If you notice thinning or some gaps in your eyebrows, then you might have eyebrow hair loss. Eyebrow hair loss is a condition that can affect both men and women. It can sometimes occur on one and sometimes on both sides.

Eyebrow hair loss could cause itchiness and dry skin; however, it is not a serious condition. There can be many factors behind the eyebrow hair loss. Those factors could be hormonal disorders, diet, and various skin conditions. Let’s take a deeper look at the causes of eyebrow hair loss. This should help you identify the cause and treat it accordingly.

Causes of Eyebrow Hair Loss


It is normal for people to lose their hair as they get older. This is also true for the hairs on your eyebrow. 

Hormonal Disorders

Shifts in hormone levels could cause hair loss. The most common cause is the imbalance of thyroid hormones. Both hyperthyroidism and hypothyroidism could cause eyebrow hair loss. Consult your doctor to find out whether you have imbalances in your thyroid levels. You can balance your thyroid levels with the help of the medications your doctor prescribes. Once the thyroid levels are balanced, your hair loss should stop.

Autoimmune Disorders

Autoimmune disorders could cause your immune system to attack your own body cells accidentally. When your immune system attacks the cells related to the growth of your follicles, this will cause hair loss. There are various autoimmune disorders that cause hair loss. These are:

  • Alopecia areata
  • Frontal fibrosing alopecia
  • Discoid lupus erythematosus

Consult your doctor for more information.

Skin Diseases

The health of your skin affects the health of your hair follicles. Certain skin diseases such as atopic dermatitis, psoriasis, and seborrheic dermatitis could cause eyebrow hair loss. 


What you eat matters. Everybody knows that eating healthy is good for your body, but few know that it also affects your hair. Not getting enough nutrients beneficial for your hair can cause hair loss. Be sure to get enough fatty acid, biotin and zinc into your body.

Side Effects of Medications

Some medications could cause hair loss as a side effect. Check the instructions for your medications. If you are suspecting that your medications are the main cause, then speak with your doctor. Your doctor should be able to recommend alternative treatments for your condition.

Hereditary Causes

Check your family members. If you have a family member that is struggling with the same issue, then it means that your condition is genetic. 

Treating Eyebrow Hair Loss

Before you do anything, you should first consult your doctor about your condition. 

There are some medications, such as minoxidil and finasteride, that are proven to be effective against hair loss. Other than that, you could always have a hair transplant. Thanks to the microblading technique, you can once again have fuller eyebrows.
