Kérastase Genesis Bain Hydra-Fortifier
Strengthening and Hydrating Shampoo for Weak or Fragile Hair
Kérastase Genesis Bain Hydra-Fortifier is a revitalizing shampoo specially formulated to gently cleanse, hydrate, and strengthen weak or fragile hair. Part of the acclaimed Genesis range, this shampoo focuses on reducing hair fall caused by breakage while improving softness, resilience, and overall hair health. It’s ideal for all hair types that need deep nourishment and reinforcement from root to tip.

What It Does
Kérastase Genesis Bain Hydra-Fortifier cleanses hair and scalp without stripping natural moisture. Its hydrating formula helps fortify the hair fiber, making strands feel stronger, smoother, and more resilient against daily stressors such as brushing, heat styling, and environmental damage. Over time, hair appears healthier, more manageable, and less prone to breakage.
How to Use
Apply a small amount of shampoo to wet hair and gently massage into a rich lather from roots to ends. Rinse thoroughly and follow with a conditioning treatment like Kérastase Genesis Fondant Renforçateur or a favourite mask. Use consistently for optimum strength, hydration, and improved hair texture.
