Genetics - male pattern baldness
The term "common baldness" usually means male 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 hair loss, hair loss typically results in a receding hair line 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.
The genetic causes of male pattern baldness and other common diseases of genetic hair loss are more complex than most people think. Researchers are using the latest tools, like gene chips, to find the genes that cause hair loss. Recent successes indicate that these techniques may one day be used to precisely target these genes with medication.
