KÉRASTASE Genesis Strengthening Fondant Renforcateur Conditioner, 6.8 fl oz — Lightweight Detangling & Hydrating

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.

How do I use the Fondant Renforcateur for best effect?
