Description:
Deeply fortify and renew your hair with Kérastase Résistance Masque Extentioniste, an intensive strengthening hair mask formulated to repair and reinforce fragile lengths. Powered by the Creatine R Complex, Ceramides, and Taurine, this rich treatment penetrates the fibre to rebuild internal strength, prevent breakage, and smooth damaged cuticles. Designed to promote healthy hair growth from root to tip, it restores softness, shine, and elasticity for visibly stronger, longer, and more resilient hair.

Who It’s For:
Ideal for anyone with weakened, breakage-prone, or slow-growing hair caused by heat, colouring, or environmental stress. Suitable for all hair types, including fine to thick textures.

What It Does:

• Strengthens the hair fibre to reduce breakage and split ends

• Supports healthy growth and long-lasting resilience

When To Use:
