Color WOW Dream Filter

Color WOW Dream Filter Pre-shampoo Mineral Remover. The breakthrough Pre-Shampoo treatment filters out minerals, typically found in hard water, that could destroy the intensity and beauty of your hair. Traces of copper, iron, magnesium, calcium, chlorine and other elements that remain in your hair will warp your colour over time, making it look yellow, brassy, ashy green… dull, dark and dingy, depending on the mineral content.
