Yes, Silk Touch Keratin treatment is safe for color-treated hair and can improve the condition of the hair, while enhancing smoothness and shine. If you choose to color your hair before getting the Silk Touch Keratin treatment, it is recommended to do so right away; however, if you opt to color your hair after the keratin treatment, it is advised to wait at least 2 weeks before applying any color treatments to ensure the best results and longevity of both the color and keratin treatment.
