To care for color-treated hair, use a sulfate-free shampoo to avoid stripping the color. Look for “no residue shampoos” that won’t leave color-warping ingredients.
Follow with a conditioner that doesn’t contain oxidizing conditioning agents that will turn color brassy.
Limit heat styling, use heat protectants, and shield hair from environmental damage, such as chlorine or pollution by applying a leave-in conditioner or a styling product that includes UV protection.
Overall, look for hair products like the full Color Wow and Curl Wow ranges, that have banned all ingredients that could darken, dull or negatively impact hair color chemicals from every single formula.
