Product details

KÉRASTASE Genesis Strengthening Fondant Renforcateur is a lightweight conditioner that detangles, hydrates, and reinforces weakened hair to reduce breakage from brushing while adding body and shine.

This conditioner from the KÉRASTASE Genesis range is formulated for hair made fragile by heat styling and mechanical stress. It combines edelweiss native cells and ginger root to support fiber fortification and deliver immediate softness without weighing hair down. The texture is designed to spread easily through towel-dried lengths and rinse clean for a manageable finish.

How does this conditioner reduce hair breakage?

The formula targets weakened fiber with ingredients chosen to strengthen and smooth cuticles, helping hair resist the stresses of brushing. By improving detangling and reinforcing strands, it helps lower the likelihood of breakage during daily styling.

  • Contains edelweiss native cells to support fiber fortification
  • Ginger root helps reinforce hair against mechanical stress
  • Lightweight texture smooths cuticles for easier detangling
  • Designed to be used after shampoo as part of the Genesis routine

What results can I expect after using it?

After just one application hair feels softer, easier to comb, and displays improved surface shine. With regular use in combination with compatible Genesis shampoo and serum, hair appears stronger and shows less breakage from brushing.

  • Instant detangling for reduced mechanical damage
  • Noticeable hydration without heaviness
  • Added body and light reflective shine
  • Helps prevent split ends when used consistently

How do I use the Fondant Renforcateur for best effect?

Apply to shampooed, towel-dried hair focusing on mid-lengths and ends, leave on for 2–3 minutes, then rinse thoroughly. For best outcomes, pair with the Genesis shampoo and serum to target the causes of breakage and maintain strength over time.

  • Use after cleansing with a Genesis-compatible shampoo
  • Apply a small amount to damp lengths and ends
  • Allow 2–3 minutes of contact time before rinsing
  • Follow with styling products suited to your hair type

Will this conditioner weigh down normal to dry hair?

No—this Fondant Renforcateur is formulated to deliver moisture and softness while remaining lightweight. It adds volume and body rather than flattening hair, making it suitable for normal to dry weakened hair that needs reinforcement.

  • Light emollients hydrate without heavy residue
  • Designed to add body as it detangles
  • Rinses clean to preserve natural movement
  • Compatible with styling routines for added lift

Who is this for: KÉRASTASE Genesis Strengthening Fondant Renforcateur is intended for people with normal to dry hair weakened by heat styling, frequent brushing, or mechanical stress. If you want a salon-grade conditioner that detangles quickly, reinforces fiber integrity, and leaves hair more manageable with added body and shine, this product fits into a strength-focused haircare regimen.
