Formulation Deep Dive

Hair Gloss by OUAI is a high-performance in-shower treatment designed to enhance shine and hair health through a sophisticated silicone-in-water emulsion. The carrier system utilizes a blend of Dimethicone, Phenyl Trimethicone, and Dimethiconol for immediate cuticle smoothing, while Propanediol and Glycerin serve as humectants to manage moisture levels during the treatment process. Active performance is driven by a synergistic combination of Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate for deep hydration, Oryza Sativa (Rice) Seed Water for strengthening, and Hydrogenated Castor Oil/Sebacic Acid Copolymer to provide long-lasting surface repair and shine. The formulation is stabilized by an Acrylamidopropyltrimonium Chloride/Acrylates Copolymer network and a blend of thickening agents like Cellulose Gum, while a preservation system of Phenoxyethanol and Chlorphenesin ensures formula integrity.
