A daily leave-in for men whose hair is thinning or breaking
Kérastase Genesis Homme Anti Hair-Fall Fortifying Serum is a daily leave-in scalp serum for men with weakened, thinning hair. Used as a six-week course, it combines Aminexil, which helps anchor the hair in the scalp, with creatine to reinforce the fibre and ginger root to stimulate the scalp. The result is less hair fall from breakage and fuller-looking hair, with a soothed, fresher scalp.
How it works
A light, liquid serum applied with a dropper straight onto the scalp. It dries fast, leaves no grease and needs no rinsing.
Who it suits
- Men noticing more hair fall from breakage
- Fine or weakened hair that looks less dense
- Scalps that feel tight or itchy
Worth knowing before you buy: the serum contains denatured alcohol and fragrance, so it can sting a freshly shaved or irritated scalp.
How long one bottle lasts
At four doses a day, the 90ml bottle covers the full six-week course.
