What is Alopecia Areata?


Alopecia Areata is a condition causing hair to fall around in different small patches, which generally goes unnoticed. This disease generally develops when the human immune system attacks the hair follicles, thereby resulting in hair loss. A person suffering from this disease might be facing sudden hair loss in the scalp and even in the eyelashes, eyebrows, and face. In most cases, it develops slowly and recur after years between all the instances. Alopecia Areata might also result in a total hair loss, which is also called Alopecia Universalis, and it can also prevent hair from growing back. The overall extent of hair regrowth and hair loss varies from one person to another. As of now, there isn’t any cure for this condition. However, there are a few treatments that might help in overall hair growth and can further prevent future hair loss. Several resources are available in order to help people to cope up better with all the stress related to hair loss.

Key Causes Of Alopecia Areata

Alopecia Areata is an autoimmune condition that is mainly developed when the body’s immune systems mistake healthy cells for foreign substances. In most cases, the immune system defends a human body against different types of foreign invaders such as bacteria and viruses. In case you are suffering from alopecia areata, your immune system might start attacking all your hair follicles. These hair follicles are the structures from which the hair starts growing. This disease further causes the hair follicles to become smaller thereby stopping the production of hair while leading to hair loss.

In most cases, this disease usually happens in people who have a family history of other autoimmune disorders such as rheumatoid arthritis, type one diabetes, etc. This is the main reason why some scientists suspect that genetics might contribute to the overall development of alopecia areata. It is also believed that several factors in the environment also triggers alopecia aerate especially in peoples who are genetically predisposed to the disease.
