Dry & Itchy Scalp Care from As I Am. I researched for shampoo to help with my dry scalp and this one kept coming up. High quality product. Great lather. Has olive oil and tea tree oil. You will feel tingles due to the tea tree oil. It breaks up the dead skin but leaves the hair feeling soft and moisturized. It is sulfate free which is rare in a “dandruff” treatment. It’s also safe for color or chemically treated hair. I did notice my color fade at all. Not matter what type hair you have, you can use this shampoo. It does have a strong smell because of the tea tree oil, but it’s not horrible.
