What is Eyebrow Loss? What Causes?

Eyebrow loss, also known as eyebrow hair loss or eyebrow thinning, refers to the loss of hair from the eyebrows. This can occur gradually or suddenly and may affect one or both eyebrows. Eyebrow loss can be caused by a variety of factors, including genetics, medical conditions, hormonal imbalances, and over-plucking or other forms of hair removal. It can also be a side effect of certain medications or treatments like chemotherapy. Eyebrow loss can be a source of cosmetic concern for some people and may impact their self-esteem. Treatment options for eyebrow loss depend on the underlying cause and may include topical or oral medications, eyebrow transplants, or cosmetic procedures like microblading.

Eyebrows do not spill when there is no reason. If the eyebrows have been spilled and this continues, there may be many reasons for this. Less work of thyroid glands, eyebrows due to stress, eyebrows caused by atopic dermatitis, spills caused by fungal and eczema, and scalp hair loss in leprosy can occur.

What Causes Eyebrow Loss?

Eyebrow loss occurs due to many reasons. There are many reasons for eyebrows, especially in women. These;

  1. Genetics: Just like hair loss on the scalp, eyebrow hair loss can be hereditary. Some people may have a genetic predisposition to thinning eyebrows.
  2. Medical conditions: Certain medical conditions can cause eyebrow loss, including autoimmune diseases like alopecia areata, thyroid disorders, and fungal infections of the skin.
  3. Hormonal imbalances: Hormonal imbalances, such as those that occur during menopause or pregnancy, can lead to eyebrow hair loss.
  4. Over-plucking or other forms of hair removal: Over-plucking or aggressive hair removal techniques, such as waxing or threading, can damage hair follicles and cause permanent hair loss.
  5. Medications and treatments: Some medications, such as chemotherapy drugs, can cause hair loss, including eyebrow hair loss, as a side effect. Certain cosmetic treatments like chemical peels or laser hair removal can also lead to eyebrow hair loss.
  6. Nutritional deficiencies: In some cases, eyebrow hair loss can be a sign of a nutritional deficiency, such as a lack of biotin, vitamin D, or iron.
  7. Aging: As we age, hair growth can slow down, and eyebrow hair may become thinner or sparser.

It is important to identify the underlying cause of eyebrow loss before pursuing treatment options, as this can help determine the most effective approach to restoring eyebrow hair.

Continuous Brow Removal

Continuous brow removal, also known as excessive brow plucking or over-tweezing, is a common cause of eyebrow hair loss. It involves the continuous removal of eyebrow hair by plucking, waxing, or threading, which can eventually lead to permanent hair loss.

When eyebrow hairs are plucked or removed repeatedly, the hair follicles become damaged, which can eventually prevent hair growth. Over time, the constant removal of hair can lead to thinning eyebrows or even bald patches in the eyebrow area.

Continuous brow removal can also lead to a condition called traction alopecia, which is hair loss caused by constant tension or pulling on the hair. This can occur with over-tweezing or other aggressive hair removal techniques.

If you have experienced continuous brow removal and are now noticing thinning or bald patches in your eyebrows, there are a few things you can do to promote eyebrow hair growth. One option is to stop removing eyebrow hair altogether and allow the hair to grow back naturally. In some cases, this may take several months or longer.

There are also several products available that can help promote eyebrow hair growth, such as serums containing ingredients like biotin, castor oil, or peptides. Additionally, there are cosmetic procedures like microblading or eyebrow transplants that can help restore the appearance of fuller eyebrows. However, it’s important to talk to a qualified professional before pursuing any cosmetic procedures to ensure that they are safe and appropriate for you.


Chemotherapy is a treatment for cancer patients. This treatment is a treatment to prevent cancer growth by controlling cancer cells. According to the type of cancer, the drugs applied, and clinical oncologists determine the frequency of treatment. The aim of cancer therapy is the complete elimination of cancer cells. The treatment aims to prevent the growth and proliferation of cancer cells and to ensure the complete removal of tumor-causing cancer.

Although chemotherapy is a cancer disease treatment, it has some side effects. The most important of these is the negative effects on the skin and nails. Redness of the skin, redness of the nails, and redness color changes occur in the skin and nails. However, these side effects end soon after the end of treatment. Hair and eyebrows are observed during chemotherapy. Even hairs and eyebrows are completely poured. In this process, the hair cut complete is more psychologically relaxing. Because as long as the treatment continues, the hair will be cast in clusters, and this image has a very negative psychological effect on the person. However, spills on the hair and eyebrows occur again a couple of months after the end of the treatment, even in some people.

Thyroid Insufficiency

Thyroid insufficiency, or hypothyroidism, can affect eyebrow hair growth and lead to eyebrow hair loss. The thyroid gland produces hormones that play a critical role in regulating the body’s metabolism, including the growth and maintenance of hair.

In hypothyroidism, the thyroid gland does not produce enough thyroid hormone, which can result in a slowdown of many bodily functions, including hair growth. One of the symptoms of hypothyroidism is thinning hair, including eyebrow hair loss.

Eyebrow hair loss in hypothyroidism may occur gradually over time or may be sudden. It can affect one or both eyebrows and may result in sparse or patchy hair growth. Other symptoms of hypothyroidism, such as fatigue, weight gain, and dry skin, may also be present.

Treatment for hypothyroidism typically involves thyroid hormone replacement therapy, which can help restore normal thyroid function and alleviate symptoms like eyebrow hair loss. In some cases, eyebrow hair loss may not be reversible, and cosmetic procedures like microblading or eyebrow transplants may be necessary to restore the appearance of fuller eyebrows. It’s important to talk to your healthcare provider if you are experiencing eyebrow hair loss or other symptoms of hypothyroidism.

Hansen’s Disease

Hansen’s disease, also known as leprosy, is a chronic bacterial infection that can affect the skin, nerves, and other organs of the body. One of the possible effects of Hansen’s disease is eyebrow hair loss.
