Alopecia Areata (AA) is understood to be an autoimmune condition. The immune system which normally protects the body from foreign invaders, such as viruses and bacteria, mistakenly attacks the hair follicles. This is what leads to hair loss. Alopecia Areata can typically start as one or more small patches on the scalp. The hair loss can remain patchy or can continue until all hair on the scalp is lost (Alopecia Totalis or AT). There is currently no known cure for alopecia. It can affect all ethnic groups and ages and occurs equally in both men and women. SMP is a great modern way of concealing Alopecia areata.
