What is Alopecia Areata?
Alopecia areata, commonly known as alopecia, is an autoimmune disease that results in hair loss. Alopecia is caused when the body’s immune system attacks the cells in hair follicles, because it mistakenly perceives them as invaders. In most cases, hair falls out in only a few small, round patches but, in some cases, alopecia causes a total loss of hair on the scalp (alopecia areata totalis) or a complete loss of hair everywhere on the body (alopecia areata universalis).
Causes of Alopecia Areata
The precise causes of alopecia remain unknown. What is known is that the body’s white blood cells attack the growing cells in hair follicles. The new cells in the follicles, however, retain their potential to grow hair. It is suspected that a combination of genetic factors reacts to an environmental trigger, perhaps a virus, to bring on alopecia.
