Quizplus · Accepted Answer

In most cases, baldness is a result of the aging process or heredity. It can, however, be a consequence of certain systemic illnesses, such as thyroid diseases, iron deficiency anemia, syphilis, or an autoimmune disease. Certain forms of dermatitis (see "dermatitis" section) can also cause alopecia. Chemotherapy and radiation therapy are used to treat cancer, and some other types of medications may lead to thinning and loss of hair. The hair often grows back after treatment has been completed. More often, however, hair loss is not attributed to any specific disease process.
