Kerastase's Genesis - Defense Thermique Heat Protecting Spray strengthens and revitalizes hair by significantly reducing breakage. Enriched with Edelweiss Native Cells and Ginger Root, this premium formula infuses deep hydration and essential nourishment into each strand, effectively reducing hair fall up to 99%.
Offering thermal protection up to 430°F, this creamy fluid achieves a smooth, frizz-free finish during styling. It gently detangles while fortifying hair, forming a protective barrier against heat and environmental stressors. Free from sulfates, this blow-dry essential not only offers a sleek and polished appearance but also ensures hair remains strong and healthy-looking after every use.
In case of contact with eyes, rinse them immediately and thoroughly.
