HAIR TYPE: All Hair Types, Damaged Hair / COLLECTION: Première / Kérastase Première Concentré Liquide Resurfaçant is an intense repairing treatment for all types of damaged hair. Your hair is stronger, healthier, and shinier – as if renewed. 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 absorbs 3 times the amount of calcium. This calcium overdose attacks the hair fiber inside and out – both cortex and cuticle are damaged leading to dull, stiff hair that’s prone to breakage. Kérastase Première Concentré Liquide Resurfaçant works to neutralize calcium overdose and reduce breakage, ensuring your hair is no longer stiff and dull, but supple and shiny. Further calcium damage is prevented and the surface of the hair is sealed and smoothed, leaving it soft, and easy to style.
