Absolutely! Our Extra-Gentle Shampoo was formulated specifically with colour treated hair in mind. Our Extra-Gentle Shampoos have a lower pH to help lock in colour and are available in 3 different scents, including Sweet Pea, Citrus, and Unscented. Certain hair dyes (Henna) may be lost over time with frequent shampooing. Our Shampoo/Body Wash products are also safe to use on colour treated hair.
