Causes of Alopecia #1: Autoimmune Disease
Alopecia is an autoimmune disease. This means that the immune system attacks the hair follicles, mistaking it for a foreign invader that it would normally defend the body against. When the immune system attacks the hair follicles, they stop growing hair and cause hair loss.
However, it remains unknown what causes the immune system to react in such a way because the triggers remain unknown. What is known is that people who have a family history of autoimmune diseases are more at risk of developing alopecia areata.
