Can Thyroid Disease Cause Hair Loss

Why Is Thyroid Function Important To Your Hair

(TBS #15) Why Does Hypothyroidism (& Hashimotos) Cause Hair Loss?

Having either hypothyroidism or hyperthyroidism can limit your bodys production of hair cells, which can cause hair loss, hair thinning or reduced hair growth. Thyroid dysfunction can also be associated with low iron levels, which in turn can also adversely affect hair growth .

Both hypothyroidism and hyperthyroidism are easily diagnosed by low or high thyroid readings in blood test results. However, readings just within the normal range should also be looked at if you are experiencing hair loss. Please consult with both your doctor and a Philip Kingsley Trichologist if you are concerned.

Common thyroid conditions such as Hashimotos thyroiditis and Graves disease are autoimmune disorders, which can sometimes result in hair loss.

The hair loss is typically reversed after your thyroid hormone levels are normalized. But this may take some time.

Its important to point out that hair loss may not just be caused by your thyroid, however.

Having one autoimmune disorder also increases your risk for having others, some of which produce hair loss:

  • Celiac disease can be associated with iron deficiency, which triggers hair loss.
  • Alopecia areata, a skin condition, causes hair to fall out, typically leaving round spots without hair.

And for women, menopause creates a low estrogen state that can thin the hair follicles, giving the appearance of overall hair loss.

If youre shedding hair, I would definitely tell your physician, who can determine the reason. Doctors can sometimes prescribe treatments to minimize or reverse hair loss.

Complications Of Hashimotos Disease

Thyroid hormones are crucial for the normal functioning of body systems. If Hashimotoâs disease is not treated, it may result in some complications such as:

Heart problems

Hypothyroidism may lead to poor heart function. It could also result in an enlarged heart or irregular heartbeat. In severe cases, the disease could trigger high levels of bad cholesterol that substantially increase the risk for cardiovascular disease and heart failure.


Undiagnosed or untreated severe hypothyroidism can cause myxedema. The symptoms of this condition manifest through skin changes, such as swelling of the face including lips, eyelids, and tongue, and swelling and thickening of skin anywhere on the body, especially the lower legs.

Severe hypothyroidism, when left untreated, can lead to myxedema coma, a rare but life-threatening condition.

Signs of myxedema coma can include extreme fatigue, reduced consciousness, fever, or a drop in body temperature, particularly during the colder months.

If you think you or someone you know could be experiencing signs of myxedema coma, you must seek urgent medical care.


Enlargement of your thyroid gland is referred to as a goiter. When thyroid hormone production reduces because of Hashimotoâs disease, the thyroid gets signals from the pituitary gland to make more. This cycle results in a goiter that could affect your appearance and interfere with swallowing or breathing.

Thyroid conditions such as hypothyroidism and hyperthyroidism can cause a diverse range of symptoms, from reduced or increased energy levels to changes in your body composition and weight. Its also possible for these conditions to affect your hair.

Because your thyroid plays a vital role in regulating so many bodily functions, any disruption to the production of thyroid hormones such as triiodothyronine and thyroxine can affect numerous important bodily processes.

This includes the healthy growth of your hair. If your thyroid function is impaired, your hair might not grow as quickly as it normally would. This means that as old hairs reach the end of their hair growth cycle, they arent adequately replaced by new ones.

Symptoms of hypothyroidism include:

  • Vision problems or eye irritation
  • Goiter or enlarged thyroid gland
  • Irregular menstrual periods
  • Muscle weakness or uncontrollable tremors

Symptoms of hyperthyroidism include:

What Causes The Link Between Thyroid Issues And Hair Loss

The root causes for hair loss and thyroid problems are the same. In most cases, theyre caused by a lack of iodine in the diet.

Both hair loss and thyroid problems happen when theres not enough iodine in the body to meet all of our nutritional needs. That also means that fixing one will fix the other.

Treating your thyroid problem is often the best way to treat your hair loss as well, because it solves both problems at once! The thyroid controls how much hormone is produced in the body. When this hormone isnt regulated properly, it can create all kinds of health problems, like hair loss or thyroid issues.

You dont have to take any medication for these issues if you simply change your diet. Increasing your intake of iodine-rich foods can help you avoid these conditions altogether or fix them if youve already developed either problem.

There Are Root Causes Behind Thyroid Hair Loss

Thankfully, after a long journey to restore my thyroid function, my hair returned to being as full and healthy as ever. However, when I first meet with thyroid patients, they are oftentimes struggling with thyroid hair loss even while being treated for their thyroid dysfunction.

As with many health issues, this is often because conventional medicine doctors fail to identify and address the root cause of thyroid symptoms. I discuss all of these environmental root causes in my book, The Thyroid Connection.

In this article, Ill share ten tips for addressing the root causes of thyroid hair loss and getting your hair back to being full, shiny, and healthy!

How To Stop Hair Loss Due To Thyroid Issues


In order to stop the hormonal interference that is preventing hair regrowth, you need to balance your thyroid levels.

Your TSH and T4, in particular, need to be at optimal levels .

It may help to also check your iron levels and boost your intake.

Low iron levels will cause a lack in Ferritinwhich is a blood protein that supports hair growth.

Your thyroid issues may cause low Ferritin levels, which can contribute to your hair loss symptoms.

Increase your protein intake and healthy fats in your diet since these are both important factors in supporting stronger and healthier hair.

Reduce your stress levels. Stress can disrupt your hormonal balance with a cortisol overload.

Even if your thyroid levels are improving, your stress can still impact your hair growth cycles.

Feeling stressed with the balance of life, the frustration of hair loss and the fatigue of thyroid disease can cause hair loss months later, so be patient in reducing your stress levels and watching for future improvements.

What Could Be The Cause

Hair loss is a common symptom of thyroid disease but it can also be caused by various other conditions including vitamin and mineral deficiencies and certain medical conditions.

Lets look at thyroid disease first. Hair loss may be associated with hyperthyroidism and hypothyroidism1. In hypothyroidism Hypothyroidism “a term used to describe an under-active thyroid gland” , hair loss is also found in other areas of the body such as the eyebrows , under the arms and the pubic area.

We have seen reports that hair loss can be a side effect of levothyroxine.2 However, it may be that the hair loss is actually a symptom of hypothyroidism that only showed as a symptom after the start of treatment with levothyroxine Levothyroxine “a synthetic thyroid hormone commonly given to treat an under-active thyroid. It is also known as L-thyroxine” . This may be because it can take months for hair loss to start due to the long hair growth cycle.

It may also be a sign that you are on too much levothyroxine, making you a little overactive and this may therefore be causing the hair loss.

We have read reports from patients, though, that they moved over to natural desiccated thyroid and their hair loss improved.

If your hair loss is due to thyroid disease once you have been treated with the correct thyroid medication for you and your levels are stable, the hair loss should improve.

Carpel Tunnel Syndrome / Tendinitis

Carpel Tunnel Syndrome and tendinitis are both indicators of a thyroid problem.

It is not just these problems if you are suffering from aches and pains in your muscles and joints, and if your arms are becoming weaker, you could well be suffering from a thyroid problem.

When coupled with hair loss, you have another reliable indicator.

How Thyroid Hormones Cause Hair Loss

Your hair follicles follow a natural cycle of hair growth and resting phases. At any given time, most of your hair is growing while only a small portion of it is resting. But when changes in the body throw off that cycle, too much hair rests at one time and not enough grows, resulting in excessive hair loss, thinning hair, or balding.

Many medical conditions can cause hair loss, with thyroid disease a common culprit. Thyroid problems include both an underactive thyroid gland and an overactive thyroid gland . Because hair growth depends on the proper functioning of the thyroid gland, abnormal levels of thyroid hormone produced by this gland can result in hair changes, along with many other side effects, if left untreated. When there is too much thyroid hormone, the hair on your head can become fine, with thinning hair all over the scalp. When there is too little of this hormone, there can be hair loss, not just on the scalp, but also anywhere on the body.

Ironically, taking the hormone levothyroxine to treat an underactive thyroid can contribute to some hair loss, among other side effects, but this seems to be more common within the first month of treatment and more often in children than adults. This hair loss is only temporary and will go away as treatment is continued and thyroid hormone levels stabilize.

Levothyroxine & Hair Loss – 3 CAUSES HOW TO STOP IT

If you have thyroid-related hair loss, youll likely see hair regrowth after treating the underlying thyroid disease. In some cases, though, your hair loss could also be from one of the other causes of hair loss.

Here are some common ways to treat hair loss from other causes:

  • Minoxidil is a topical solution applied directly to the scalp, which may help stimulate hair growth.
  • Finasteride is an oral prescription medication to treat male pattern baldness.
  • Nutrition supplementsIf your hair loss is caused by a nutrient deficiency, like a lack of biotin, taking a supplement may resolve the hair loss. Speak with your healthcare provider about getting tested before starting a supplement regimen since only a small subset of people dont get enough of their daily vitamins from the food they eat.

Off-kilter hormones can easily disrupt the delicate hair growth cycle. This disruption is especially true for thyroid hormones, which are responsible for regulating the cellular growth and metabolism of every cell in your body. Hair loss is a common side effect of hypothyroidism, but it is a treatable problem. However, many people wonder if levothyroxine, the most commonly prescribed treatment option for hypothyroidism also causes hair loss. Ahead, a look at if levothyroxine causes hair loss.

Thyroid Function And Hair Loss

A Brief ExplanationThyroid hormone accurately controls cellular metabolism and effects virtually every cell in the body, powerfully impacting multiple organ systems and precisely regulating metabolism and our Basal Metabolic Rate or BMR. BMR is the amount of energy, or calories, all of the cells in our body require, at rest, to support normal cellular function. Thyroid abnormalities can therefore cause, or make worse, a multitude of health problems.

Hair follicles are especially vulnerable. The rapidly replicating cells, located in each hair follicle require an extraordinary amount of energy, nutrients and ideal condidtions to function effectively. A minor change or disruption of these requirements can have profoundly detrimental effects on the delicate milieu required for normal healthy hair growth.

The hair follicle is therefore a sort of barometer of our overall health and well-being and, as such, our hair is especially vulnerable to the numerous metabolic, physiologic, and hormonal changes caused by thyroid disease.

Having optimal thyroid function is therefore essential for healthy hair growth. Sub-optimal thyroid function can cause hair shedding, hair loss, brittleness, frailness, as well as adverse changes in the overall morphology and appearance of the affected hair strands.

Thyroid Hormone ProductionThe thyroid produces two types of hormone, thyroxine and triiodothyronine . T4 is first produced and then converted to T3, the more active form of thyroid hormone.

Thyroid Conditions And Alopecia Areata

Many people with thyroid conditions such as hypothyroidism and hyperthyroidism suffer from autoimmune thyroid disease. People affected by autoimmune thyroid disease have a greater risk of developing other autoimmune conditions, such as alopecia areata.Alopecia areata is a type of autoimmune hair loss in which the bodys immune system targets and damages the hair follicles. Hair follicles that are targeted by the immune system can stop producing new hairs, resulting in hair loss.

Hair loss from alopecia areata usually occurs in small, often circular patches, rather than the receding hairline or crown hair loss of male pattern baldness or the diffuse thinning of thyroid hair loss. Some people with alopecia areata develop bands of bald skin, called ophiasis.

In severe cases, alopecia areata can also cause total hair loss on the scalp, as well as loss of hair in the eyebrows, eyelashes and beard area. Some people with alopecia areata may notice that their nails become slightly red, with a weak, rough and brittle texture or may have pitting in their nails.

If you have a thyroid condition and believe youre suffering from alopecia areata, contact your healthcare provider.. Several effective treatments can help you to manage the symptoms of alopecia areata, including corticosteroids.

Medications that stimulate hair growth, such as minoxidil, may also help to promote hair growth in people with alopecia areata.
