Topical minoxidil increased total and non-vellus hair counts compared with placebo in people with androgenetic alopecia.
Systematic review and random-effects meta-analysis of topical minoxidil trials. Minoxidil beat placebo for hair growth, and more users than placebo had greater hair growth on investigator (RR 2.28) and self (RR 1.56) assessment.
In men with androgenetic alopecia, 5% topical minoxidil regrew more hair than 2% minoxidil or placebo over 48 weeks.
Double-blind RCT, 393 men aged 18-49 applying 5% or 2% minoxidil or placebo twice daily for 48 weeks. 5% was superior on hair counts and patient and investigator ratings, with 45% more regrowth than 2%.
In women with female pattern hair loss, 5% topical minoxidil increased hair counts compared with placebo over 48 weeks.
Double-blind RCT, 381 women aged 18-49 applying 5% or 2% minoxidil or placebo twice daily for 48 weeks. 5% beat placebo on all three primary measures, including non-vellus hair count.
