How Thyroid Disease May Cause Hair Loss
Hair health, fullness, and sheen are often indicators of the body’s internal wellness. Many diseases, conditions, and subsequent treatments trigger hair loss or dull, breaking strands. Two of those conditions are hypothyroidism, and hyperthyroidism. While they are complete opposite in terms of their issues – one is an overproduction while the other is an underproduction of hormones – they share a common symptom: hair loss.
If you suffer from a thyroid disorder and are currently experiencing hair loss or balding, knowing why and the steps you can take to combat this unfortunate side effect is important.
What is the thyroid?
The thyroid is a gland that releases a steady amount of hormones in the body. It’s pertinent to proper metabolic functions, growth, and development. The thyroid is located just below your voice box on the front of your neck. It is shaped somewhat like a butterfly with two lobes on each side connected in the center by a thin tissue. The thyroid stores hormones in small droplets within it’s vesicles, or follicles.
What does it do?
The thyroid is responsible for the production of three key hormones: T3 (also known as triiodothyronine), T4 (also known as Tetreaiodothyronine), and Calcitonin. T3 and T4 are both made up mainly of iodine.
Being the main component of two thyroid hormones, the thyroid requires iodine to function properly. Usually, the body absorbs iodine through the intestine and enters the blood stream. Then, it’s transferred to the thyroid gland to build T3 and T4. The body cannot produce iodine on it’s own since it’s a trace element.
One reason for an underactive thyroid, or hypothyroidism, is a lack of iodine. Other potential causes are genetics, age, Hasimoto’s thyroiditis, and various medications. Under-activity usually develops over time, rendering it hard to notice. The symptoms are weight gain, slowed metabolism, loss of energy, tiredness, difficulty concentrating, slow pulse, constipation, and hair loss. Many patients with an underactive thyroid assume their symptoms are part of the aging process, rather than a serious hormonal condition.
Hyperthyroidism, on the other hand, occurs from an overproduction of hormones in the thyroid gland. Energy metabolism speeds up and overactive thyroids lead to hot flashes, trembling, insomnia, racing heart, fatigue, diarrhea, weight loss, and hair loss.
Autoimmune diseases, issues with the thyroid axis, or autonomy from the pituitary gland are the three main causes of an overactive thyroid. The pituitary gland is responsible for regulating the amount of thyroid hormone produced, and a lack of communication between the two can cause overproduction.
Why does a dysfunctional thyroid lead to hair loss?
Both hypothyroidism and hyperthyroidism can cause hair loss. First, overactive thyroids sometimes lead to an increased development of DHT. DHT influences the development of sexual organs and secondary sexual characteristics, including physical appearance. But too much DHT can cause hair follicle shrinkage or elimination, resulting in shedding or thinning hair. Therefore, when an overactive thyroid impairs the production of DHT from testosterone, balding occurs.
For patients currently prescribed medication for an underactive thyroid, it’s important to note the side effects. One of the most common treatments is levothyroxine sodium, which also goes by the brand names Synthroid, Levoxyl, Levothroid, and Unithroid. Sythroid specifically has been shown to cause long-term hair loss in patients.
How to treat thyroid-related hair loss
Whether you’re suffering from hair loss due to a hormonal imbalance from hypothyroidism or your thyroid medication is causing your hair loss, you have options for treatment.
First, many individuals take additional medication to offset the hair loss from their current thyroid medication. Results vary since medication affects every individual differently, but make sure to consult your physician prior to adding or subtracting from your current regimen.
Hair transplant surgery is another treatment option known to deliver consistent results. Given the advances in hair transplants, such as the Follicular Isolation Technique (FIT) developed by Dr. Paul Rose, transplants are more naturally looking than ever. Using FIT, Dr. Rose extracts individual follicles from donor areas and moves them to balding areas with little scarring. Follicular Unit Transplantations (FUT) is a more traditional approach offered by many restoration experts, including the Hair Transplant Institute of Miami.
Many individuals aren’t candidates for additional medication or hair transplant surgery after suffering from thyroid-related hair loss. Low-level laser therapy, or LLLT, uses safe lasers to stimulate hair follicles. At-home laser caps can be worn underneath virtually any hat or covering.
