A daily scalp serum for hair that sheds and snaps
Kérastase Genesis Anti Hair-Fall Fortifying Serum is a daily leave-in scalp serum for weakened hair that tends to fall out from breakage. Its gel texture works at the root: Aminexil helps limit hair fall by keeping the tissue around the follicle supple, caffeine supports the scalp and ginger root extract helps protect it from daily stress. It also soothes the discomfort that often comes with shedding, such as itching or tightness, so the scalp stays in a balanced state for stronger, fuller-looking hair.
The texture
A light, fresh gel that you apply straight onto the scalp in sections. It does not weigh hair down or leave it greasy, so you can style as usual straight afterwards. It has the recognisable Kérastase scent.
Who it suits
- Women whose hair sheds more than usual, including seasonal shedding
- Fine or weakened hair that breaks easily
- Irritated or uncomfortable scalps
- Anyone wanting a daily step that fits between washes
Worth knowing before you buy: the formula contains alcohol and fragrance, so it may sting a freshly scratched or very sensitive scalp. It helps reduce hair fall from breakage; it does not make new hair grow. There is a separate Genesis Homme version for men.
