Hi Craig.....As for regrowth if you get on minox and stay on it you should gradually get back those hairs previously lost due to quitting minox,also consider that.....it took a while for your hair to get in the "bad shape" its in long before your considered treatment.
So you have to allow ample time if not longer to "re-establish" those hairs due to the onslaught of MPB,so......be patient get you some Emu Oil apply it either before or mix it with minox(in a seperate container)prior to application!
As for Shampoo's dont sweat SLS's too much!Get some nizoral and if you can afford it get some "NANO"w/proxiphen-N
Good Luck........thinningnugget
