Our Clarifying Rescue Treatment does not contain sulfates, but since it has not been tested extensively on keratin-treated hair, I would not recommend it. I would instead suggest our Gentle Shampoo, which also does not contain sulfates but is a great daily shampoo that is also silicone-free, paraben-free, phthalate-free and dye-free.
Hope this answers your question and thanks for your interest in our products. Remember, a good hair day can change the world!
