Synopsis The peptide-based molecular structure of hair is weakened by damage. Hair snaps, gets too pliable, and becomes immobile. However, the majority of peptides are too large to be reinjected into the fiber, rendering the damage nearly irreparable. L'Oréal Advanced Research successfully broke down peptides and injected each of their constituent parts into the fiber2 for the first time. Once inside, they reconstruct and reform the hair's molecular structure. For color-treated, lightened, and natural hair, as well as all damaged hair textures. technology covered by patents This unique shampoo, which is sulfate-free and has a luxurious texture that transforms into a rich foam, cleans, detangles hair, and provides a high level of care. It is made with peptide bonder and five amino acids, which repairs the macro-molecular structure of hair1. In addition to increased elasticity, movement, and + 86% smoothness, hair is now stronger and more nourished. 3. Guidelines
