DECALCIFYING RESURFACING CONCENTRATE
Product Description
If you have damaged or bleached hair, discover the dramatic repair of this intense resurfacing and decalcifying treatment. Treated hair is more porous than natural hair, so it can absorb up to 3 times the amount of calcium. This calcium overdose attacks the hair fibre inside and out – both cortex and cuticle are damaged leading to dull, stiff hair that’s prone to breakage. Kérastase Première Decalcifying Resurfacing Concentrate works to neutralise the overdose of calcium and reduce breakage***, ensuring your hair is no longer stiff and dull, but supple and shiny. Hair is protected from further calcium damage and the surface of the hair is sealed and smoothed, leaving it soft, and easy to style.
If you have damaged hair, you will find Kérastase Première Decalcifying Resurfacing Concentrate an excellent addition to the professional layering technique. In the salon, start with Kérastase Première Decalcifying Repairing Pre-Shampoo Treatment, and without rinsing, layer on Kérastase Première Decalcifying Repairing Shampoo for additional decalcifying and repairing results. Then, experience the super repairing power of Kérastase Première Decalcifying Resurfacing Concentrate, layered with the Kérastase Première Anti-Breakage Repairing Filler Mask.

How To Dramatically Reverse Persistent Damage?
Want to know the reason behind damage that keeps coming back? CALCIUM!
3x
Damaged hair is porous and absorbs up to 3x more calcium from water (vs healthy hair) leading to a calcium overdose.
PERSISTENT
At each contact with water, calcium accumulates creating persistent damage. Calcium sneaks in-between keratin chains, and breaks their links, making hair rigid, stiff and easy to break.
BUILD-UP
On the outside, calcium builds-up on the scales, making hair rough and dull.
8% pure acids concentration
Free hair from calcium overdose with citric acid, an organic acid that acts from core to surface, to neutralise dullness and stiffness. Once excess calcium is removed, Glycine, an amino acid, penetrates hair's inner layer to help deeply repair. As a results this helps reconnect broken links between keratin chains, helping to reduce breakage.
