Genesis Défense Thermique is a leave-in spray from Kérastase's Genesis line, aimed at hair that sheds and breaks, especially weakened, fine or color-treated hair. It combines heat protection with antioxidant and protein care, and it is meant to be sprayed on damp or dry hair before styling. Compared with heavier anti-hair-loss leave-ins, it is light and non-greasy, so it suits daily blow-drying and heat styling. It is a cosmetic treatment, not a medical one, and it works best alongside the rest of the Genesis routine.
