If you’ve ever desperately punched the words “eyebrow transplant” into Google, you’ve come to the right place. (And yes, the procedure is actually a thing.) Whether you were born with naturally thin eyebrows, have noticed an uptick in thinning as you’ve gotten older (this is natural and normal), or fall into my personal boat and were born with thick, perfectly satisfactory brows only to sabotage them with a pair of tweezers in the early aughts, the best eyebrow growth serums can work wonders in the lengthening and thickening departments.

Of course, results will vary person to person, and consistency—plus patience—is everything when it comes to these types of products, but non-prescription brow growth serums have come a long way in recent years. Many brands have formulated their own exclusive technology and ingredient blends—most of which contain potent botanicals, peptides, antioxidants, amino acids, vitamins, and strategic moisturizing agents to make the environment of the eyebrow area healthier and thus more conducive to new and accelerated hair growth

You probably already know where I’m going here, but not all eyebrow growth serums are made equally, and it’s important to choose formulas that not only are efficacious but also contain high-quality ingredients that won’t cause unwarranted irritation or sensitivity. (Trust us—we’ve seen our fair share of super-sketchy options out there.) Luckily, we totally have your back, and we’re listing 12 of our all-time-favorite eyebrow growth serums below that have the ratings, reviews, and ultra-loyal cult followings to back us up. Keep scrolling! 

There’s a reason this cult-loved eyebrow growth serum is number one on my list. It’s my personal favorite (sorry, bias will simply always win out here), and it is, in fact, so effective that I quite literally had to stop using it only a month or so in due to how fast and furious my previously stagnant brow hairs were growing. I’d need at least four more hands to count on my fingers how many brow serums I’ve tried during my time as a beauty editor, yet this is the one I recommend without a moment’s hesitation whenever people ask me for a brow-beefing rec. Trust—you won’t be disappointed!

This is one of the most beloved brow-boosting serums on the market, and it receives high-mark reviews from every retailer where it’s sold. Each tube is full of the brand’s signature cocktail of vitamins, antioxidants, and amino acids and will last you a full four months. (Although, according to the brand, you’ll likely start seeing results between the six- and eight-week mark!) 

That said, if your deadline to obtain fuller brows is tighter—like, say, 30 days or under—you might consider this volume-increasing brow serum from Vegamour. It’s vegan, and the natural formula features the brand’s exclusive Polyphytobase Complex, which mingles strategically with other growth-boosting ingredients like biotin, zinc, and active phytomolecules.

The brow-reviewing crowd consistently gives this fan-favorite eyebrow growth serum resounding applause and five-star ratings. Blame it on the ultra-fancy Hexatein Complex and a unique remix of hair-strengthing proteins and growth-inducing peptides, which, legend has it, will produce full, youthful-looking brows in roughly two months. Oh, and we’ve found the newly designed, super-short spoolie applicator especially helpful when trying to navigate the sparser areas of our brows. Talk about precision.

If you’ve ever attempted to shop for the best eyebrow growth serums on Amazon, you likely gave up three minutes later. Not because there’s a shortage of options but quite the opposite! Trying to find the most effective formulas that aren’t made with sketchy ingredients and won’t cause irritation is like trying to find a needle in a haystack. So we’ve streamlined the process for you by finding one of the very best options you can nab on the retailer: this formula from Pronexa. The crowd goes wild for this stuff! Despite the fact that it has over 45,000 ratings, it still maintains a solid four stars. Plus, the powerful blend of botanicals will work their growth and lengthening magic on your lashes if you so feel inclined. 

This high-quality brow serum was devised by brow-shaping genius Joey Healy himself, (as someone who’s been lucky enough to have Healy work on my own arches, I can 100% attest that he’s an absolute dream), so it makes sense that his namesake growth-promoting brainchild would be one of the best serums in the biz. It’s a personal favorite that I always have on hand, and it’s another one I consistently recommend to my friends and family. The everything-but-the-kitchen-sink ingredient list includes everything you could want or imagine: pentapeptides; hyaluronic acid, hydrolyzed wheat protein; vitamins A, B5, C, and E; plus botanicals like white tea, licorice, eyebright, and rose. It’s a splurgier option, but one that makes total sense given its stellar composition. 

With a solid 4.5-star rating and over 25,000 reviews on Amazon, this eyebrow growth serum from Covergirl proves you don’t have to spend a fortune to get your hands on a truly effective formula. If you’re looking for something under the $10 mark, we highly recommend this clear option from the brand, which promises longer, thicker brow hairs in as little as 30 days. Plus, you can kill two birds with one stone by combing it through your lashes for a more fluttery lash line in the same time frame. 

This brow-boosting elixir from Province Apothecary has quickly made a name for itself as one of the most results-driven, ultra-natural solutions in the industry. It’s a top seller at a handful of our favorite retailers like Verishop, Credo, Neiman Marcus, and The Detox Market. It’s clean but mighty (the buzzy ingredients include castor seed oil, argan kernel oil, jojoba oil, coffee, burdock root, and calendula flower), and all you need to do is apply one to two drops to your eyebrows—make sure they’re wet to increase absorption—and massage it all in for 10 to 20 seconds. For the best results, let it all marinate for five to 10 minutes before carrying on with the rest of your routine or plunking your face down onto your pillowcase. 

While French beauty brand Talika might not be as well-known to the masses as some of the other names on our list, this special growth-enhancing brow brew holds a special place in many beauty editors’ hearts. (It’s kind of iconic within our circle.) The applicator is sheer brilliance—a handy doe foot sits at the top of the spoolie like an actual crown—and a concentrated melody of plants, peptides, pigmentation boosters, and protective silk proteins—aka the brand’s Mythical Botanical complex—will begin wielding its transformative scepter of powers in as little as six weeks. 

Antioxidants, amino acids, vitamins… The gang’s all here! Here lies more proof that the very best eyebrow growth serums don’t need to break your budget. E.l.f. Comsetics is one of our all-time-favorite drugstore beauty brands, and this little tube of arch support doesn’t disappoint. The price is even more alluring since this formula tag-teams as a lash serum to boot. 

Okay, so I kind of feeling like I’m cheating with this one since this clear lifting-and-setting gel from Kosas is *technically* more of a makeup product than a traditional brow growth serum, but that’s precisely why I love it. Kosas is always at the forefront of innovation, and the fact that this whimsical little wand lets you have your cake and eat it too makes it a must-have on this list. Yes, it will help lift, shape, and define your existing brow hairs, but the lush ingredients will also stimulate new hair growth in the long-term, too. It’s been one of my favorite beauty launches of 2021 by far.

Yet again, we have another double whammy on our hands! This lash-and-eyebrow growth serum is considered one of the absolute best not only in the clean-and-natural beauty sphere but in the beauty sphere, in general. Organic aloe vera soothes away any sensitivity while organic castor oil—which brims with growth-inducing omega fatty acids—enhances the look and length of your brow and lash hairs over time. Just remember consistency is key with these types of products.
