Hair Loss
The medical term for hair loss is alopecia. The most common type is pattern baldness (androgenetic alopecia). It accounts for about 95 percent of hair loss from the scalp. It's typically permanent and can be attributed to heredity. Another type of alopecia, alopecia areata, can be temporary. It can involve hair loss on your scalp or your body. Its specific cause is unknown.
