The REPAIR mask deeply repairs hair from mid-lengths to ends, immediately restoring and consolidating damaged and brittle hair. At the heart of the formula is a new biomimetic complex, Keratine A18+, derived from plant research: a keratin composed of 18 enhanced amino acids that act as an intra-fiber filler to recreate the substance at the heart of the hair and restore damaged fibers. Sourced from black oats and lupine, this amino acid-infused plant keratin guarantees the resilience of naturally healthy, radiant hair. Thanks to the white mallow extract, hair is twice as shiny. No silicones, no sulfates.
