Jason Dandruff Relief shampoo looked like it might be a way for me to have my once-weekly scalp treatment without submitting my system to whatever they put into Head & Shoulders. (Don't ask what that might be - I've never dared to read the label.)
One use of Jason's did nothing for my scalp, so I kept trying. Five days later I still couldn't notice a difference, and my hair was starting to look as though I was using a bar of Dial soap.
I'm back to Head & Shoulders once a week for now, but I'll keep looking for something better. This isn't it.
