DevaCurl NO-POO BLUE Anti-Brass Zero Lather Toning Cleanser designed for color-treated curls. Brassy orange tones can ruin a good curl day. Thats why we worked with our Devachan colorists to develop a blue-hued cleanser (blue counteracts orange) to tone that brass while gently cleansing. The non-lathering, conditioning formula with blue lotus flower and Smart Porosity Toning Technology helps equalize porosity for long-lasting, uniform toning. It leaves curls nourished, shiny, bouncy and vibrant. Now you can forget brass and turn up the sass!
