Alopecia Areata and Patchy Hair Loss

Alopecia Areata and Patchy Hair Loss

Alopecia areata is a condition characterized by the sudden occurrence of hair loss in circular or oval patches on the scalp or other areas of the body. This hair loss is caused by the immune system mistakenly attacking the hair follicles, resulting in their destruction and subsequent hair loss.

Causes for Alopecia Areata

Although the precise cause of alopecia areata remains unknown, it is believed to be influenced by a combination of genetic, environmental, and immune system factors. It is considered an autoimmune disorder, wherein the immune system incorrectly identifies the hair follicles as foreign entities and targets them for attack. Other factors like hormonal imbalances, certain viral or bacterial infections, and stress may contribute to the onset or exacerbation of the condition.

How do we Treat Alopecia Areata?

The treatment objective for alopecia areata is to stimulate hair regrowth and manage the underlying immune response. Several standard treatment options are available, including:

  1. Corticosteroids: Topical corticosteroids or corticosteroid injections into the affected areas can help suppress the immune response and promote hair regrowth.
  2. Topical Immunotherapy: This treatment involves the application of substances to the scalp that elicit an allergic reaction, which can stimulate hair regrowth. The aim is to modify the immune response and restore normal hair growth.
  3. Min-oxi-dil: While typically used for androgenetic alopecia, topical minoxidil may also be employed to encourage hair regrowth in cases of alopecia areata.
  4. Immunomodulatory Drugs: Medications that suppress the immune system, such as corticosteroids, meth-otr-ex-ate, or cyc-los-por-ine, may be prescribed for severe or widespread instances of alopecia areata.
