As a gentle fortifying shampoo from Kérastase, Genesis Bain Nutri-Fortifiant targets weakened, thinning hair to cleanse without stripping. It has a creamy lather that smooths strands and adds resilience, suited to fine to medium hair types seeking strength and manageability. Fragrance levels are moderate, and the formula feels nourishing rather than heavy—appropriate for those looking to improve hair density and reduce breakage over time.
