Eyebrow Hair Loss Causes

By narrowing down the cause, you and your doctor can find the right treatment to help prevent, reverse, or minimize hair loss. Specific causes for brow loss include:

Alopecia areata

The same autoimmune disease that is oftentimes responsible for scalp hair loss alopecia areata can also affect your eyebrows. In this case, your immune system mistakenly targets and attacks your eyebrow follicles, thereby slowing or halting eyebrow hair production.

According to the National Alopecia Areata Foundation (NAAF), alopecia can also affect fingernails and toenails. People often use minoxidil and corticosteroids together to treat alopecia areata.

Other autoimmune disorders may also result in eyebrow loss, such as the Graham-Little Syndrome, some forms of Lupus, localized scleroderma, and the Parry-Romberg syndrome.

Nutritional deficiencies

Nutritional deficiencies could also cause sparse brows. Your body requires certain nutrients to create healthy hair—a healthy balance of carbohydrates, proteins, fats, amino acids, vitamins, and minerals. The food a person eats has a substantial impact on their skin and hair health.

Since some of these nutrients sustain and influence hair growth, but nutrient deficiency could result in hair loss. For example, a deficiency of vitamins C, E, B-12, D, iron, cysteine, and/or omega-3 fatty acids could trigger hair loss, including in the eyebrows.


Skin conditions, such as eczema and psoriasis can interfere with proper hair growth. Any dermatitis can block hair follicles from growing hair normally. Thinning brows are also a common side effect of other conditions such as atopic dermatitis (contact dermatitis), eczema, and Seborrheic dermatitis, which scientists believe is caused by a fungus or by an overproduction of oil in the skin, unlike Hansen’s disease caused by a bacterial infection.

A dermatologist can recommend medications and topical medication treatments to help.

Thyroid disease

The thyroid gland, located in the front of the neck, produces hormones that regulate your metabolism. When it produces too much or too little of a hormone, your body’s normal processes can be disrupted. Both overactive and underactive thyroid glands can lead to hair loss.

Other symptoms of thyroid disorders include dry, pale skin or moist, velvety skin swelling in the neck (a goiter ), coarse, dry, and brittle hair, a dry, itchy scalp thick, dry, brittle nails.

Excessive stress or anxiety

Psychological issues are known to contribute to eyebrow hair loss. If you have recently experienced a traumatic event or major lifestyle change, this may be the root cause.

Telogen effluvium (TE)

This refers to a temporary but dramatic loss of hair when your normal hair growth cycle is interrupted. This can be due to stress, changes in your diet, skin condition, medications, hormonal, or other changes in your body chemistry.

Over plucking

This practice creates minor trauma to the follicle, resulting in the hair no longer growing in that spot. Eyebrow hair follicles tend to be sensitive to removing the hair, so plan your brow shape and try not to get carried away tweezing.

Scar tissue

It can result from trauma, burns (chemical or thermal), and skin conditions typically involving problems with the immune system attacking the body’s tissues. This may be due to frontal fibrosing alopecia (where scarring and hair loss occur on the scalp and the eyebrow region for genetic, autoimmune, or environmental reasons).


Generally starting in our 40s, as levels of estrogen in women and testosterone in men dwindle, both genders may start to experience thinning of hair on the scalp and in the eyebrows as it is unfortunately natural to experience some hair in older age, due to an overall decline in hair follicle quality.


Chemo is specifically designed to affect all rapidly dividing cells, including hair follicles. Therefore, chemotherapy can stifle hair production in the brows.

Eyebrow Hair-Loss Prevention

If one or both brows are thinning, it could be due to infection, skin conditions, genetic conditions, hormonal changes, or an overactive immune system. Eat plenty of lean protein, fruits, and vegetables. Find ways to relax and reduce stress, such as massage or meditation.

Please resist the urge to over-pluck your eyebrows or use harsh chemicals near them. Protect your brows with a dab of Vaseline if you need to use hair bleach or dye, tretinoin (Retin-A), hydroquinone, or glycolic acids.

How Can I Get My Eyebrows Back?

Treatment options range from medications and creams to alternative therapies and cosmetic procedures. However, there are some things that you can do at home that may help you grow your eyebrows.

A balanced diet

Not getting enough biotin can result in Trusted Source thinning hair and a loss of body hair.

Avoid plucking, waxing, and threading.

We also see thinning eyebrows, especially in women, due to too much tweezing or waxing earlier in life.

If you want your eyebrows to grow back, you should avoid tweezing, waxing, or any other form of hair removal. This gives your eyebrow hairs the chance to grow fully.

Castor oil

There haven’t been many scientific studies to prove it can regrow hair, but the main compound in castor oil — ricinoleic acid — has been linked to hair regrowth. At the very least, it can keep your brows moisturized, which may help prevent breakage.

Eyebrow serums

There are some eyebrow serums available that are said to help eyebrows grow faster and thicker. While these claims haven’t been scientifically proven, they may still be worth a shot. However, it’s important to remember that frequent serums will help stimulate hair growth over time.

Bimatoprost (Latisse)

Latisse is a medication approved by the U.S. Food and Drug Administration (FDA) to promote eyelash growth that has shown promise as a way also to grow eyebrows. Though not yet approved for use on the eyebrows, there’s evidence that bimatoprost 0.03% solution can help regrow eyebrows when applied once or twice a day.

Topical treatments and cosmetic processes can also help restore hair growth. Microblading is a cosmetic tattooing procedure that fills in thin eyebrow areas to make them look fuller, unlike a traditional tattoo, which is a permanent solution to restoring thin brows. The coloring from microblading may last for up to 3 years. This is because microblading uses different tools and a smaller amount of pigment.

Eyebrow transplant restoration is similar to scalp hair replacement. It involves removing a section of skin from a location with ample hair and transplanting hair follicles to the sparse eyebrow area. Eyebrow transplants have been known to have exceptional results, particularly for alopecia. Studies show that 80% of patients with frontal fibrosing alopecia experienced “excellent hair growth” 6-12 months after the procedure.

Generally, you can expect a microblading session to cost (on average) around $400 to $600. This range is pretty consistent across the United States, and it’s worth mentioning that rates considerably less than this may be indicative of poor quality, so be sure to do your research.
