ntroducing Absolut Repair Molecular Serum, a groundbreaking solution by L'Oréal's Advanced Research to address the challenge of damaged hair. The molecular structure of hair, consisting of peptides, is often compromised when damaged, and traditional peptides are too large to effectively repair the fiber. With a groundbreaking scientific discovery, Absolut Repair Molecular Serum breaks down these peptides, allowing their components to be injected separately into the hair fiber, resulting in the reconstruction of the macromolecular structure. 250ML EXP. 12 months from opening date.
