Kérastase Genesis Bain Hydra-Fortifiant is a lightweight strengthening shampoo for fine to oily hair that's prone to breakage. It cleanses gently while fortifying each strand from root to tip, strengthened by Ginger Root and Edelweiss native cells — so hair breaks less and feels stronger, lighter and fresher for longer.

Benefits
  • Less breakage — fortifies fragile strands to reduce the hair fall caused by breakage.
  • Lightweight cleanse — lifts oil and build-up without stripping or weighing hair down.
  • Fresh from root to tip — keeps fine hair and quick-to-oil roots feeling clean for longer.
  • Softer, easier to manage — smoother to detangle and style day to day.
How to use
  1. Apply to wet hair and massage through the scalp and lengths.
  2. Rinse, and repeat if needed.
  3. Follow with a Genesis conditioner, and use at every wash.
Who it's for

Best for fine to normal hair that turns oily at the roots and feels weakened or prone to falling through breakage. If your hair runs dry, reach for the richer Nutri-Fortifiant instead. Explore the full Kérastase range to build your routine.
