BACKGROUND: Topical minoxidil is the recommended first-line pharmacologic treatment for male and female pattern hair loss. However, low-dose oral minoxidil has been used off-label with good clinical efficacy and safety.
AIM: To compare the effectiveness and safety of topical minoxidil as a first-choice treatment of androgenetic alopecia versus 1 mg daily oral minoxidil.
METHOD: Sixty-five AGA patients were randomly allocated to receive either 5% topical solution or 1 mg/day oral minoxidil for 6 months. Treatment efficacy was evaluated by measuring hair diameter, photographic assessment, and patient self-assessment questionnaires. The safety of treatment was checked through history taking and physical examination.
RESULTS: Both topical and oral minoxidil groups showed significant improvement in hair diameter after 6 months of treatment (p < 0.001). However, there was no significant difference between the two groups. The photographic assessment demonstrated a significant improvement in hair density in the topical minoxidil group in all marked points located at 12 cm (p = 0.025), 16 cm (p = 0.034), and 24 cm (p = 0.014) distance from the glabella but not in the oral minoxidil group. Nevertheless, the difference between the two groups was not significant. In each group, over 60% of patients expressed satisfaction with their treatments, and no significant difference was detected between the two groups.
CONCLUSION: 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.
