Oral Minoxidil

I was reading an article about the efficacy of platelet rich plasma one day and someone said that -

with small studies or samples we don’t know if it would work for everybody.)

And if i recall correct then studies are categorized as ‘small’ when the number of participants in the study go below 300. Now to what i want to know, can i now start taking oral min and say i have 80 or 90% chance of regrowth or is it necessary to have larger studies to know that?.

Your biggest hurdle is to find a doctor who is willing to prescribe oral minox for hair loss.

Back in the days, many many years ago , people were talking about using oral minox + oral spiro + oral finas = the magic bullet to stop hair loss and regrow hair. Still, the problem is to find a doctor who is willing to put you on these meds.
