The Extentionist Mask from the Résistance from Kérastase extentionist Mask is designed for women who want long, beautiful hair. It boosts hair growth and strengthens hair. In three months, hair gains up to 4 cm thanks to its formula enriched with Creatine and ceramides.

This mask protects the hair fiber from root to tip. Three amino acids also reinforce hair structure, sealing the cuticle on the surface. This complex is combined with maleic acid: it penetrates to the heart of the fiber, making it stronger and more resistant to external aggressions. The effects are rapidly visible, with 78% fewer split ends and 99% less breakage. Hair is longer, but also softer, shinier and more supple.
