Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.

How is female hair loss treated? Minoxidil (Rogaine) 5% is the only topical medication approved by the FDA for female-pattern hair loss. The once daily use foam treatment regrows hair in 81% of the women who try it. Liquid options of 2% and 5% solutions are available over the counter.
