Several factors control hair growth on the face, including nutrition, genetics and hormones. Following a healthy lifestyle through exercise and good eating habits helps the body produce hair. In some instances, medical solutions, including testosterone therapy, exist to generate hair growth.
Facial hair growth varies immensely from person to person, and both men and women grow facial hair. Testosterone therapies help some patients boost hair growth. According to the Smithsonian Institution, some patients even have transplants to begin growing hair on the face. In order to perform this procedure, doctors must take hair follicles from the head and individually transplant them into the skin on the face.
