Answer : SCALP
Alopecia areata (AA) is the patchy loss of hair on the scalp or body. It can occur at any age and affects 1% of the population, most commonly children. The reasons for its development are not fully understood. Although not life threatening, the hair loss can be psychologically traumatic.
Scientists think AA is an autoimmune disease where white blood cells from the immune system attack hair follicles and keep them from producing hairs. Autoimmune disease occurs when a patient’s immune system mistakenly thinks that part of his or her own tissue is diseased. The tissue is then attacked. The end result depends on how effectively the tissue defends itself as it tries to grow back normally.
Usually, dermatologists diagnose AA by close examination of the scalp, and considering, then eliminating other hair loss causes. Typical AA starts as a smooth bald patch that suddenly appears. Some people feel a tingling sensation or very mild pain in the affected area. The scalp is the most commonly noticed area, but AA can form anywhere on the body: eyelashes, armpits, leg hairs, etc.
AA spreads out on the edges as it grows, with the hairs on the edges thinning out at the roots until they fall out. The stubble left at the edge is thin at the bottom and is said to look like an exclamation mark (!). As long as hair can be easily pulled out, the AA is active and further hair loss should be expected. More hair in the comb means more spots.
