Kérastase Genesis Serum Anti-Chute Fortifiant is a leave-in scalp and hair serum built around niacinamide and caffeine, sold in a 3.04 fl oz bottle with a pipette. It is aimed at women worried about shedding and thinning, especially hair that breaks or falls with brushing and styling. The formula is silicone-free and also claims anti-pollution, soothing and strengthening benefits. It sits in Kérastase's premium Genesis line, so it competes with pharmacy and drugstore caffeine and aminexil serums on formulation and feel rather than on volume. Ratings average about 4.1 out of 5, with users generally positive on how it makes hair feel and more divided on visible regrowth.
