My one true lifesaver is Malibu C Crystal Gel Treatment and Un-Do-Goo Shampoo. Whenever I have residual fashion colors in hair, a mix of Crystal Gel Treatment then thorough shampooing with Un-Do-Goo never fails to remove the last bit of color, revealing a fresh canvas to fill with whatever color desired. Malibu C Color Wellness and Scalp Wellness Shampoos and Conditioners smell wonderful, also!
