Hair Loss and Thyroid Dysfunction

The thyroid has a surprisingly important role in the body relative to its size. This small, butterfly-shaped gland in the neck produces a hormone (aptly named thyroid hormone, or TH) that regulates your body’s temperature, metabolism, and even your heartbeat. If this little gland starts producing too much or too little TH, however, the symptoms can affect a wide variety of bodily functions.

Many early symptoms of thyroid dysfunction go untreated due to the fact they can reasonably be attributed to other factors. Feeling sluggish and gaining a little weight, for example, are easy to dismiss as a part of getting older. It is often when the illness progresses and symptoms become more prominent and affect other parts of the body that patients begin to realize there is an issue.

Thinning hair is a common symptom for people whose thyroid is producing both too much (hyperthyroidism) or too little (hypothyroidism) TH. With hypothyroidism, hair becomes dry and brittle and can easily break or fall out, giving the appearance of thinning hair. In addition to the hair loss on their head, sufferers of hypothyroidism can experience hair loss or thinning on their arms, legs, or even eyebrows, while hyperthyroid patients generally only experience issues with the hair on their heads. The changes in and ultimate loss of hair is caused by the unnatural levels of TH interrupting the growth cycle of your hair. The hair growth cycle is broken down into three phases: growth (anagen), resting (catagen), and expulsion (telogen). TH imbalances rush follicles into the resting phase, where the hair stops growing and begins its journey to the surface of your scalp where it will ultimately fall out. When this happens to too many follicles, hair becomes thin and hair loss occurs.

The good news is hair loss that is caused by thyroid problems is often treatable with the help of a medical professional. The first step is visiting your physician and talking about your symptoms. They will likely order a blood test to determine the amount of TH in your body. In addition to medication that will bring the amount of TH in your system back to an appropriate level, some patients will seek out other treatments to reduce the symptoms they experience. For patients with thinning hair, low-level light therapy with the LaserCap® may be an effective way to slow, stop, or reverse hair loss.
