Hypothyroidism and Hair Loss: Understanding the Connection

Hair loss can be caused by a variety of factors, including damaging hairstyles and fungal infections. A hormonal imbalance due to a condition like hypothyroidism can also prevent normal hair growth.

Hypothyroidism

• Hypothyroidism is a condition that usually affects women over 50. It occurs when your thyroid gland does not produce enough thyroid hormone.

Hair Growth

• Hair growth occurs in three stages: first hair grows, then the hair rests and then it is shed before the cycle begins again. A hormone imbalance can interfere with this cycle, preventing normal hair growth.

Thinning Hair

• Thinning hair is one of the symptoms of hypothyroidism. An underactive thyroid can also cause hair to fall out.

Treatment

• Hair loss due to hypothyroidism is remedied through treatment of the problem with your thyroid. This usually involves medication to replace the lacking thyroid hormone.

Considerations

• If you stop taking your medication, your hypothyroidism could return and your hair growth could stop once more.
