For those with damaged, porous, weak and brittle hair, the Kérastase Resistance Masque Extentioniste offers a nourishing remedy with its deeply conditioning and strand strengthening benefits designed to cure seasonal, environmental, chemical and heat damaged hair.

For hair that feels unconditioned and frazzled, this richly textured formula is enriched with Kérastase’s exclusive Creatine R complex, a blend of Ceramide and Creatine that encourages the hair’s cuticle to stay flat whilst improving elasticity and the ability for hair to retain moisture. Particularly beneficial to brittle hair, the complex is incredibly nourishing, helping to eliminate frizz and stop moisture escaping through the cuticle. Further infused with Acid Maleic, the mask seals the flattened cuticle with a coating that provides consistency from root to tip. This encourages natural shine and a healthier appearance to the hair. Improving the flexibility and strength of the hair, it also provides an intense condition so that hair feels lightweight and more manageable.

Apply to freshly washed and towel-dried hair using a hazelnut-sized quantity, running it through the lengths and ends. Leave on for 5 minutes before rinsing out.
