Naturally strengthen the hair from roots to ends with Kérastase Resistance Fondant Extentioniste, a nourishing conditioner that eases the detangling process, seals the hair’s cuticles and purifies the scalp so it has a healthy environment to grow stronger hair. Enriched with Kérastase's exclusive Creatine R complex, a blend of potent Ceramide and Creatine which contains Amino Acids and Lipids to fortify the hair from inside out, this creamy conditioner helps smooth the surface of the hair for a silkier, softer texture. Whilst it stimulates the scalp to create a more healthy environment, it also seals the ends so hair has a more uniform appearance that looks bouncier and fuller. The lightweight formula ensures hair can be combed through without any tangles that can cause further breakage and it also works by penetrating weak and brittle hair with curative molecules that noticeably refine the lengths. With the hair's fibres sealed and coated, the overall textures and appearance are more fluid, smooth and free of knots. The conditioner purifies and strengthens the hair whilst encouraging healthier new growth. Apply to freshly shampooed hair and rinse off thoroughly.
