Thinning Hair started rogaine now shedding

[badincite]

My hair's been starting to thin for a few years now I've tired a few things Propecia which made me feel not quite right so I stopped, Liquid Minoxidil which was to messy. Now I picked up some rogaine foam 5% and I've been using it for about 3-4 weeks twice a day and now my hairs thinning quicker. I see where people say that's a good thing but not necessarily for me is there anything else I can use to slow the shedding Nizoral? Maybe cut back to once a day I don't care if it takes longer to regrow I really just wanted to maintain at least what I have.
