TLDR Low-dose oral minoxidil improved or stabilized hair loss in some patients, but higher doses may be needed for significant effects.

The study investigated the use of very low dose oral minoxidil (OM) as a monotherapy in the treatment of male androgenetic alopecia (AGA). The results showed improvement or stabilization in a percentage of individual patients for all parameters analyzed, but statistical analysis did not show a significant variation in the group as a whole. Adverse effects reported were pedal edema, hair shedding, and body hypertrichosis. The study suggests that higher doses of OM might be necessary to produce significant effects in men.

in Research 461 upvotes 8 months ago
