Alopecia Areata Causes.

Alopecia means hair loss (al-oh-PEE-shah), the hair falls out in round patches when a person has a medical condition called alopecia areata (ar-ee-AH-tah), the hair may fall on the scalp and on the body elsewhere.

Alopecia areata is a disease that can remain unnoticeable, causing hair to fall out in small patches, however, these patches can eventually connect and then become noticeable, this disease develops when hair follicles are attacked by the immune system, leading to hair loss.

Alopecia Areata

According to current evidence, alopecia areata is caused by an immune system abnormality that damages hair follicleas, this particular abnormality leads to autoimmunity, an immune system that is misguided and tends to attack its own body.

As a result, the immune system attacks the body’s specific tissues, in alopecia areata, the body’s own immune system attacks the hair follicles for unknown reasons and interferes with normal hair formation. Affected skin biopsies show immune lymphocytes penetrating the hair follicle bulb.

Occasionally, alopecia areata is associated with other autoimmune conditions, such as thyroid, vitiligo, lupus, rheumatoid arthritis, and ulcerative colitis.

It is unlikely that diagnosing or treating these diseases will affect the course of alopecia areata. Alopecia areata sometimes occurs within family members, suggesting a gene role.
