What is common baldness? The term “common baldness” usually means male-pattern baldness, or permanent-pattern baldness. Male-pattern baldness is the most common cause of hair loss in men. Men who have this type of hair loss usually have inherited the trait. Men who start losing their hair at an early age tend to develop more extensive baldness. In male-pattern baldness, hair loss typically results in a receding hairline and baldness on the top of the head. Women may develop female-pattern baldness. In this form of hair loss, the hair becomes thin over the entire scalp.
