Kérastase Première Decalcifying Repairing Shampoo Conditioner Duo

RESTORES HAIR'S ORIGINAL STRENGTH

Pre-Shampoo: Our first pre-shampoo hair treatment, suitable for all hair types, removes excess calcium and helps repair all types of damaged hair. This includes damage by heat tools, colour treatment, bleaching, over-processing and other types of hair damage.

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 and has a dual action: 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 which is formulated with the amino acid Glycine, penetrates the hair's inner layer, to help deeply repair the hair.

With its transparent gel texture, this pre-treatment helps repair persistent damage, working to reconnect broken keratin links and reinforce hair strength and structure. Hair is left stronger, healthier-looking, and shinier - as if renewed. Leave on KÉrastase Première Decalcifying Repairing Pre-Shampoo Treatment without rinsing, and then layer with KÉrastase Première Decalcifying Repairing Shampoo, then rinse out both.

Finish with KÉrastase Première Decalcifying Repairing Conditioner as a final step.

Shampoo: Recreates 99% of hair's original strength while providing up to 73% more shine by freeing hair from calcium build-up that leads to breakage.

A white creamy shampoo that transforms into a luxurious foam, its dual action fights the calcium overdose from hard water that attacks your already damaged or bleached hair, leaving it dull, lifeless, and limp.

It also helps restore keratin links within the hair shaft, repairing hair at the core. Your hair feels smooth, manageable, and bouncy.

We recommend layering KÉrastase Première Decalcifying Repairing Shampoo on top of KÉrastase Decalcifying Repairing Pre-Shampoo Treatment without rinsing first for maximum results.

Finish your routine with other products from the Première range, like the Repairing Conditioner or the Anti-Breakage Repairing Filler Mask.

Our first Decalcifying Repairing Conditioner suitable for all hair types, removes excess calcium and helps repair all types of damaged hair. This includes damage by heat tools, colour treatment, bleaching, over-processing and other types of hair damage.

When hair is already damaged, excess calcium will accumulate, further weakening the cuticle and cortex of the hair. KÉrastase Anti-Rigidity Decalcifying Repairing Conditioner dual-action fights the effect of the calcium overdose, first decalcifying, then repairing hair.

The rigid feel of hair, due to calcium in hard water, is neutralised, to protect against breakage, and helps repair hair from the inside out.

KÉrastase Première Anti-Rigidity Decalcifying Repairing Conditioner envelops hair with its lightweight jelly-like texture and helps restore hair strength and resilience. Your hair is left amazingly soft, supple, and up to 7x smoother.

First, use KÉrastase Première Decalcifying Repairing Pre-Shampoo treatment, and without rinsing, layer on KÉrastase Repairing Shampoo for maximum decalcifying and repairing results.

Then follow with the Decalcifying Repairing Conditioner.

Finish with the KÉrastase Première Repairing Anti-Frizz Filler Serum for even more restructuring hair care.
