Kérastase Genesis Fondant Renforçateur is a strengthening rinse-out conditioner for hair that's prone to breakage. Fortified with Ginger Root and Edelweiss native cells, it detangles and reinforces weakened strands in one step — easing the friction during combing that is itself a major cause of breakage.

Benefits
  • Less breakage — eases detangling to limit friction-related hair fall.
  • Strengthens strands — reinforces the fibre for more resilient hair.
  • Nourishes without weight — softness and shine, never heavy.
  • Easier to manage — smoother, simpler to style.
How to use
  1. After shampooing, apply to mid-lengths and ends, avoiding the roots.
  2. Leave for 1–3 minutes.
  3. Rinse thoroughly, and use after every Genesis shampoo.
