When hair is damaged, its molecular structure made up of peptides breaks down. Most peptides, made up of amino acids and peptide binders, are too large to be re-injected, making damage of this magnitude almost irreversible. Scientific discovery, Absolut Repair Molecular. Repairs 2 years of damage in one application1. For the first time, L'Oréal Advanced Research has succeeded in breaking down the peptides and reinjecting their components separately into the fibre2. Once inside, they reform and rebuild the hair's molecular structure3. The Rinse-Off Serum is highly concentrated with 2% peptide binder + 5 amino acids. More than a surface repair, it rebuilds the hair's molecular structure3, restoring its strength, elasticity & movement4. Inspired by ultra-concentrated skincare Serums, the Serum goes beyond a classic mask and penetrates deep inside the fibre to rebuild its molecular structure3. Instantly, hair is visibly transformed: shine & softness are dramatically improved5. 1Instrume
