Does Thyroid Cause Hair Loss?

Yes, thyroid disorders can cause hair loss. The thyroid gland produces hormones that regulate the body’s metabolism. When the thyroid gland is not functioning properly, it can lead to imbalances in hormone levels, which may contribute to hair loss.

There are two main thyroid disorders that can impact hair health:

  • Hypothyroidism: In hypothyroidism, the thyroid gland does not produce enough thyroid hormones, resulting in a slowdown of bodily functions. Hair loss is a common symptom of hypothyroidism. The hair may become thin, brittle, and may fall out more easily. Hair loss related to hypothyroidism typically occurs on the scalp but can also affect other body hair.
  • Hyperthyroidism: In hyperthyroidism, the thyroid gland produces an excessive amount of thyroid hormones, leading to an acceleration of bodily functions. Hair loss can also occur in hyperthyroidism, though it may present differently than in hypothyroidism. With hyperthyroidism, hair loss might be diffuse or patchy, and the hair can become finer.

It’s important to note that hair loss related to thyroid disorders is usually reversible with appropriate treatment for the underlying thyroid condition. If you suspect that your hair loss is linked to a thyroid problem, it is advisable to see a healthcare professional, who may conduct blood tests to assess your thyroid function and recommend appropriate treatment or medication if necessary. Treating the thyroid disorder can often help improve hair loss and promote hair regrowth.
