Alopecia Areata

Definition: Alopecia Areata (AA) is an autoimmune disease that causes hair loss in patches, ranging from small, round bald spots to complete hair loss from the scalp (alopecia totalis) or the entire body (alopecia universalis). It’s not contagious and can affect people of any age, gender, or race.

Cause: The exact cause of Alopecia Areata is unknown, but it’s believed to be an autoimmune response where the body’s immune system mistakenly attacks hair follicles, leading to hair loss.

History: Alopecia Areata has been recognized for centuries. Descriptions of the condition can be found in ancient medical texts. While the understanding of the underlying cause has evolved, the characteristic patchy hair loss remains its hallmark.

Treatment: There is no permanent cure for Alopecia Areata. However, several treatments can help stimulate hair growth and promote regrowth. These include:
– Corticosteroid injections or creams
– Immunotherapy medications
– Minoxidil (topical medication)
– Phototherapy (ultraviolet light therapy)
The success of treatment can vary depending on the severity and type of Alopecia Areata.
