L’Oréal Professionnel Serie Expert Absolut Repair Molecular Rinse-Off Serum

Repair hair beyond the surface with L’Oréal Professionnel Serie Expert Absolut Repair Molecular Rinse-Off Serum, an innovative professional rinse-off treatment designed to rebuild the hair’s molecular structure from within. Powered by a patented Peptides Bonder + 5 Amino Acids technology, this lightweight serum penetrates deeply into the hair fiber to restore strength, elasticity, and movement, helping reverse up to 2 years of hair damage when used as part of the Absolut Repair Molecular routine. 

Unlike traditional hair masks that mainly coat the hair surface, this rinse-off serum works at the molecular level to help rebuild compromised hair fibers caused by coloring, bleaching, heat styling, and environmental damage.
