What is Alopecia Areata?
Alopecia areata is an autoimmune disorder that affects hair growth. It causes hair loss in small, round patches on the scalp, face, and other areas of the body. In some cases, it can progress to complete baldness.
Alopecia areata affects both men and women and can occur at any age. It is estimated to affect 2% of the population worldwide.
How Does Alopecia Areata Spread?
Alopecia areata is not contagious and cannot be spread from person to person through contact. However, the exact cause of the condition is unknown, and it is believed to involve a combination of genetic and environmental factors.
The immune system attacks hair follicles, which causes hair to fall out. This process is thought to be triggered by stress or other environmental factors, such as viral infections or hormonal changes.
Once hair loss occurs in one area, it can spread to other areas of the body. In some cases, hair may grow back on its own, but in others, it may not.
Symptoms of Alopecia Areata
The main symptom of alopecia areata is hair loss in small, round patches. These patches may be smooth or slightly scaly and can occur anywhere on the scalp, face, or body.
In some cases, hair loss may progress to complete baldness. In rare cases, hair loss may occur over the entire body, a condition known as alopecia universalis.
Diagnosis of Alopecia Areata
Alopecia areata is diagnosed based on a physical exam of the affected area and a review of medical history. In some cases, a scalp biopsy or blood test may be done to rule out other conditions that cause hair loss.
Treatment for Alopecia Areata
There is no cure for alopecia areata, but there are treatments available to help manage symptoms. These include:
- Corticosteroids: These are anti-inflammatory drugs that can be applied topically, injected into the scalp, or taken orally.
- Topical immunotherapy: This involves applying a chemical to the scalp that causes an allergic reaction, which can stimulate hair growth.
- Anthralin: This is a tar-like substance that can be applied to the scalp to promote hair growth.
- Minoxidil: This is a topical medication that is used to treat hair loss and can stimulate hair growth in some cases.
