What is Alopecia Areata(hair loss)?
Alopecia areata(hair loss) is an autoimmune disorder that causes hair loss on the head and other sections of the body. In people with alopecia areata, the immune system mistakenly attacks the hair follicles, leading to hair loss. Alopecia areata can affect people of all ages, but it most commonly occurs in people under the age of 30.
It can cause hair loss in patches on the scalp, or it can lead to complete baldness (Alopecia totalis). In some rare cases, it can cause the loss of all body hair (Alopecia Universalis). Alopecia areata is not contagious and it is not caused by poor hygiene or a lack of proper hair care.
The exact cause of alopecia areata is not known, but it is thought to be related to genetics and environmental factors. There is no cure for alopecia areata, but treatments such as topical or injected corticosteroids, minoxidil, and immune-suppressing medications can help to slow or stop hair loss.
