One United is a multi-benefit leave-in treatment built around Coconut Oil, Amodimethicone, and Redken's Cationic Complex, delivering 25 benefits across three categories: control, protection, and beauty. The Cationic Complex is designed to revitalize hair while reducing porosity and static, and Keracare technology contributes repair support, color protection, and a thermo-protective action.
Coconut Oil nourishes, softens, and adds shine, while Polyquaternium-37 and Behentrimonium Chloride act as conditioning agents that detangle and help prevent breakage from brushing. The lightweight formula is designed not to weigh hair down, priming it for styling while helping guard against heat damage and external aggressors.
Suitable for all hair types and textures, including color-treated hair, One United is designed to be applied to towel-dried hair and left in, or used as a pre-styling primer before heat tools.
