Alopecia areata is a disease that causes hair to fall out in small patches. It rarely causes total hair loss, however it can prevent hair from growing back. The condition is not life threatening, does not cause pain or illness, and hair loss can stop just as suddenly as it started. It may even grow back on its own without any medical intervention. Hair loss and regrowth varies from person to person.
Alopecia Areata is an autoimmune condition in which the immune system attacks the hair follicles.
In addition, Alopecia Areata occurs more often among people who have family members with autoimmune disorders such as diabetes, lupus, or thyroid disease. Some scientists believe that genetics may be a factor, however the cause is unknown.
The main symptom of Alopecia Areata is loss of hair in small, round patches (roughly the size of a quarter) on the scalp . The disease often comes and goes in cycles, with regrowth in between.
However, other types of diseases can cause hair to fall out in this same pattern. This symptom alone should not be used to diagnose Alopecia areata
There is no way to prevent Alopecia Areata. If you are concerned about developing this condition at some point, you can find out if your relatives have it so you have an idea of whether you are susceptible to this disease.
