is there a scientific method or experiment to

distinguish between a minoxidil shed and just norwooding quicker?

i've been on minox since mid may. i've grown some small hairs between my temples and eyebrows (ogre) that always needs shaving, but on one side i've lost more (have always had asymmetric hair loss with one side balding and the other pretty much intact). i thought i caught it very early, but now i don't knkw whether it's the shed or just the reaper claiming me quicker
