What Causes Hair Loss

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

There are several types of hair loss, with a wide variety of causes, from inheritance, to stress, to autoimmune disease.

Androgenetic alopecia is the most common type of hair loss. Usually, we see this as male pattern baldness or even female pattern baldness, with thinning primarily at the front and top of the scalp. This type of hair loss affects an estimated 50 million men and 30 million women in the United States. Many patients with androgenetic alopecia have a family history of this condition. It can begin as early as during a persons teen years, though risk does increase with age. In women, most hair loss of this form begins after menopause.

Alopecia areata is acute, patchy hair loss that is thought to occur when the immune system mistakenly attacks hair follicles. It occurs in about 2.1 percent of the population and affects both men and women alike. Its cause is likely autoimmune, and it can have a single episode or remission and recurrence.

Telogen effluvium is the most common type of hair loss we see with Hashimotos. Its primary causes include high fevers, childbirth, severe infections, chronic illness, severe mental stress, surgery, an over or under active thyroid gland, protein deficiency, nutritional deficiencies, and some medications. Its characterized by large clumps of hair falling out, usually while showering or brushing. It usually causes hair loss in a diffuse pattern, over the entire scalp.

Just How Thinning Hair Impacts A Ladys Confidence

Shedding hair can be a hard experience for anybody. Society links hair with young people and also beauty and the understanding that your hair is thinning can typically be demanding and have a large result on self-esteem. Culture also often tends to think about hair loss as a condition that impacts guys, which can make it more difficult for females to get the help they require. Study has actually shown that women can have a specifically hard time managing the self-confidence problems that are connected with hair loss.

Shouldn’t Levothyroxine Treat Hair Loss

Levothyroxine is a thyroid medication prescribed to treat low thyroid hormone levels. It is a synthetic form of thyroid hormone that mimics human thyroid hormone. One would imagine that once you correct low thyroid hormone levels, you would see an improvement in your hypothyroid symptoms, including hair loss. However, some people find their hair loss worsens when they start levothyroxine.

While this may be concerning, especially if you are already struggling with hair loss, rest assured increased shedding after starting levothyroxine is usually short-lived. Most people who notice more hair loss after starting levothyroxine find that it lasts only a month or two.

Additional shedding sometimes happens because the hormones need time to stabilize. The hair growth cycle takes time to adjust to changes in your system.

Rest assured, once you are on the correct dose of medication, most hair loss will cease. You should return to having a normal hair growth cycle unless there is another cause of your hair loss, like androgenic alopecia, for instance.

Yes Levothyroxine Can Cause Hair Loss

Hair loss can be one of the most frustrating symptoms associated with thyroid problems.

And thyroid-related hair loss is not just associated with low thyroid conditions but also high thyroid conditions as well.

Today, though, we will be focusing on hair loss associated with levothyroxine.

Levothyroxine is the most commonly prescribed thyroid medication out there right now.

In fact, it’s one of the most commonly prescribed medications in the United States.

Levothyroxine is used to treat patients who have LOW thyroid function so people who are taking this medication have hypothyroidism.

Levothyroxine is supposed to normalize thyroid function by providing your body with the very thing it needs if you don’t have enough thyroid hormone.

We know that one of the side effects of having LOW thyroid function is hair loss.

And with that in mind, we have a little bit of a problem:

How can it be the case that the very medication which is supposed to fix a low thyroid causes one of the symptoms associated with that very condition?

In other words, shouldn’t it be the case that treating a low thyroid will help your hair grow?

You would think so but it’s not quite that easy.

Why Does A Thyroid Imbalance Cause Thinning Hair

Your hair normally grows in a healthy cyclical pattern with most of the hair follicles growing while only a small number are resting. With a thyroid imbalance, this cycle can be thrown off, resulting in more hair follicles resting than growing and more hair falling out. Hair loss is a very common symptom of a thyroid imbalance.

But thyroid imbalances often arise slowly and remain unnoticed by women and their doctors in the early phases. Even with a lab test, your doctor may say everything is fine with your thyroid, even though you strongly suspect that something is wrong. This is because standard labs have a very wide range for what is normal in terms of thyroid test results.

So how do you know if your hair loss is connected to a thyroid disorder?

Both Hyperthyroidism And Hypothyroidism Can Cause Hair Loss

Hyperthyroidism is defined by an overactive thyroid. This can be a result of an autoimmune disorder called Graves disease. Hypothyroidism is defined by an underactive thyroid. This can be a result of an autoimmune disorder called Hashimotoâs thyroiditis. An overactive or underactive thyroid can cause overall hair loss as the thyroid has a big role in the development and maintenance of the hair follicles. Both hypothyroidism and hyperthyroidism can cause the hair to become dry, brittle, and prone to breakage. Severe casesA sustained imbalance in either extreme can cause severe hair loss. Not having enough or having too little thyroid hormone can be a huge shock to the system. A severe thyroid disorder can cause a scalp disorder called telogen effluvium causing the hair roots to go into an abnormal growth period of ârestingâ.

How Do Thyroid Problems Cause Hair Loss

Irregular thyroid function will cause testosterone in your scalp to convert to dihydrotestosterone . Eventually, DHT will shrink or even destroy hair follicles in various stages of growth. Both hyperthyroidism and hypothyroidism can cause hair loss, although the balding pattern will be different. With hyperthyroidism, your hair could become very fine and thin across most of your scalp. If you have hypothyroidism, you may lose hair on other parts of your body. One telltale sign of hypothyroidism is hair loss on the outside of the eyebrows.

In some cases, the treatment for thyroid dysfunction can also cause hair loss. Though rare, thinning hair can be a side effect of thyroid replacement drugs.

Hair shaft length measurements of vehicle/T3/T4-treated HFs were performed every second day on individual HFs using a Zeiss inverted binocular microscope with an eyepiece measuring graticule.

Seven-micrometer-thick cryostat sections of cultured HFs were fixed in acetone, air dried, and processed for histology. Masson-Fontana histochemistry was used for studying HF morphology as well as visualizing melanin pigment. HF cycle staging was carried out according to previously defined morphological criteria, and the percentage of HFs in anagen and early, mid, or late catagen was determined. Densitometric measurement of melanin staining intensity was performed with ImageJ software .

Autoimmune And Medical Conditions

Hyperthyroidism is caused by a number of diseases, Wright says, with Graves disease being the No. 1 cause. In people with Graves disease, the immune system produces antibodies that bind to thyroid-stimulating hormone receptors and tell your thyroid to produce more thyroid hormone. There is no off switch to this, Wright says, and it requires medical treatment.

  • Plummers disease: enlargement of the thyroid gland and overproduction of T4
  • Hyperfunctioning thyroid nodules: parts of your thyroid gland produce too much T4
  • Thyroiditis: inflammation of the thyroid

The most common cause of hypothyroidism is Hashimotos thyroiditis, an autoimmune condition that occurs when your immune system produces antibodies that attack your thyroid gland even in the absence of disease.

Hyperthyroidism can also result from thyroid nodules. These are lumps that develop inside the thyroid and sometimes begin producing thyroid hormones. Large lumps may create a noticeable goiter. Smaller lumps can be detected with ultrasound. A thyroid uptake and scan can tell if the lump is producing too much thyroid hormone.
