Thyroid problems can cause dry hair in some people. Dry hair can be a symptom of hypothyroidism, a condition in which the thyroid gland makes too little thyroid hormone. In addition to dry hair, symptoms of hypothyroidism also include dry, brittle nails, fatigue and weakness, heavy menstrual periods, sensitivity to cold, and joint pain. If you have any of these symptoms as well as dry skin, consult your doctor.
