Anna Donna Every Color Treatment can be used to strengthen hair color after the hair dye. After shampoo, use this easy conditioning treatment for simple, one-step hair color. You can use it every day without damaging your hair or scalp. One use provides a subtle, natural shade, while continued use gradually deepens the color. Adjust how often you use to maintain your preferred color. You can easily remove any color remaining on your bare hands or skin with soap.
