Thyroid Problems and Hair Loss: What's the Connection?

The thyroid gland is a small butterfly-shaped gland in the neck that plays a vital role in metabolism. When the thyroid gland is not functioning properly, it can cause a range of health problems, including hair loss.

Thyroid Problems and Hair Loss

Hair loss is a common symptom of thyroid problems, especially hypothyroidism (an underactive thyroid gland) and hyperthyroidism (an overactive thyroid gland). In fact, hair loss is often one of the first signs of a thyroid problem.

Symptoms of Thyroid Problems

Other symptoms of thyroid problems include fatigue, weight gain or loss, mood changes, and changes in body temperature.

Causes of Hair Loss in Thyroid Problems

Hair loss in thyroid problems is caused by changes in the hair growth cycle. Normally, the hair growth cycle is divided into three phases: the anagen phase (growth phase), the catagen phase (transition phase), and the telogen phase (resting phase). In people with thyroid problems, the hair growth cycle is disrupted, resulting in hair loss.

Treating Thyroid Problems and Hair Loss

The good news is that hair loss due to thyroid problems can be treated. The first step is to get the thyroid problem under control with medication. Once the thyroid is functioning properly, hair growth will usually return to normal within six to twelve months.

Managing Hair Loss Due to Thyroid Problems

In the meantime, there are things you can do to manage hair loss due to thyroid problems. Maintaining a healthy diet, getting enough sleep, and reducing stress can all help promote hair growth. Additionally, using hair care products that are gentle on the scalp and avoiding harsh treatments like coloring or perming can also help prevent further hair loss.
