Abstract
Abstract The present invention relates to hair care compositions comprising chelants and methods for reducing oxidative hair damage. The compositions contribute to reducing the oxidative damage sustained by keratinous fibers such as human hair during bleaching, dyeing, perming or other oxidative treatments. The compositions according to the present invention also provide excellent color evenness and color fastness.
