[SCIENTIFIC RESPONSE - REPLACEMENT AT THE MOLECULAR LEVEL] When the hair is damaged, the molecular structure of the hair, made up of peptides, is weakened. The majority of peptides are too large to be reintroduced into the hair fibres and this makes the damage almost irreversible. A scientific discovery - Absolut Repair Molecular Heals two years of damage in one application*. For the first time, L'Oréal Advanced Research has developed a process to break down the peptides to deliver the peptide components separately into the hair fibres**. Once inside the hair fibres, they restore and rebuild the molecular structure of the hair***. [PATENTED TECHNOLOGY] This patented shampoo contains a peptide-binding compound and five amino acids that repair the macromolecular structure of the hair*. The result is stronger, conditioned hair that is more elastic, more flexible**** and 86% smoother*****. [PROFESSIONAL FORMULA] Nourishing and luxurious in consistency, this sulfate-free shampoo creates a rich lather that cleanses, eliminates tangles and deeply conditions hair. [RECOMMENDED FOR ALL DAMAGED HAIR] For all damaged hair textures, coloured, bleached and untreated hair.
