Eyebrows are arguably one of our most distinctive facial features, framing the eyes, giving structure to the face, and ultimately setting us apart from the crowd. While some are blessed with thick, full eyebrows others have to find more creative ways of taming, and shaping them. Either way, we credit our eyebrows for enhancing so many beauty looks, but what happens when you start to notice them changing shape on their own?
Despite our best efforts, its not uncommon to see your eyebrows begin to thin out and appear more sparse. In fact, dermatologist, Anar Mikailov estimates that in a typical week at his office, about 15 percent of his patients have thinning eyebrows. “Be gentle and kind to your eyebrows,” says Dr. Mikailov. “Minimize the number of products you use on your hair, be gentle with washing, and minimize sunburns.”
Sometimes, the answer is just taking it easy on your grooming habits. But there are some bigger, more complicated causes to watch out for. Ahead, we asked three dermatologists what the most common reasons are for eyebrow thinning and what you can do to prevent hair loss.

Over-plucking or Grooming
When you spend time in front of a mirror—especially a magnified one—it’s easy to overthink every last hair. It only takes one mis-pluck to throw the balance off, and before you know it, you’re over-correcting your arches until theres barely anything left.
It’s happened to the best of us, but luckily, one aggressive pluck session won’t ruin your arches for good. But doing it too often could cause long-term thinning. “It’s repeated trauma that can ultimately cause the root of your hair follicle to stop functioning properly,” says Dr. Mikailov. “Ultimately the stem cells that create new hair stop regenerating.”
If your brows are suffering from over-grooming, the first step in rehab is easy: put down the tweezers. Let your eyebrows grow back the best they can and stop attacking every errant hair if you know you won’t be able to help going hunting for more.
If you still have some thin patches or the regrowth just isn’t happening, there’s still hope. Dermatologist-prescribed Latisse and Rogaine can both help fill out-over plucked brows. Dr. Mikailov also recommends Folliflo by Cell Accel Eyelash and Brow Enhancing Serum ($27), an over-the-counter serum that is formulated with castor oil and panax ginseng to help stimulate hair growth naturally.
Those who are pregnant are urged to avoid any products with castor oil, as it can induce labor. As with any skincare product during pregnancy, it is best to check with your doctor before using.

Underlying Skin Conditions
Those with eczema or psoriasis will likely not be surprised to hear this—these chronic skin conditions can exacerbate hair thinning, both on your scalp and your brows. If you do have one of these conditions, you’ve likely already noticed it in the form of itchy rashes. If you don’t think you do, but you’re experiencing itchy, inflamed, flaky skin under and around your brows, it might be worth having a dermatologist look at it. Any scratching or rubbing that youre doing might cause hair to fall out.
Once you nail down whats causing the skin irritation, stopping hair loss is all about treating the condition. “I always look to see if there is any underlying skin condition affecting the eyebrows, surrounding skin, and also scalp,” says dermatologist Robin Blum. “I also use a handheld device called a dermatoscope to get a better visualization of the hair follicles and surrounding skin. If there is inflammation in the area of hair thinning, that can be treated with either topical, intralesional, or oral steroids."

Auto-immune Disorders
Auto-immune disorders like hyper- and hypo-thyroidism or androgenetic alopecia can also cause eyebrow thinning. While these conditions mostly surface in middle age, it can also be genetic and hormone-related, and not everyone is the same. “The most important thing I do when someone comes to me for eyebrow thinning is to take an in depth medical assessment of the thinning,” says Dr. Blum. “I take a full medical history and ask about family history as well.”
In this case, early detection is best. “Treatment can be difficult, so addressing it early is recommended,” says dermatologist Cheshana Kindred. “This is one of the few cases in which treating the underlying condition does not automatically reverse thinning eyebrows.” Once you’ve addressed your health (which should always be your first priority), a hair growth treatment like Latisse could help to regrow lost brow volume.

Aging
Aging affects us all in different ways, but loss of hair density is a very common occurrence. With time, our hair follicles aren’t regenerating or maintaining hair as well and you may notice a thinner or more brittle quality to your hair. Hormones play a role here, too. “People typically start to see thinning in their 40s with the decline of their testosterone or estrogen levels,” says Dr. Blum.
We can’t stop time, but we can find ways to fill out brows that have lost a little volume over the years. Dr. Blum recommends tinting the hair for a darker appearance, or looking into microblading—a kind of semi-permanent makeup that mimics the look of individual hairs with fine, tattooed strokes.

Nutritional Deficiencies
When your body is deficient in necessary vitamins, it tends to draw what it can from non-essential functions.1Hair growth is one of those functions. For example, vitamin D deficiency is common in American adults and can cause eyebrow thinning. Additionally, Vitamin D is needed to build bone density, control infection, and lower the risk of heart disease and certain cancers. Your body would much rather protect you from disease than make sure your brows are looking good, so it takes vitamin D from your hair follicles to keep everything in working order.
Other common deficiencies that your body might be compensating for are zinc, selenium, and iron. “You’ll want to seek out a nutritional diet with essential vitamins, or supplement the diet with the appropriate vitamin,” says Dr. Blum. That could mean making a little more time for sunshine and eating more red meats and legumes, or it could mean making a daily supplement (like the Foligain Stimulating Supplement for Thinning Hair ($28), which contains hair-thickening super ingredients like folate, biotin, and zinc) part of your routine. Your hair wont grow back overnight, but you should notice thinning start to slow.

Stress
It can be frustrating to learn about all the ways stress can wreak havoc on our minds and bodies. Unfortunately, hair loss is another unexpected side effect of being overworked or not spending enough time on mental health and mindfulness.
When you’re stressed out or upset, your body produces a stress hormone called cortisol. While very helpful for giving us the adrenaline boost we might need to outrun a predator, it can cause some non-essential functions like hair growth to kick into “rest mode.” While you can’t get rid of cortisol (nor would you want to), you can learn to manage it. “If the cause of your eyebrow thinning is stress or picking, it’s best to seek out stress management therapy,” suggests Dr. Blum.

Trauma
If you have experienced physical or emotional trauma of any kind, that too can be the reason for your thinning brows. This condition is known as telogen effluvium, or sudden hair loss. According to derms, telogen effluvium is reversible and can be treated with over-the-counter medication and management of stress. If hair doesnt grow back within three to six months, you and your doctor might need to discuss a hormone replacement therapy.
Yes! Depending on the root cause of your eyebrow thinning, prescription creams, medications, or simple over-the-counter products can help you rehab your brows and encourage thicker growth.
It depends. If, after reading this, you’re pretty sure your eyebrow thinning is from over-tweezing and over-waxing, you can start by giving grooming a rest. But there are certain things you should look out for. “Promptly see your doctor if you notice sudden eyebrow thinning or thinning on just one eyebrow,” says Dr. Kindred.
If you’re experiencing eyebrow thinning, you could have low levels of vitamin D, zinc, and selenium.
