You're asking a hypothetical question that nobody can know the answer to.
Simlilar to this: Piacere - if I took Minoxidil for 3 days and then Propecia for 2.5 days, then clapped my hands, would my hairs grow at a different pace after 11 days?
I think the best response was Zeroes. Propecia will adjust your hormone levels and this will likely affect your hair. Even if its just a disruption of sorts. Minoxidil can affect growth phases and therefore shedding may occur. Yet another form of "disturbance" if anything. The rest is anyone's guess.
