Clinical efficacy and safety of low-dose oral minoxidil versus topical solution in the improvement of androgenetic alopecia: A randomized controlled trial.

Although topical minoxidil has a better overall therapeutic effect than 1 mg oral minoxidil, the difference between the two groups was not significant. Therefore, 1 mg oral minoxidil may be as effective and safe as standard topical minoxidil in female and male pattern hair loss.
