“The most common cause of hair loss in both men and women is androgenetic alopecia, which is genetic pattern hair loss,” explains Dr. Michael B. Wolfeld, a board-certified plastic surgeon and an assistant clinical professor of plastic surgery at the Icahn School of Medicine at Mount Sinai Hospital in New York. The root cause of this type of hair loss is dihydrotestosterone (DHT), a byproduct of testosterone that shrinks certain hair follicles until they eventually stop producing hair.
