Alopecia areata

In most people suffering from alopecia areata, hair is lost in certain patches, only to grow again 1 - 2 years later. Such patches can be anywhere on the scalp and multiple, with a diameter of 2.5 - 5 cm. Hair can regrow in one patch, while again falling out in another patch. Alopecia areata totalis results in the scalp losing all its hair. However only a small percentage of all hair loss patients suffer from this form of baldness. In most cases, hair loss is restricted to the head. There is however one form of hair loss - Alopecia areata universalis - where all body hair (including eyebrows, beard and pubic hair) is lost. Alopecia areata is probably an auto-immune disease where the body itself attacks the hair in a destructive and sometimes irreversible manner, as if seeing hair as something alien to the body. In many cases alopecia areata is an incurable and irreversible process. This is especially the case when alopecia areata occurs when the person is still a child or when the patient suffers from other auto-immune disorders such as thyroid disease, vitiligo or allergies.
