Current evidence suggests that alopecia areata is caused by an abnormality in the immune system. This particular abnormality leads to autoimmunity. As a result, the immune system attacks particular tissues of the body. In alopecia areata, for unknown reasons, the body's own immune system attacks the hair follicles and disrupts normal hair formation. Biopsies of affected skin show immune cells inside of the hair follicles where they are not normally present. What causes this is unknown. Alopecia areata is sometimes associated with other autoimmune conditions such as allergic disorders, thyroid disease, vitiligo, lupus, rheumatoid arthritis, and ulcerative colitis. Sometimes, alopecia areata occurs within family members, suggesting a role of genes and heredity.

Yes, heredity plays a role. In one out of Yes, heredity plays a role. In one out of five persons with alopecia areata, five persons with alopecia areata, someone else in the family also has it. someone else in the family also has it. Those who develop alopecia areata for Those who develop alopecia areata for the first time after the age of thirty years the first time after the age of thirty years have less likelihood that another family have less likelihood that another family member will have it. Those who develop member will have it. Those who develop their first patch of alopecia areata before their first patch of alopecia areata before the age of thirty have a higher possibility the age of thirty have a higher possibility that other family members will also have that other family members will also have it.it.

In alopecia totalis, immune system In alopecia totalis, immune system cells called white blood cells attack the cells called white blood cells attack the rapidly growing cells in the hair follicles rapidly growing cells in the hair follicles that make the hair. The affected hair that make the hair. The affected hair follicles become small and drastically follicles become small and drastically slow down hair production. Fortunately, slow down hair production. Fortunately, the stem cells that continually supply the stem cells that continually supply the follicle with new cells do not seem the follicle with new cells do not seem to be targeted. So the follicle always to be targeted. So the follicle always has the potential to regrow hair.has the potential to regrow hair.
