The Kérastase Resistance Therapiste Serum, with its double action, gives damaged hair a second chance at life. This outstanding serum is rich in amino acids, which are essential for delivering reparative properties to your hair in addition to improving individual strand texture. Its binding nature encourages hair growth and resurfacing. It also contains FIBRA-KAPTM, a unique formulation that works jointly with the amino acids to offer protection from thermo-induced damage for temperatures of up to 230C. This means you get to worry less about hair breakage. Hair ends are sealed, minimising split ends, and blow-drying happens twice as fast. Apply the Kérastase serum to washed and towel-dried hair. Massage it evenly onto the hair lengths and ends, then blow-dry and leave in. This will leave your hair well moisturised, conditioned, and healthy in appearance. The serum is ideal for thick, unruly hair or hair damaged by heat styling tools. It can be used to make finishing touches to dry hair or during the styling of wet hair.
