A leave-in spray from Kérastase's Genesis line, aimed at weakened hair that breaks and sheds. It combines heat protection with detangling, anti-frizz and a light thickening effect, and it is sulfate-free. Compared with heavier anti-hair-loss serums and ampoules, it is a lightweight daily step that also shields hair from styling tools. It suits fine or fragile hair that tangles easily and is styled with heat; those wanting a concentrated scalp treatment should look elsewhere.

Owners of fine, fragile hair tend to like how it detangles and protects during heat styling without weighing hair down. Some find it sticky or stiff when they use too much, and those expecting a real anti-shedding treatment say the effect is modest.
Kérastase Genesis Heat Protecting Leave-In Treatment is a spray for weakened hair. It is a leave-in formula, so it stays in the hair after application.
The formula is sulfate-free and contains protein. It nourishes, detangles, thickens and helps control frizz. It also protects hair from heat styling and helps prevent hair loss.
