When hair is damaged, its molecular structure, composed of peptides, is compromised. Hair breaks and 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 was able to decompose peptides and inject their components separately into the fibre. 

Once inside, they reform & rebuild the molecular structure of the hair.

For all damaged hair textures, colour-treated, lightened & natural hair.
