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 & 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 & Creatine which contains Amino Acids & 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 & fuller. The lightweight formula ensures hair can be combed through without any tangles that can cause further breakage & it also works by penetrating weak & brittle hair with curative molecules that noticeably refine the lengths. With the hair's fibres sealed & coated, the overall textures & appearance are more fluid, smooth & free of knots. The conditioner purifies & strengthens the hair whilst encouraging healthier new growth. Apply to freshly shampooed hair & rinse off thoroughly.
