Kérastase Première Concentré Liquide Resurfaçant 400 ml

Professional restructuring and decalcifying treatment for severely damaged hair – Salon size

The Kérastase Première Concentré Liquide Resurfaçant 400 ml is a specialised salon technical treatment designed for hair severely damaged by chemical treatments, bleaching and hard water.

A professional treatment by Kérastase, ideal to integrate into the Première layering technique to achieve intense, targeted repair of the hair fibre.

What the Concentré Liquide Resurfaçant is

It is an intensive restructuring and decalcifying treatment that:

• Neutralises excess calcium absorbed by porous hair

• Reduces breakage

• Seals and smooths the hair surface

• Restores elasticity and shine

Treated hair is more porous and absorbs more calcium from water. This excess attacks both the cortex and the cuticle, leaving hair dull, stiff and fragile.

The Concentré Liquide Resurfaçant removes up to 38% of excess calcium* and helps prevent further damage.

*Instrumental test after 6 applications
