Query: Didn't notice a difference

I was hoping that based on the majority of excellent reviews I read, and other Jason products I use and love, that this one would work to eliminate my dandruff and itchy scalp, but it didn't. I used it according to the directions every other day for 10 days and although I had slightly less noticable itching, I still have dandruff. I was careful to gently massage my scalp and leave it on for the sufficient time in the shower. Maybe I didn't give it enough time, however, I noticed that several reviews said that it worked quickly for them. The smell is quite strong but it did not put me off, and I am picky about smell of products I wear. It just smells like tea tree oil to me, not too medicinal. So, unfortunately, I'm discouraged and was hoping for immediate results and will need to find another 'kind' natural product that does not test on animals.
