The Kérastase Resistance Therepiste Serum is designed to nurture damaged hair. With a complex formula, it hydrates the fibre and conditions it, improving its overall structure. It creates more voluminous hair, making it healthy and strong. This binding serum contains the unique FIBRA-KAP formula that reactivates the synthesis of KAPs which are missing in damaged, heat-treated hair. The formula includes 6 essential amino acids and wheat protein hydrolat that nourish split ends and seal them to keep the fibre strong and resilient. Reinforcing the cuticle, it reduces the chance of breakage and tames thick, frizzy hair, especially during periods of increased humidity. Making it easier to stylise unruly locks, this rich serum works to protect tresses when using heat styling tools (up to 230 degrees). It also speeds up blow-drying and gives hair a silky, smooth finish. Applied to towel-dried hair, this leave-in product can also be used on dry hair, making it soft and shiny. With regular use, it prevents split ends and guarantees healthier hair.
