I was super excited to try this hair and scalp treatment. I have been having dry scalp issues since winter and I really thought this would be my solution. Unfortunately, even if you use a pin-sized portion of this product, it leaves your entire head of hair really greasy. No joke, I had to wash my hair three times after using this before it even looked normal again, and surprisingly, it left me with EVEN MORE flakes! I just don't get it. I'm not sure who this product would be effective on, I was disappointed.
