Underactive Thyroid in Men (Hypothyroidism)

Hypothyroidism occurs when the thyroid gland doesn't create enough hormones. There's no way to prevent low thyroid in males unfortunately, as most cases are caused when the immune system attacks the thyroid gland damaging it. It's easily treated with a daily hormone tablet which replaces the hormones your thyroid gland isn't making.

Does hypothyroidism cause hair loss? It's important to know that hair loss is a side affect in severe and prolonged circumstances. It's very rare for those who have a mild condition. However, when hair is lost, hypothyroid hair loss pattern is all over the scalp rather than in patches, and usually grows back once the thyroid disorder is treated, although this may take a while.

Overactive Thyroid in Males (Hyperthyroidism)

The exact opposite of hypothyroidism, hyperthyroidism occurs when the thyroid gland produces too much hormones. Extra levels of this hormone can cause unpleasant and serious problems that could in turn need their own treatment.

There are a few ways you can develop hyperthyroidism, the main three being Grave's disease, where the body mistakingly attacks the thyroid gland, lumps (nodules) on the gland and finally it can be caused by certain medication, such as heart medication.


It can be treated with daily medication, the removal of the some or all of the thyroid gland or radioiodine treatment, which damaged the gland in order to stop it from over producing the hormones.

Just like hypothyroidism, hyperthyroidism hair loss is incredibly rare and found in severe circumstances. Hair loss can be caused by the medication very rarely, however it's difficult to tell whether it was caused by the condition or the medication.

Symptoms of Overactive Thyroid Problems in Men

There are several signs of this thyroid problem in males such as anxiety and irritability, mood swings, difficulty sleeping, tiredness, sensitivity to heat, swelling in your neck from the thyroid gland, irregular or fast heart rate and weight loss.

Unfortunately having one autoimmune disease means you're more likely to get another, which means if someone has Graves’ Disease or Hashimoto’s Thyroiditis (hypothyroidism), they're more likely to have alopecia areata. So the problems don't just end at male thyroid problems. Hashimoto's hair loss, thyroid hair thinning and thyroid hair loss pattern is only an affect if the thyroid is left untreated.

On That Note

Does thyroid problems cause hair loss? Unfortunately the answer is yes, but only in severe and prolonged cases. Thyroid is often found in those with alopecia areata due to them both being autoimmune diseases, however the hair loss can be treated. Once the thyroid is treated, the most hair will usually grow back, although this can take a little while. If you are worried about this or your current rate of hair loss then it is best to speak to a professional who can advise you on hair restoration options.
