Topical minoxidil (Rogaine) appears to be effective for enhancing beards and stimulating hair growth in the lower facial region, although few studies have been reported. One trial found a significant improvement in beard growth as assessed by photography, as well as significant improvements in facial hair count after 16 weeks of twice daily topical minoxidil 3%. The participants in the trial also reported noticing that their beard growth had improved. There was no difference noted between the thickness of beard hairs in those who applied minoxidil compared to those who applied a placebo (an inactive) treatment.
