L'Oréal Professionnel Absolut Repair Molecular Rinse-Off Mask

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 fiber, making damage almost irreversible. This professional hair mask contains bond-building peptides that penetrate beyond the surface to address hair damage at the deepest molecular level.
