However, there are reasons why brows may become more uneven with time, which may lead to a more dramatic difference. Even though uneven brows aren’t necessarily bad, it’s perfectly reasonable if you may want to try to get your brows to look more similar. Here, what to do about it. However you can still fake an even arch or fill in sparse areas if you choose, so skip to the next section if you want a few expert tips. Giving yourself an original brow shape from scratch is no easy task, Healy says. Instead, you should only opt for DIY maintenance, which simply means maintaining the brow shape that a professional has previoulsy defined for you. The reason overplucking can create uneven brows is because it takes away too much hair, which can create uneven length, shape, and even empty patches. The fix: Put the tweezers down. Consult a brow specialist to help you create a base shape that you can maintain at home and let them grow out (more on brow growth in a bit). So if your brows look uneven, it could be reflecting the state of your underlying skin. What’s more, your bone structure inevitably changes with age, too. “Our bones also degrade over time as well, creating a gap between the muscle and the bone which can also exacerbate the asymmetry of the brows,” he adds. Not to mention your hair naturally becomes more sparse overtime. Thinning of the brow hairs is completely natural, however you can support growth via serums. Again, keep reading for the breakdown on growth. “There are certain muscles in the frontalis, the forehead muscle, that’s job is to keep the brow down. When botox is applied prohibiting movement in this muscle, the brow can actually float a little bit,” he explains. If this has happened to your brows, it may manifest into uneven brow levels—read: one brow raising higher than the other. Luckily, botox doesn’t last forever, so the uneven brow will go back to normal with time. “It’s always best to have a conversation with your medical professional and mention that your brows are of concern and you want the doctor to keep your brows in mind when providing botox treatment,” Healy notes. One more thing to keep in mind: It takes anywhere from one to two weeks to see the full effect of botox. So if you notice your brows begin to look uneven a few days in, go back to the office you received your botox at and request a correction. “This happens more often than people realize,” Healy says. What’s more, sleeping on one side actually affects the rate at which your brow hairs shed. “The increase in friction can cause the brow hairs to shed faster, especially in the tail of the brow,” Healy explains. In turn, this can cause thinning of the brow and an early cut-off. “However, if you naturally have very strong, conditioned brow hairs that are well-rooted, this shouldn’t be as big of a problem,” he notes. Yep, just another reason to add a brow serum to your beauty routine. If you’re truly concerned about how sleeping on one side will impact your skin or brows, you can try to switch to sleeping on your back. The transition isn’t always easy, but it is certainly possible. Healy also recommends investing in a silk pillowcase. This will help decrease friction and prevent threads tugging at the brow hairs. Plus, your hair and skin will thank you, too. When searching for the best brow serum, consider the follow ingredients A+ additions: If you can’t keep up with regular appointments, whether it’s because of your schedule or the price range, ask your expert how to maintain your brows at home. They might even set you up with some must-have tools and, most importantly, tell you what not to do. What’s more, brow experts can help you determine which mode of hair removal will be best for your brows. Here’s a quick breakdown of each of the most popular: Microblading creates hairlike strokes, while microshading mimics brow powder. The looks vary, and which one is more natural depends on how it is performed and your personal preference. As a rule of thumb, those who love brow pencil will likely fancy the look of microblading, while a brow powder die hard will probably lean toward microshading.

Stress hair loss is a very real situation (read more in our guide to stress-related hair loss), and shouldn’t be discounted when you’re experiencing thinning in the area. Dealing with hair loss caused by stress can be difficult to navigate—especially because you have to get to the root of the cause first, which is stress. However, it is doable, so don’t let thinning brows add to your stress in the process. Just to be safe, visit your doctor if you notice a dramatic change in the density of your brows. This is similar to the facination with facial symmetry—an angelic bone structure and perfectly aligned features layout may seem awe-worthy, but oftentimes it’s less symmetrical faces that seem more interesting, and more beautiful.
