It's pretty cheap but kind of a bitch to put on because I have to dab a little on my fingers, separate the hair to get at the scalp, and then rub it in. I don't have any bald spots but I'm starting to notice some shedding and thinning on top. I just put it on and then do some chore, usually getting my vits/supps ready for the next day in little baggies and the protein drinks I take to work (the trouble we have to go through), and by then about 10 minutes have past and I hit the shower. After I use the minox but just recently (2 days ago) started adding the spiro. Reading the reference thread I'll probably get the minox/AA combo on my next order. I want to hit this hard before things get out of hand.
