Hair loss
Thyroid hormones play significant roles in the growth of hair follicles. When the hormones are low in the body, your hair follicles will stop growing. This may eventually lead to hair loss. People with insufficient levels of iodine may also suffer from hair loss.
A study of 700 people discovered that about 30% of people with low thyroid hormone levels experience hair loss. Other studies show that low thyroid hormone levels only cause hair loss in people with a family history of hair loss. If your hair loss is caused by iodine deficiency, you can add more iodine to your diet to elevate your thyroid hormone levels to treat hair loss.
