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 fibre, making damage almost irreversible. Scientific discovery absolut repair molecular. Help repair molecular hair damage and restore hair's original 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. Innovative technology more than surface repair, it is inner molecular repair. This exclusive rinse off serum, highly concentrated with 2% peptides bonder 5 amino acids, rebuilds the hair molecular structure to restore its strength, elasticity and movement. Deep penetration inspired by ultra potent skincare serums, it goes beyond regular repair masks and deeply penetrates into the fibre to rebuild its molecular structure with no superficial coating. Instant transformation instantly, hair is visibly transformed shine and smoothness are dramatically improved. Professional formula its serum like texture is immediately absorbed into the fibre and provides molecular repair with no weigh down. Recommended for all damaged hair for all damaged hair textures, colour treated, lightened and natural hair. To use to be used instead of your regular mask. More concentrated and highly penetrating, it instantly transforms the inner part of the fibre. If needed, you can complement inner repair with surface coating with absolut repair mask. For optimal results, use the rinse off serum after absolut repair molecular shampoo and detangle hair for better serum absorption. Use on wet hair. Divide the hair into 2 sections. Press 2 3 pumps of the serum onto the hands. Distribute evenly onto one section from lengths to ends. Repeat on the other section. For very dry hair, apply from roots to ends. Work the serum through the hair between the palms of your hands for 1 to 2 minutes. No development time needed, instant action. Rinse thoroughly. For optimal results, follow with absolut repair molecular leave in mask.
