The term “common baldness” usually means male-pattern hair loss. Male-pattern hair loss is the most common cause of hair loss in men. Men who have this type of hair loss usually have inherited the trait (hair follicles receptive to DHT bonding). 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 hair line and baldness on the top of the head.
