Alopecia Areata (AA)
What is Alopecia Areata (AA)?
Alopecia Areata (AA) is an autoimmune disorder that causes small bald patches on the scalp. It occurs when the body’s immune system mistakenly attacks the hair follicles, resulting in hair loss on the scalp, face, and sometimes other parts of the body. While the exact cause of AA is unknown, genetic and environmental factors may play a role in triggering it.
What are the Symptoms of Alopecia Areata?
The most common symptom of AA is the sudden development of one or more small bald patches that appear either on the scalp or other areas of the body. Other signs and symptoms of AA include:
- Itchy scalp
- Rapidly spreading bald patches on the scalp, eyebrows, or beard
- Fingernails that are pitted, ridged, or brittle
Diagnosis and Treatment of Alopecia Areata
A doctor can diagnose AA by examining the scalp and reviewing your medical history. Other tests such as a blood test may be required to rule out other medical conditions. Treatment for AA may include medication, corticosteroid injections, light therapy, or surgery (in severe cases).
Living with Alopecia Areata
Living with AA can be challenging, but there are steps you can take to cope with the condition. These include:
- Wearing a wig to cover bald patches
- Getting psychological counseling to help deal with the stress of the condition
- Using natural remedies such as massage or topical creams
- Making lifestyle changes such as avoiding hair styling products or tight headwear
