We wish we could say no to this one, but unfortunately hyperthyroidism is known to cause the thinning of hair and hair loss. Several abnormalities in hormones can result in hair loss including thyroid disease which is why it’s important to speak to your doctor and get a proper diagnosis to remedy your hair loss problem.

The main problem with hyperthyroidism is that it all boils down to hormones. When your hormones change as a result of thyroid disease, your whole body undergoes some physical changes.  However hair loss isn’t a permanent problem as long as you get the proper treatment.

What is the thyroid gland?

The thyroid is a butterfly shaped gland organ located at the base of your neck. The thyroid’s main task is producing and releasing hormones into the bloodstream. The thyroid fulfils a number of important functions through the release of these hormones, including the regular function of the metabolism and nervous system.

How can thyroid hormones cause hair loss?

If the thyroid gland stumbles into a minor hiccup with its functioning, it can cause a range of effects across the body, hair loss being one of those effects. When your metabolic system is unable to metabolise food into energy, this can impact your hair follicles and cause the follicles to either shut down or slow down the production of hair growth.

Thyroid disorders are split up into various thyroid conditions that may cause hair loss. These include, Hypothyroidism, Hyperthyroidism, Thyroiditis, Post-partum Thyroiditis and Myxoedema.

  • In Hypothyroidism the thyroid gland produces less thyroid hormones due to an underactive gland. If you notice a loss of hair on your scalp or some unfortunate eyebrow thinning, this could be an indicator of hypothyroidism. (However as advised, consult your doctor for a certified diagnosis.)
  • In Hyperthyroidism, the thyroid gland basically has a rager and produces more hormones than it should. In the case of hyperthyroidism, skin can become fragile and rapid hair loss is common.
  • Thyroiditis is caused by the inflammation of the thyroid gland due to a viral or bacterial infection. The inflammation of the gland could interfere with its usual functioning and lead to hair loss.
  • One in ten women are said to suffer from post-partum thyroiditis shortly after giving birth. During pregnancy and after childbirth, the body undergoes various changes that may cause metabolic changes.
  • Myxoedema is a term used with severe and hypothyroidism, however it can result from both hypothyroidism and hyperthyroidism. Myxoedema is a serious condition as the effects can be a lot more serious and potentially lead to kidney failure.

Figuring out the exact cause of a thyroid disorder is a tricky situation, but the usual culprits could include the excess consumption or lack of iodine in the diet, some prescription drugs, medical treatments, radiation poisoning and auto immune diseases.



While hair loss is a common symptom of thyroid disorders, this doesn’t mean hair loss is a direct result of thyroid disorder, as there are several other reasons for hair loss. If you experience a pain in your neck or notice any swelling, weight changes, mood changes, bowel problems or fatigue a thyroid disorder might be involved. As well as hair loss, thyroid disorders can also cause hair to dry out and become brittle.

The super good news is that, hair loss due to thyroid disease can eventually grow back overtime when the condition is under control. It is important to note however that hair loss could be part of a wider problem which is why we can’t stress it enough that you should talk to your GP asap for a diagnosis.

If you are experiencing hair loss due to the thyroid, it may only be temporary but can take time for new hair growth. You should be advised that sometimes new hair growth might differ in texture and colour when growing back.

We understand hair loss and a change to how your hair looks may be frustrating and cause a psychological impact. There are many alternatives that may help you feel better by covering up or disguising hair loss such as wigs and hair pieces.

Since hair may be sensitive and brittle due to thyroid disorders, be gentle and patient with your hair. Be wary of the products you use on your hair and try to use salon recommended brands or products that won’t dry your hair out. Be cautious when taking hair supplements as some may contain ingredients that might interfere with your prescribed medication. Avoid products that contain high levels of iodine as they can also interfere with medication or cause underactivity/over activity of the thyroid. Take supplements recommended by your GP and speak to your GP on how to maintain a healthy diet that could potentially help improve hair growth.
