When hair is damaged, its molecular structure — composed of peptides — is compromised. For the first time, L'Oréal Advanced Research achieved to decompose peptides and inject their components separately into the fiber. Once inside, they reform and rebuild the molecular structure of the hair.*

This patented leave-in mask, formulated with Peptide Bonder and 5 Amino Acids, repairs hair's macro-molecular structure. Hair is stronger with improved elasticity and movement. Repairs 2 years of damage in one use.*

The formula's lightweight texture instantly penetrates and restores strength for a natural touch. Hair is instantly smooth, shiny, healthy-looking and protected against external aggressions.

Heat protection up to 230°C / 450°F. Recommended for all damaged hair textures — color-treated, lightened and natural hair.
