When hair is damaged, its molecular structure, composed of peptides, is compromised. But most peptides are too big to be reinjected into the fibre, making damage almost irreversible. Scientific discovery - Absolut Repair Molecular. Up to 97% more hair strength. For the first time, L'Oreal's Advanced Research team successfully managed to decompose peptides, to inject their components separately into the fibre**. Once inside, they reform and rebuild the molecular structure of the hair***. [PATENTED TECHNOLOGY] This patented leave-in mask, formulated with Peptides bonder + 5 Amino acid, repairs the hair's macro-molecular structure*. Hair is stronger with improved elasticity and movement. [PROFESSIONAL FORMULA] The formula's lightweight texture instantly penetrates and restores strength. Hair has a natural feel.
