Considering your age, some of the common causes for your hair fall are: age related, nutritional deficiency, drop in levels of female hormone after menopause, chronic illness and side effect of any ongoing medication. Make sure you consume a well balanced and nutritious diet. Avoid using harsh chemical and shampoo. Massage your hair with warm oil once a week. Do not comb hair when they are wet. If you are on any medication talk to your doctor about its possible side effects.
