Give badly damaged hair the support and protection it deserves with this Kérastase Resistance Therepiste Serum 30ml Duo, a sophisticated formula designed to nourish, repair and shield against damage. Providing up to 230°C of protection against heat treatments from curling to blow-drying, this intensive treatment aims to make your locks look fabulous and keep them that way. If you have damaged hair due to excessive styling, sun damage or exposure to environmental pollutants, this sumptuous cream will get to work using its trademarked FIBRA-KAP™ formula and a complex of amino acids to repair split ends, smooth out the surface of hair strands and reduce breakage. It seals each individual hair fibre to prevent further damage, locking in nutritious oils and enhancing shine. Perfect for thick hair where other treatments are not enough, this cream smooths and softens each strand so that they slide over each other like silk. It frees up matted hair, detangles and leaves your locks soft and manageable. Suitable for use on damp or dry hair, it can be topped up throughout the day for a powerful effect.
