KERASTASE Résistance Masque Extentioniste Strengthening Hair Mask 200ml

Kérastase Résistance Masque Extentioniste is a 200ml strengthening mask for long, brittle hair and split ends. Kérastase formulates it with Creatine R and maleic acid, and says it works on bonds within the hair structure to improve strength and elasticity. It is silicone-based (amodimethicone) and has no sulfates.

How it works

Maleic acid and creatine are the repair actives Kérastase names. Cetearyl alcohol and cationic conditioners soften the lengths, and amodimethicone smooths and seals the cuticle against breakage.

Who it suits

Weak hair that breaks as it grows, and hair worn down by Cyprus sun, sea and chlorine.

What it will not do

• It will not make hair grow faster. It helps reduce breakage.
• It will not mend split ends. Only a trim removes them.
• It contains amodimethicone, isopropyl alcohol and fragrance allergens.

Good to know

Kérastase directs a hazelnut-sized amount on towel-dried lengths and ends, left for 5 minutes, then rinsed thoroughly.
