Evidence for supplemental treatments in androgenetic alopecia.

In 2014, a review was conducted on alternative treatments for androgenetic alopecia, given the incomplete efficacy and side effect profile of the only FDA-approved treatments at the time, topical minoxidil and finasteride. The review focused on the scientific evidence supporting the efficacy of biotin, caffeine, melatonin, a marine extract, and zinc as supplemental treatments. However, the document did not provide specific details or conclusions about the effectiveness of these alternative treatments.
