Yes, a female can naturally grow a beard. Though it is not as common as it is for males, some females do have the ability to grow beards. The condition is called hirsutism and occurs when there is an excess of male hormones (androgens) in the body. Hirsutism can be caused by a variety of things, including polycystic ovarian syndrome, certain medications, and obesity. While it is possible to treat hirsutism with medication, many women choose to simply embrace their facial hair and rock a bearded look!
