Pattern baldness is the type of hair loss that doctors most often see. It affects both men and women though it is more common in men. Pattern baldness, or androgenetic alopecia, can begin in the teens or twenties and becomes more noticeable with age for men. It affects about 35 million men in the United States. However, more than 50 percent of men over the age of 50 experience some degree of hair loss. In women, pattern baldness appears most often after menopause.
