Avodart to Propecia? Has anyone done this?

[konfusion]

if those shedded/damaged mintarised hairs were NOT in thier last cycle of growth users can expect those hairs to regenerate i.e thicken up/grow back because the true cause of baldness has been reduced...but if they were they are gone into vellus/resting phase and propecia alone will not revive them.

according to this logic if they are on their last cycle they will still be gone if you don't use it, so what's the catch? a couple of more months with baby hairs that doesn't mean anything cosmetically?
