The Kérastase Genesis Défense Thermique isn’t just a heat protectant — it’s hair armor. I spray it on before blow-drying or straightening, and my hair looks like glass — smooth, frizz-free, and so soft I can’t stop touching it.It smells absolutely divine (that signature Kérastase scent that lasts all day 😍) and doesn’t leave any stickiness or residue. My ends used to look fried after heat styling, but now they stay healthy and shiny — like I just walked out of a salon.It’s lightweight, nourishing, and seriously protective — my hair feels stronger with every use. Whether you use heat daily or just occasionally, this spray is a must-have in your routine.
