first of all hello to everyone.new to the forum. my query is this.i was on propecia for 3 years then finpecia for a further 5 years with a complete cessation of my male pattern baldness.i've recently started taking dutas 0.5 every other day with similar results.with a very slight regrowth.i am happy with my meds so far. i never experienced any shedding at all with any of my previous medications and as i wear my hair on a number 2 shave i'm worried that i will start shedding with minoxidil use(just started) there seems to be around a 50% shedding chance with minox. because i never shed with the other medications does it mean i won't shed with minox? any views/opinions welcomed.
