The Absolut Repair Molecular Leave-In from L'Oréal Professionnel Paris has been specifically developed for severely damaged hair. It repairs two years' worth of hair damage in just one application. Enriched with peptide bonds and five amino acids, it penetrates deep into the molecular hair structure and instantly transforms the hair. The lightweight texture of the formula quickly absorbs into the hair fiber, providing it with renewed strength. The hair shines, feels smooth, and is protected from external influences. Heat protection up to 230 °C. Strength, elasticity, and movement of the hair are restored. The result: strong, healthy-looking, and flowing hair.
