Product Description
Protect your hair from heat damage with the Kérastase Extentioniste Thermique. This gel-cream formula strengthens your locks to prevent split ends and damaged tresses.
The Extentioniste Thermique is a lightweight, gentle formulation which restores hair without causing any tension or breakages. This leave-in treatment is the perfect way to protect your precious lock by sealing hair lengths. Once the cream is applied it gets to work by encouraging elasticity, while also adding a boost of hydration. Not to mention, it protects hair up to heat of 230°C, so is perfect to use with heat styling tools.
The formula is enriched with a nourishing combination of glaçage thermo-ceal, creatine R™ and taurine. These active ingredients are full of amino acids and lipids which are responsible for strengthening your hair fiber and creating a healthy scalp environment.
This product goes well with Kérastase Resistance Ciment Anti-Usure Conditioner.
