A buttery rich hair mask treatment that acts as an emergency bandage for extremely damaged, over-heated and chemically processed hair, the Kérastase Resistance Therapiste Masque Duo drenches hair in moisture, leaving locks feeling soft and weightless, fortified from within and protected from further breakage. Harnessing the powers of Kérastase’s Fibra-Kap™ complex, this luxurious mask is jam-packed with Amino Acids, SP94 Peptide and a Wheat Protein to help rebuild the hair, fight any damage at the follicles and encourage more elasticity. Fibra-Kap™ works to recoup any Keratin Associated Proteins that have been lost in the hair, strengthening the hair shaft and revitalising the surface. Providing long-lasting nourishment, Wheat Protein repairs and fortifies severely damaged hair giving it the intensive moisture it needs to restore its health. Resurrection Sap further works to revive parched and brittle hair, effectively ‘bringing it back to life’ whilst smoothing and hydrating it. Locks are left transformed; softer, lightweight and repaired from deep within. Apply to shampoo and towel-dried hair, massaging through the lengths and ends and leaving on for 5 minutes before rinsing thoroughly.
