Regenerating hair care that gently yet effectively detangles hair without breakage and provides a uniform silky effect. The lightweight creamy Kérastase Resistance Fondant Extentioniste conditioner is enriched with Creatine R, an active complex designed to increase strength and elasticity, and maleic acid, which reinforces the hair fibre and ensures an even surface. The quality of hair lengths is visibly improved, while the hair fibre is sealed, coated and regenerated for a smooth, knot-free feel.
