Yes, it is safe for keratin treated and chemically treated (permed) hair. We have had many of our customers tell us that it has helped decrease or eliminate their itchy or flaking (dandruff) scalp. Though we primarily advertise the product toward women, it works just as well for men. We have many families who use our argan oil shampoo and conditioner set. If you have any other questions now or after you begin to use our products, please feel free to reach out to us email@example.com.
