I bought the product as I went through a period of itchy and reaching scalp. I have to say that it somehow helps fixing the problem, but gee.. your hair is to be washed afterwards, as it builds up like crazy. You have to apply on clean hair/scalp, therefore you wash it before. When you're done with the job, your hair is greasy again. So basically it must be used at night or when you can stay home with a hair mess. As a note, i have fine, volumeless hair so maybe this works better with people blessed with stronger coarser hair....
