L'Oreal Professionnel Serie Expert Absolut Repair Molecular Leave-In Mask (100ml) is a scientific breakthrough in hair repair, providing up to 97% more hair strength and designed specifically for all damaged hair textures, including colour-treated, lightened, and natural hair. When hair is damaged, its molecular structure, which is composed of peptides, is compromised. Unfortunately, most peptides are too large to be reinjected into the fibre, traditionally making damage nearly irreversible. However, the Absolut Repair Molecular introduces a novel approach. For the very first time, L'Oreal's Advanced Research team has successfully managed to decompose peptides, enabling the separate injection of their components into the fibre. Once inside, they reform and rebuild the molecular structure of the hair, enhancing its strength and restoring its original qualities.

This patented leave-in mask is formulated with Peptides Bonder + 5 Amino Acids, diligently working to repair the hair's macro-molecular structure. Not only does hair become stronger, but it also gains improved elasticity and movement, ensuring it looks and feels healthier. Furthermore, its lightweight texture instantly penetrates to restore strength while maintaining a natural feel. The results? Hair that is instantly smooth, shiny, and healthy-looking, protected against external aggressions, and has heat protection up to 230°C/450°F.
