While it is normal to lose some hair every day, when you begin to see bald patches or lots of thinning hair, you may be experiencing hair loss. The most common cause of hair loss is a medical condition called hereditary hair loss.
About 80 million men and women in the United States have this type of hair loss. Other names for this type of hair loss are: male-pattern baldness, female-pattern baldness and androgenic alopecia. Hereditary hair loss is often characterized by a receding hairline for men, and a widening part for women.
The causes of most hair loss can be stopped or treated.
