My hair is color treated (although brown to a nicer shade of brown), and I use this product with no troubles. I don't use it often, however--maybe once or twice a month? (Only when I'm starting to notice product build-up, because this seriously gets your hair squeeky clean.) When I'm not using this product, I use Bb seaweed shampoo, which is really gentle yet cleansing, and has been good with my color treated hair.

I colored my hair from light brown to black and had the same concern but this shampoo is amazing. I usually use it once a week more if needed to remove styling products and it works great. Leaves hair soft and shiny.
