In a majority of cases of Alopecia Areata, the hair falls out in small patches about the size of a quarter, while in some people, the condition might be extreme. Sometimes, the Alopecia Areata leads to a complete loss of hair on the scalp (Alopecia Totalis), and sometimes the hair loss is present in the entire body (Alopecia Universalis).

Why Does Alopecia Areata Occur?

Being an autoimmune disorder, alopecia areata develops when the immune system of the body mistakes its own healthy cells for foreign body and attacks the hair follicles. Hair follicles are the structures from which hair growth occurs. When attacked, these follicles become small and stop producing hair, leading to hair loss. The exact cause as to what triggers the immune system in behaving in this manner in alopecia areata is not yet known.

People who have a family history of any autoimmune disease, such as rheumatoid arthritis or type1 diabetes are more at risk for developing alopecia areata.

Is Alopecia Areata Permanent?

Alopecia areata is not a permanent condition for everyone. The hair may or may not grow back. Sometimes the treatment options also prove to be helpful in bringing back the lost hair. There is no cure for alopecia areata, though treatments are available to slow down the hair loss or to help hair grow back quickly. For most of the patients, the condition resolves without any treatment, while in some it might be permanent loss of hair.

Various steroid creams, lotions, and shampoo are prescribed as treatment of alopecia areata. Oral corticosteroids are known to induce hair growth in the affected people, but their long term use is contraindicated due to undesirable side effects.

Immunotherapy works on producing an allergic reaction in the body to grow hair back.

Various alternative therapies and home remedies propose treatment of alopecia. Though not supported by any research, these remedies prove to be beneficial and give no side effects when treating alopecia areata.

The effectiveness of the treatment also varies in different individuals.

How Serious is Alopecia Areata?

It is difficult to predict the extent of Alopecia Areata.

If the hair loss involves the hair of the temporal and occipital region, or if there are larger areas of scalp involved for a long period of time, the prognosis is worse for patients with Alopecia Areata.
