Boost shine and banish split ends with Kerastase Resistance Masque Extentioniste, an intensive hair masque that nourishes brittle and damaged hair.

Enriched with Creatine R and Maleic Acid, the restorative formula helps to repair bonds within the hair structure to improve strength and elasticity.

The conditioning masque seals the cuticle to protect against further breakage, whilst moisture is replenished to the scalp for long-lasting hydration.

Expect visibly shiny, silky and reenergised results.
