How Thyroid Health Affects Hair Growth

How Your Thyroid Affects Thinning Hair And Hair Loss

If you are experiencing thinning hair or hair loss, you probably didn’t know that the thyroid is at play. The thyroid is part of the endocrine system, found in the lower neck below the Adam’s apple. It plays a crucial role in several important processes in the human body including the reproduction of cells and the regulation of energy levels. Each part of the body relies on healthy thyroid hormones for optimum functioning, and this includes the hair follicles.

The hair on your head and body can provide important clues to an imbalance in thyroid levels. Hyperthyroidism, or an overactive thyroid, leads to thin throughout the head resulting in a uniformly sparse look. Hypothyroidism, or an underactive thyroid, conversely leads to hair loss on the head as well as throughout the body. Other symptoms associated with thyroid disease includes an itchy scalp, dry and brittle hair, fatigue, weight gain or weight loss, sleeplessness, and others.

Hormonal Changes

Hormone-induced hair loss occurs when an enzyme converts testosterone to DHT(dihydrotestosterone), which is a less useful version. DHT begins to attack the hair follicles causing a shrinkage and eventually making the follicles disappear completely. Hair becomes finer, thinner, and may even stop growing. In individuals with hyperthyroidism or hypothyroidism, testosterone converts to DHT at a much quicker rate.

Additionally, a 2008 study published in the Journal of Clinical Endocrinology and Metabolism revealed that human hair follicles are directly targeted by thyroid hormones. The research discusses how the thyroid hormones triiodothyrine (T3) and thyroxine (T4) regulate functions of hair biology, including hair growth.

Since hair growth is dependent on the health of the thyroid gland, any irregularities in the thyroid hormone levels will directly affect the hair, evident in changes such as thinning and hair loss. In some cases, hair loss may not be that obvious although for others, it may be extreme.

Thyroid medications can help restore the balance in thyroid hormone levels, although many report that hair loss is often experienced within the first month of taking medicine. Once hormone levels stabilize, hair growth eventually goes back to normal.

Nutrient Deficiencies

People with hypothyroidism tend to have nutrient deficiencies. Certain nutrients are needed for healthy thyroid function and also contribute to hair growth. Low ferritin in the form of iron stored in the body is a common nutrient deficiency among women who suffer from hair loss or people who have hypothyroidism in general. If you have an extreme case of hair loss or thinning, you may want to have a doctor test your iron and ferritin levels.
