Hey, well finasteride does have the same effect I think.. It's basicly the same thing, just cheaper.
But personally I'm 22 and I take half a pill in the morning and another half of the pill at night.. so thats a whole pill in 1 day, and I notice no difference from now and before I was taking the pill.
I payed about 30 bucks for 5 slips, which includes about 12 pills on each slip.. it's way cheaper than propecia.. I dunno if its less effective or not though. This is why I take pictures so often and post them here, so other people can see if these medicines have results.
Nizoral is a shampoo, thickening+health shampoo I think. I don't use it.. yet..
The big 3 : minoxidil (rogain) Propecia (or finasteride) and Nizoral.. those 3 have been the tried and true so far for most people.
