What Is It?

KERASTASE Genesis Bain Hydra-Fortifiant Shampoo is a lightweight fortifying shampoo from the KERASTASE Genesis range, developed specifically for weakened hair prone to falling due to breakage.

It is particularly suited to fine or oily hair, where a strengthening shampoo needs to cleanse effectively without creating unnecessary weight.

The formula removes sebum, impurities and buildup from the scalp and hair while helping reinforce weakened strands and improve their resistance to breakage.

An important distinction for customers searching for "hair loss shampoo": Genesis Bain Hydra-Fortifiant is designed to address hair fall caused by breakage of weakened hair. It should not be presented as a medical treatment for hair loss or as a product that treats the underlying causes of hair loss.

The result:

Cleanse → Strengthen → Reduce Breakage → Improve Resilience → Soften
