Why customers choose Origin Beauty

KÉRASTASE Genesis Strengthening Fondant Renforcateur is a lightweight fortifying conditioner that detangles, hydrates and helps reduce breakage for weakened, normal-to-dry hair.

This professional-grade conditioner combines edelweiss native cells and ginger root extract to support hair fiber resilience while delivering instant softness and manageable slip. Designed as part of the KÉRASTASE Genesis range, the formula targets hair weakened by brushing and heat styling without weighing strands down. It adds body and shine while making wet hair easier to detangle and style.

How does this conditioner make brushing easier?

The fondant creates immediate slip so combs and brushes glide through damp hair with less resistance, cutting down on pulling and stretch that cause breakage. In addition to smoothing the cuticle, the blend of active ingredients reinforces the fiber surface to better withstand mechanical stress from styling tools and grooming.

  • Instant detangling for reduced snagging during brushing
  • Fiber fortification helps hair resist breakage from mechanical stress
  • Lightweight formula that maintains natural movement and body

What ingredients deliver strengthening and moisture?

The formula pairs edelweiss native cells with ginger root extract: edelweiss supports fiber resilience while ginger root helps reinforce strands and improve manageability. Together they hydrate the hair shaft and add slip without creating heavy buildup, preserving volume for normal-to-dry hair types.

  • Edelweiss native cells: supports long-term fiber strength
  • Ginger root extract: fortifies weakened areas and aids detangling
  • Hydrating base: restores softness and visible shine

How should I use the conditioner for best results?

Apply to shampooed, towel-dried hair from mid-lengths to ends, leave on for 2–3 minutes, then rinse thoroughly. For maximum benefit, use with other KÉRASTASE Genesis products—shampoo and serum—to create a full-strengthening routine that targets breakage from brushing and heat styling.

  • Use after Genesis shampoo on damp hair
  • Leave 2–3 minutes to allow active ingredients to penetrate
  • Rinse and style as usual; pair with Genesis serum for added protection

Will it weigh my hair down or affect volume?

No—this conditioner is formulated to be lightweight while still delivering meaningful hydration and reinforcement. It softens and smooths without flattening hair, so you retain body and natural movement even after conditioning.

  • Light texture suitable for normal to dry weakened hair
  • Adds visible body and shine without heaviness
  • Fast-acting: noticeable slip for easier styling and less breakage

Who is this for: KÉRASTASE Genesis Strengthening Fondant Renforcateur is aimed at people with normal-to-dry hair that has become fragile from heat, styling or frequent brushing. It's ideal if you need an easy-rinse conditioner that immediately detangles, adds moisture and helps reinforce the hair fiber while preserving volume. Use it as part of a targeted regimen when breakage from mechanical stress or styling tools is a concern, and pair it with complementary Genesis shampoo and serum for best results.
