Hi Prakash garu, Alopecia areata is thought to be an autoimmune disease. The immune system makes white blood cells and antibodies to protect against foreign objects such as bacteria, viruses, and other germs. In autoimmune disease, the immune system mistakes part or parts of the body as foreign. In people with alopecia areata, many white blood cells gather around the affected hair roots (hair follicles) which are mistaken as foreign. This causes some mild inflammation which leads in some way to hairs becoming weak and falling out to cause the bald patches. The possible triggers include: viruses, infection, long use of antibiotics or other environmental factors. Patchy hair loss: The problem often begins with 1 or more coin-sized, round, smooth, bare patches where hair once was. You may first notice the problem when you see clumps of hair on your pillow or in the shower. Homeopathy addresses the underlying autoimmune disease process while treating Alopecia Areata so the results are long lasting and of course, the treatment is free from any adverse effects.
