5. Hair & Skin Changes
The hair and skin often show the first signs of thyroid problems, including symptoms such as dry hair, loss of hair, scaly skin, or excessively dry skin. Normal, regulated hair growth is actually dependent on the proper functioning of the thyroid gland, and problems with thyroid function can cause balding of the head in both men and women, as well as the loss of body hair.
The thyroid also regulates delivery of hormones which play important roles in the maintenance of healthy skin. When the thyroid is underactive or overactive, these hormones aren’t delivered in the proper quantities, and noticeable changes in the skin are the end result.
