hello,iam using mioxidil for almost 4 months and i have not seen any regrowth.i just want to ask that on the leaflet that comes with minoxidil it is written that minoxidil is poorly absorbed in scalp and "local abrasion or dermatitis may theoretically increase systemic absorption" so what does it mean?how can i enhance its absorption what does it mean by local abrassion?how can i do local abrassion?
