About the Product

What it is: A patented molecular repair leave-in mask from L'Oréal Professionnel, formulated with a peptide binder and 5 amino acids to repair the macro-molecular structure of damaged hair. When hair is damaged, its molecular structure made up of peptides breaks down — most peptides are too large to be re-injected, making damage of this magnitude almost irreversible. For the first time, L'Oréal Advanced Research has succeeded in breaking down the peptides and reinjecting their components separately into the hair fiber, where they reform and rebuild the hair's molecular structure. Repairs 2 years of damage in one application. Hair becomes stronger with improved elasticity and movement — instantly soft, shiny, healthy, and protected from external damage. Thermo-protective: protects hair from heat up to 230°C.

Why It Works — Key Ingredients:

Peptide Binder and 5 Amino Acids (Arginine, Glycine, Serine, Tyrosine, Glutamic Acid): L'Oréal Professionnel's patented molecular repair complex that breaks down peptides and reinjects their components separately into the hair fiber — where they reform and rebuild the hair's macro-molecular structure, repairing 2 years of damage in one application and making hair stronger with improved elasticity and movement.

Amodimethicone: A conditioning silicone active that smooths and protects the hair cuticle — leaving damaged hair instantly soft, shiny, and protected from external damage and heat up to 230°C.

Polyquaternium-4 and Hydroxypropyl Guar: Film-forming and conditioning actives that coat and protect the hair fiber — contributing to the formula's thermo-protective, strengthening, and natural-feel performance for damaged hair.
