May be low thyroid: Your best option now is to have a thorough evaluation from your family doctor as well as a Psychiatric consultation. Your depression and hair loss could be caused by stress, low thyroid, medications, or clinical depression. By seeing two qualified physicians who can accurately determine a correct diagnosis, you have the best chance of receiving proper treatment.
