One of the more psychologically unpleasant and frustrating side effects that can occur with either hyperthyroidism or hypothyroidism is hair loss. There is no way to predict which patients will experience hair loss and which will not. Similarly, there is no way to predict who will be severely affected and who will have only minimal hair loss.

Because each person is unique, responses to thyroid disease and treatment will vary. This can be disturbing to patients who have lost a great deal of hair and want to know exactly when this will stop and when their hair will be normal again.

Here are a few facts to remember if you experience hair loss because of hyperthyroidism or hypothyroidism:

• Hair loss from thyroid disease is usually reversible with proper treatment of the thyroid condition.
• Typically hair loss does not immediately stop when the blood work becomes normal. Most people stop losing their hair and begin replacing lost hair a few months after the thyroid hormone levels become normal. In some cases, it can take longer.
• Stress can contribute to hair loss. Because of the nature of thyroid disease, it can have a direct impact on the psychological well-being of patients, particularly on the coping mechanisms that deal with stress. Unfortunately, as patients become more and more concerned about their hair loss, their stress levels increase, making the situation worse.
• It is advisable to take caution when considering chemical treatments of the hair-for example, coloring or permanent waves. If at all possible, avoid such treatments until the hair loss has stopped.
• Cutting the hair shorter, using moisturizing and conditioning hair products, and avoiding back combing are other methods to decrease stress on the hair.

The most important things you can do to minimize further hair loss are to faithfully take prescribed thyroid medications and to be calm and patient.

Most patients with hypothyroidism have some degree of associated depression, ranging from mild to severe. 10% – 15% of the patients with a diagnosis of depression may have thyroid hormone deficiency. Patients with depression should be tested to determine if they have a thyroid disorder.

• Several research studies have been done and continue to be done on the association between depression and thyroid disease. Although all forms of depression, including bipolar disorders like manic depression, can be found in either hypothyroidism or hyperthyroidism, depression is more often associated with hypothyroidism. Many patients with hypothyroidism have some degree of associated depression, ranging from mild to severe.
• If a large population of depressed patients was screened, a significant percentage, perhaps 10% – 15%, would be found to have thyroid hormone deficiency. For this reason, patients with a diagnosis of depression should be tested to determine if they have too little thyroid hormone. If they do, thyroid medication should be prescribed.
• Thyroid hormone is sometimes prescribed for depressed patients with normal thyroid function because it magnifies the beneficial effects of certain antidepressants.
• Lithium, a commonly prescribed drug for certain types of depression, has profound effects on the size and function of the thyroid gland. Patients taking lithium need periodic examinations of their thyroid gland and thyroid function.
