I used this on my hair and I didn't see a difference. However, I'd have to buy three or four of these full-size containers to be able to use on my hair for two weeks. I have very thick hair and my scalp is always dry (but with no flakes). The product felt like it left my hair oily and gross. The packaging also broke. I took out the sprig and the pump and just scooped the product out into my hands to use it. Too oily, not enough product, poor packaging. I won't be buying this again. I'd much rather have a dry, itchy scalp than deal wight he hassle of this product.
