Calcium in water can further damage already delicate over-processed or bleached hair. Being more porous, damaged hair can absorb up to 3 times more calcium than natural hair. This hair treatment is formulated with a concentration of pure citric acid and glycine. It has a dual action. Firstly, it decalcifies hair from this calcium overdose and works to repair it from the inside out, restoring hair strength, and reversing its stiff, dull appearance. Once excess calcium is removed, this product penetrates the hair's inner layer, to help deeply repair the hair.
