What is Alopecia Areata ?
Alopecia areata is thought to be an autoimmune disease. This occurs when your own immune system damages healthy cells in your own body. The immune system makes white blood cells (lymphocytes) and antibodies to protect against foreign objects such as bacteria, viruses, and other germs. It is not known why it is common for only certain areas of the scalp to be affected. Also, the affected hair follicles are not destroyed. Affected hair follicles are capable of making normal hair again if the immune reaction goes and the situation returns to normal.
The most common form of alopecia areata treatment is the use of corticosteroids, powerful anti-inflammatory drugs that can suppress the immune system. These can be administered through local injections (most common), topical ointment application, or orally. Scalp microblading/ micro pigmentation is another alternative , to camouflage the patches.
