Alopecia-areata

The Alopecia areata is a type of non-scarring alopecia that is characterized by bald spots on the scalp. Multi-factorial origin, most investigations consider it an autoimmune disease. The patient’s immune system attacks the hair follicles, causing an interruption of the normal hair development cycle.

It is a chronic disease that does not heal. It can be controlled and do not have a visible impact on the patient; if the appropriate treatment is taken, in most cases the hair will recover in a few months, but the patient will always be at risk of developing the disease.

In the cases of very severe alopecia areata or in those casese in which the it is not the proper treatment is not taken, it can turn to an irreversible loss of hair.
