Why Are My Eyebrows Falling Out?

- Reviewed by: Dr. Jae Pak, M.D.

It’s a question that too many people end up asking at some point: why are my eyebrows falling out? A sizable portion of the population deals with this problem, especially as they age.

Seeing eyebrows become sparse and patchy is cause for concern, and because there is no singular cause, identifying the core issue can be a challenge. Eyebrow hair loss typically occurs for a variety of reasons combined with genetics, and aging, so we urge patients to consider all the possible causes at hand.

To help clarify the situation and point you towards an effective treatment plan, we’ve compiled a list of reasons why eyebrows may thin with time. Each section contains an overview of a possible cause, then offers tools and tactics to counteract them.

This article will lay everything out in a practical format so that you can find the underlying cause of your eyebrow hair loss and remedy the situation as soon as possible. Let’s begin.

Lifestyle and Nutrition

The cause of your eyebrow woes may be as simple as the lifestyle choices you make every day. When your body is not operating in peak condition, it tends to start deteriorating physically — even in minor ways like brow hair loss.

Many patients have struggled with eyebrow thinning due to unhealthy lifestyles, only to see a significant turnaround when they improved their core habits. Here are some key points to consider.

Healthy Living

With an active lifestyle fueled by clean, natural foods, you put yourself in the best position to be healthy and happy — and grow great brows as a bonus. You likely know the basics already – exercise and a balanced diet are essential, with deep sleep for recovery as well.

We’re not here to map out the rules for your next health kick, but it’s worth sharing that the best brows are developed when you’re maximizing blood flow, prioritizing protein and healthy fats, and giving your body what it needs to thrive.


Even those who follow a super-healthy diet often find that supplements help fill in the gaps where food falls short. Concerning hair and brow loss, nutrient deficiencies are a common culprit, so creating a hair-growth supplement stack might be a wise move.

Be on the lookout for capsules including the “big three” hair growth compounds — collagen, keratin, and biotin. Add in a multivitamin, some healthy krill, or cod oil, and you’ve got a solid stack that could boost brow growth.

Consistency is key with supplementation, so be sure to stick with it for several months (every day) before assessing your results.

Stress Reduction

It’s far from a myth that stress can make your hair fall out — and not just the hair on your head! Brow hair can start to thin after periods of chronic stress in which your cortisol levels are elevated, and your body is in constant low-level fight-or-flight mode.

Our modern world may be stressful, but we also have many tools to help us relax and keep that stress down. Manage your life to reduce unnecessary stress and prioritize rest when need be.

When you start living with less stress, you’ll find that hair growth comes more naturally, and your body and mind simply operate better in all areas.

Illness and Medication

Since the systems of the body are so closely interconnected, it’s not uncommon for illnesses to result in eyebrow hair loss as one of many unexpected side effects.

In other words, when eyebrow hair falls out, there’s usually something else going on behind the scenes that the body is fighting, whether it’s an infection, an autoimmune condition, or something even more serious.

This is one of many reasons why working with a hair loss professional is the best course of action when responding to brow hair loss. Only the most experienced physicians can understand how various illnesses and medications interact with brow health and can set you on the right track.

In the meantime, these tips should help you organize your priorities and keep brow loss to a minimum even as you combat illness and side effects.

Address the Problem

While some very rare conditions cause permanent hair loss on the brows, most medical events lead to a short-term loss that can be restored shortly after that.

That’s why your top priority should be to address the illness itself before concerning yourself with aesthetic issues like brows and hair. The most common example is chemotherapy — we accept that eliminating cancer from the body is more important than hair and can look forward to restoration once treatment is complete.

The concept applies more broadly, as well. Whether you’re dealing with a bacterial infection, a contagious virus, or a skin issue like eczema or psoriasis — fix the root problem first, then establish a game plan to grow your hair back the right way.

Balance Hormones

Human hormones are so complex that the field of endocrinology is still seeing breakthrough discoveries all the time. With respect to eyebrow health, we must balance hormones to avoid thinning and maximize growth, especially as we advance in age.

We can combat most hormonal issues through lifestyle adjustments and perhaps thyroid medication, but additional exogenous hormones might be necessary to achieve the balance you need.

This shouldn’t be your first plan of attack when addressing eyebrow hair loss, but it’s a common enough cause to consider.

Stimulation Shortage

To some degree, our hair, skin, and nails are only as healthy as they need to be. This is why direct stimulation and grooming are so important to look fresh and promote growth and longevity in areas like brow hair.

When we fail to stimulate these systems properly, our bodies no longer prioritize their health, and other issues can come into play. This is why you should avoid tweezing and plucking and instead try trimming and other forms of direct stimulation.

Here are some suggestions that can make a big difference.

Healthy Oils and Massage

Olive oil, castor oil, even coconut oil – these household staples contain tons of healthy nutrients that can be applied directly to the brows for great effect.

These oils serve to moisturize the area prone to chronic dryness, and they also facilitate massaging the brow to maximize these efforts.

It only takes a couple of sessions each week to dramatically improve the look and feel of your browline with an essential oil massage, so add this to your routine ASAP.


Many different techniques fall into the category of collagen induction therapy, a technique that promotes the production of healthy cells and enzymes in skin and hair where applied.

Microneedling is a familiar example, using derma-roller tools to create tiny punctures in the skin that release collagen, elastin, and other helpful compounds that heal and strengthen follicles.

The next step up is microchanneling, a medical-grade method using advanced implements administered by licensed pros like Dr. Jae Pak, M.D.

Exfoliation and Cleansing

Brow hair is particularly susceptible to collecting dirt and oils that can clog pores and lead to hair loss. The answer to this problem is exfoliation, which should be performed at least once a week for best results.

By exfoliating frequently, you clear the brow of all dead skin cells and other material that may be lingering behind. The result is a healthier, cleaner brow line that is more conducive to growth and healthy hair.

More Tips and Options

While there are many potential causes for brow hair loss, it’s important to not lose sight of the many possible solutions in today’s world. Here are some final tips you can use to keep your brow hair thick and strong.

Strategic Cosmetics

Overdoing the makeup or fillers is usually not a good idea, but these tools can be very useful when implemented on occasion.

Find cosmetics products that complement your natural tones and won’t irritate the skin. As you wait for your natural hair to grow, these solutions can be highly convenient.

Advanced Therapies

New treatments like low-level light therapy are becoming more popular for brow hair growth in particular. Other solutions like Bimatoprost (Latisse) may be effective in promoting brow growth as well.

This type of treatment requires ongoing visits to clinics and can add up in cost but may be well worth the effort.

Brow Transplant Surgery

The booming popularity of eyebrow transplants shows that this procedure gets real results. Hair is extracted from the back of the scalp and grafted to the brow with technical and artistic expertise, and transformative results are attained within a few months.

Talk to a leading brow transplant clinic today to see if this procedure is right for you.
