Alopecia Areata is an autoimmune disease that affects more than 5 million Americans. Its cause is unknown, but people who develop alopecia areata tend to generally be in good health. This condition usually starts with patchy hair loss on the scalp but can progress to total hair loss on the scalp or even all over the body. Some scientists believe that some people are genetically predisposed to develop alopecia areata and that a trigger, such as a virus, sets off the condition. A family history of this disease makes you more likely to develop it. With alopecia areata, your hair generally grows back, but you may lose and regrow your hair a number of times.

This type of hair loss involves a change in your normal hair growth cycle. It may occur when a physical or emotional shock causes hair roots to prematurely enter the resting state. After the affected hairs fall out, the hair follicles become active again and new hair starts to grow. Telogen Effluvium may follow emotional distress, such as a death in the family or a physiological stress, such as a high fever, sudden or excessive weight loss, extreme diets, surgery, or metabolic disturbances. Hair typically grows back once the condition that caused it has been corrected, but this usually takes months.

A variety of medical treatments can interrupt the hair growth cycle and cause hair loss. Chemotherapy or radiation therapy can cause temporary hair loss, and in those situations LH Hair can be of great help in planning for, managing, and getting through the hair replacement process. Diseases including Lupus and thyroid disorders also cause temporary or permanent hair loss, as can infections of the scalp and some prescription medications.

Having inadequate protein, iron, or other nutrients in your diet can cause you to experience hair loss. Fad diets, crash diets, and certain illnesses, such as eating disorders, can lead to the types of nutrition problems that cause hair loss.
