When hair is damaged, its molecular structure, composed of peptides, is compromised. Hair breaks, becomes too elastic, with no movement.But most peptides are too big to be reinjected into the fibre, making damage almost irreversible.

For the first time, L’Oréal Advanced Research achieved to break down peptides, to inject their components separately into the fibre4.Once inside, they reform & rebuild the molecular structure of the hair1.For all damaged hair textures, color-treated, lightened & natural hair.
