Does anyone have any experience with liquid duta?

I'm thinking of adding it to my current regimen of oral duta, Nizoral, and minox. I have a respected source for it and am thinking of using it to speed up regrowth/progress and possibly use it in long-term maintenance as a replacement for RU (especially if someone can provide evidence that it is stronger than RU). My only concern is this: Would applying it to the head increase the likelihood of brain fog? I know oral duta can cause this and that the liquid is just going to absorb systemically anyway, but would applying it so close to the brain have any affect on the likelihood of this occurring?
