Description

Extentioniste Mask Kérastase Extentioniste Mask is a repairing treatment for fragile, brittle long hair.
By penetrating the hair fiber, it restores shine and vitality to long hair.
Formulated with creatine R and maleic acid to boost hair fiber and add body.

Hair is repaired, supple and healthy.
Ideal for brittle, damaged lengths.
Active ingredients:
- Creatine R Complex: composed of creatine and ceramides that strengthen the fiber's internal structure, added to lipids that repair the hair cuticle.
The formula is enriched with maleic acid to strengthen and seal the cuticle.

How to use:
After Extentioniste shampoo, apply a very small amount of Masque to lengths and ends, to avoid weighing hair down.
Leave on for 5 minutes and rinse. Follow with Extentioniste Thermique leave-in cream.

Capacity: 200 ml

Kérastase Extentionist Mask
Kérastase Extentionist Mask is rated 3.0 out of 5 by 6.

Rated 1 out of 5 by from Very disappointed I have long, wavy, dry hair and had high hopes for this product after all the good reviews. Having used the masque twice now, I am bitterly disappointed with this product. It did nothing to address the dryness or brittleness of my hair and I felt I had to wash it again the next day when my regular conditioner keeps my hair feeling softer for longer. An expensive product which failed to deliver on its promising.

Rated 5 out of 5 by from Best conditioner I have ever used! My hair started getting brittle after the summer and the product fixed it completely! Very much worth the money!

Rated 5 out of 5 by from I love this Growing my hair out and this is a game changer. I leave it on for 20 mins then rinse off. My hair is so much stronger, glossier and more ‘alive’ at the ends, if that makes sense :)
