I tried this because I read it was good for cleaning oily scalps if you leave it on for a while. I think it helps clean and calm my scalp somewhat more than most shampoos, but it’s not a miracle worker and it kind of weighs down my hair and makes it flatter, which is a drawback for me as I’m not really into the sleek look. Sadly I don’t think it helped my hair slow down from getting oily. I have pretty typical East Asian hair.
