Kérastase Genesis Serum Anti-Chute Fortifiant 90ml

Kérastase Genesis Serum Anti-Chute Fortifiant is a daily leave-in scalp serum for weakened hair that is prone to falling due to breakage. It helps reinforce and protect the scalp's natural barrier and is the leave-in step of the Kérastase Genesis routine.

What it does

Genesis Serum is designed to reinforce and protect the scalp's natural barrier and help prevent hair-fall caused by breakage. It is applied straight to the scalp and left in, so it keeps working after you have finished styling.

Who it suits

It suits anyone whose hair feels weaker and is shedding more than usual because strands are breaking. It sits alongside your shampoo and conditioner rather than replacing them. If you are losing hair suddenly or in patches, speak to your GP or a trichologist first, as that can have other causes.

How to use Kérastase Genesis Serum

1. Use once a day, in the morning or before bed.
2. Apply 3–4 pipettes to a dry or towel-dried scalp, working section by section.
3. Leave it in; do not rinse.

Kérastase recommends daily use over a six-week period. If the serum gets into your eyes, rinse immediately and thoroughly.
