I got to use this many times before this review so I can honestly say it works! It worked immediately but I wanted to see if it was one of those products that at first feels great at first use, then flops after. This shampoo is not like that. It works and it is consistent. It says to use 3 times a week I believe, but I would say 2-3 times in my case was just fine. I’ve spent so much money on shampoos for my scalp and the problem never went away. It would stay the same or get worse in some cases. Money literally down the drain. The price to me is worth it when you think of all the money you’d spend on other shampoos that will probably not work. It doesn’t have a perfume-y scent, and that might be why it works. The smell isn’t like your regular shampoos and threw me off at first but it’s a super clean smell and feeling. So glad I decided to give it a try. I didn’t want to spend the money for it to not work but it did!
