Can Low Thyroid Cause Hair Loss

Surgery For Thyroid Disorders

Hashimoto’s and Hair Loss

Removing the thyroid gland can cure hyperthyroidism, but the procedure is only recommended if antithyroid drugs don’t work, or if there is a large goiter. Surgery may also be recommended for patients with thyroid nodules. Once the thyroid is removed, most patients require daily supplements of thyroid hormones to avoid developing hypothyroidism.

Treatment Options For Thyroid Hair Loss

Treating thyroid-related hair loss requires treating the thyroid problem. A doctor will usually prescribe a synthetic hormone containing levothyroxine to treat an underactive thyroid. Treatment for an overactive thyroid varies from person to person. Some of the most common methods include: antithyroid drugs, iodine intake, surgery. In this article we cover how to tackle the symptom of thyroid problems however bear in mind that the root cause needs to be treated as a priority, since the symptoms can only be alleviated to a limited extent. The best approach would be to get your blood tested and understand what is the optimal level of T3 / T4 hormones your hair will return to normal as a result of the treatment and over a course of time.

Meanwhile, home remedies and lifestyle changes available for sufferers of both conditions. Those can take a few weeks or months to work so it is important to approach it with a curious mind and willingness to learn about what works for your body, as opposed to expecting overnight results.

As a general rule, eating a balanced diet can help to promote growth and improve the condition of hair. A healthful and balanced diet is one that contains protein, fruits, vegetables, grains, and a moderate amount of fat.

How To Slow Or Reverse Hair Loss

The best way to restore your hair is to treat underlying conditions like hypothyroidism. Although it can be hard to wait, be patient with your body as it learns to adjust to your thyroid medication.

Aside from medication, there are several other steps you can take to boost hair thickness and growth.

Eat a well-balanced diet

Hair requires plenty of nutrients that are abundant in wholesome foods like vegetables, fruits, and meat. To increase the rate your hair grows and for more density, eat foods with plenty of iron, keratin, zinc, and vitamins A, B, C, D, and E.

If you try a supplement to boost your nutrient intake, you may wish to look for one with biotin. Bear in mind that biotin can interfere with some thyroid lab results, so check with your lab to ask if you should avoid taking biotin before testing your thyroid.

Note: Paloma Health’s lab uses a specialized assay, so there is no need to delay your medications or supplements, including biotin. You may also take the Paloma Health at-home thyroid test with or without regard to food, so no need to fast.

Limit harsh styling practices

Coloring, permanents, and hot styling tools are some of the most harmful things you can do for your hair. However, many of us use these practices to get the look we want. If you style your hair with anything that may cause damage, try to limit it as much as possible.

And Finally Your Thyroid Levels

If the thyroid system is unbalanced and becomes either low or high it can affect your hair. Although thyroid medications are also described as being associated with hair, it is the underlying thyroid condition that is associated with hair loss not its correction.

Specifically in hypothyroidism the bodys ability to regenerate cells is slowed and a characteristic symptom of having lost your hair due to this thyroid condition is the loss of hair on the outer edge of your eyebrows. This is known as the Queen Annes sign based on a portrait of Anne of Denmark, , James 1st Queens Consort, although it is not clear that she was ever hypothyroid!

Mechanism Of Thyroid Related Hair Loss

Normally, the thyroid gland function is to release triiodothyronine and thyroxine hormones into the bloodstream to regulate wide range of body functions, including the regulation of central nervous system and metabolism. An overactive thyroid gland apparently stimulates the production of excess of hormones, which tend to boost the metabolic rate by assisting the system to drive energy into the cells. An over-functioning thyroid gland increases the heart rate, nervousness, perspiration, including hair loss. Moreover, the hormonal imbalance ceases the growth of hair from the hair follicles. Hence prescription thyroid hormones should be taken daily to correct the problem as the hair regrowth occurs when the body produces appropriate hormones to promote hair formation.

Hair related signs in thyroid disorders

Some of the commonly experienced hair related signs during thyroid disorders are as follows:

Is It Possible To Prevent Or Stop Hair Loss

Just like with other health-related problems, it is all about the early diagnosis. Besides recommending the adequate treatment for your condition, the doctor can also help you minimize hair loss. The goal of the treatment is to restore the balance in thyroid hormone production. Healthy hormones mean healthy hair growth! Hypothyroidism patients receive medications that support the production of thyroid hormones while individuals who struggle with hyperthyroidism get anti-thyroid drugs.

How Does Hypothyroidism Cause Hair Loss

Hypothyroidism is the condition in which the thyroid gland does not produce enough thyroid hormone. Thyroid hormones are responsible for regulating the body’s metabolic rate including controlling heart, muscle and digestive functions, brain development, and bone maintenance. When not enough thyroid hormone circulates in your body, your cells cannot keep up with normal processes.

Low thyroid hormones can interfere with the hair growth cycle by shortening the anagen phase and delaying the start of a new follicle from growing. Thus, more hair than normal can be in the resting phase, making your hair thinner. Low thyroid hormone levels can also cause your hair to become brittle and dry, making it look even more sparse.

Are There Other Causes

Nutritional deficiencies are definitely something that you should look into if you have hair loss.

Iron deficiency anaemia can cause hair loss so always check your iron levels. Dr Philip Kingsley, Trichologist, states that ferritin levels also need to be checked and that, Even if the ferritin is within the normal range, the level may still not be adequate for optimum hair growth.

He states, Hair loss due to low ferritin is one of the most common types of hair loss we see in women. 3 Be careful when supplementing with iron as it can be toxic Toxic “something poisonous, very harmful or bad” .

B12 deficiency may cause hair loss although evidence is sparse.4

Biotin deficiency has also been reported as a cause of hair loss and some people found that it improved after taking supplements. You need to be aware, though, that taking biotin Biotin “a vitamin found in small amounts in many foods such as eggs, milk, or bananas. Commonly used for hair loss, brittle nails, nerve damage, and many other conditions” can show skewed levels in your test results. 5,6

Other vitamin deficiencies that may play a role in hair loss are vitamin C, vitamin D and vitamin E.4 The mineral, zinc, also plays a part in hair loss.4,5

Taking vitamin supplements may not always be helpful, though. Too much Vitamin A has been reported as causing hair loss so be careful with this vitamin.4

Hypothyroidism/hyperthyroidism And Hair Loss

Levothyroxine & Hair Loss – 3 CAUSES + HOW TO STOP IT

Hair loss is a common symptom of both thyroid disorders. For instance, a research study showed that hypothyroidism isnt only associated with skin changes, but hair growth suffers too. The study used mice and found that those lacking TR1 and TR, the main thyroid hormone binding isoforms, experienced disrupted hair cycling. This impaired hair growth cycle was strongly linked to a decline in follicular hair cell proliferation.

Additionally, Egyptian scientists carried out a study to investigate whether alopecia areata was linked to thyroid autoimmunity and thyroid function abnormalities in 50 participants. They discovered that subclinical hypothyroidism was recorded in 16% cases. There were major differences between hypothyroidism patients and controls regarding T3 and T4 levels. Based on these results, scientists concluded that patients with alopecia should also be screened for hypothyroidism as these two conditions are connected.

When the thyroid produces an insufficient amount of much-needed hormones, the body is unable to metabolize protein properly. This is bad if you want to long luscious hair because these proteins is vital for hair growth. At the same time, acid levels in your stomach decline and dont allow you to absorb essential nutrients that support healthy hair growth process.

    Structure Of A Hair Follicle

    Human hair grows out of a tunnel-like structure called a hair follicle, which is embedded into the skin . These follicles are present all over the body, but they are most densely concentrated on the scalp, which contains nearly 100,000 follicles on average.

    A hair follicle starts as a tiny pore on the epidermis and extends like a narrow canal deep into the dermis. A sebaceous gland underlying the scalp is attached to the upper part of the follicle from the outside. This gland supplies oil or sebum to the hair follicle to keep the hair naturally moisturized.

    The lower end of the follicle is onion shaped and called the hair bulb. It is here that living hair cells called keratinocytes proliferate to construct the hair shaft.

    The hair bulb is surrounded by the dermal papilla, which is enriched by several blood vessels that supply nutrients, oxygen, and essential hormones to sustain hair cell division and thereby healthy hair growth.

    How Thyroid Hormones Cause Hair Loss

    Iron deficiency 12 important signs

    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.

    Stress management and nutrition can play a key role in hair health, too.

  • Check and boost your iron intake. Low iron causes low ferritin, a blood protein associated with hair growth. Thyroid issues also cause low ferritin, which means youll want to get your ferritin and iron levels checked at the same time as your thyroid.
  • Make sure you are getting enough protein, as protein is a building block for hair.
  • Try a multivitamin with biotin. A, C, E, and B vitamins, zinc, copper, and CoQ10 can also contribute to hair health. Biotin, part of the B vitamin family, is an absolute essential and you can find hair, skin, and nails biotin supplements pretty much everywhere.

    What If You Have Thyroid Hair Loss

    Because the hair growth cycle IS months long it is easy to misinterpret the cause of hair loss which may actually appear several months after the initial cause. This can lead to people wrongly blaming their thyroid medication rather than the medical condition. Unfortunately if they then stop the medication the hair loss will become more significant.

    It is very rare indeed for anti-thyroid drugs or treatment to cause hair loss.

    In most cases, loss of scalp or eyebrow hair is temporary but regrowth can take several months whilst the medication normalises the cycle of regrowth. When it does grow back it is possible that it may be different in both texture and colour.

    The loss of hair can obviously be extremely traumatic, but the key is to be patient and not to be taken in by miracle cures. You can also do several things to help you get through this most challenging time

    • Join a local alopecia support group
    • Or find help via an alopecia forum of the Facebook Group @AlopeciaUK

    • Dont stress your hair – avoid straighteners and use wide tooth combs
