[SCIENTIFIC DISCOVERY - MOLECULAR REPAIR] When hair is damaged, its molecular structure, composed of peptides, is compromised. But most peptides are too big to be reinjected into the fiber, making damage almost irreversible. Scientific discovery – Absolut Repair Molecular. For the first time, L’Oréal Advanced Research achieved to decompose peptides, to inject their components separately into the fiber*. Once inside, they reform & rebuild the molecular structure of the hair**. [PATENTED TECHNOLOGY] This patented leave-in mask, formulated with Peptides bonder + 5 Amino acid, repairs hair macro-molecular structure*. Hair is stronger with improved elasticity, movement****. [PROFESSIONAL FORMULA] The formula’s lightweight texture instantly penetrates and restores strength. Natural touch.
