It seems like everyone wants lush, full brows these days—but not everyone is genetically blessed enough to have them. Add to that the fact that you still may be dealing with some sparse spots leftover from that infamous over-tweezing incident of 2002, and scoring said bushy brows can be more challenging than ever. While filling in your arches with pencils and pomades is a good solution, there are now plenty of over-the-counter brow serums that can deliver long-term improvement. “The latest non prescription brow serums are designed to enhance the thickness of the brow hairs you do have and help stimulate growth in areas that are sparse,” explains Gretchen Friese, a trichologist and BosleyMD stylist.
Byrdie Researched & Approved
Our best overall pick is Vegamour Eyebrow Volumizing Serum, an expert-recommended pick that contains both zinc and biotin for results you can see in as little as 30 days. If you're looking for more dramatic results, consider the cult-favorite Grande Cosmetics GrandeBROW Brow Enhancing Serum, which can fill in sparse brows in a couple weeks with twice-daily use.
Note that brow growth serums take time to work—expect to use for anywhere from three to six months of use to see maximum results, according to Friese. That being said, you should start to see at least some improvement in as quickly as a few weeks, given that the growth cycle of your brow hairs is shorter than for the hair on your head, notes hair health and scalp expert Shab Reslan, an advisor for HairClub.
We conducted hours of research on the best eyebrow growth serums, evaluating each formula on active growth ingredients with proven clinical results, like amino acids and biotin.We also took into account how long each serum takes to start working, and of course, what those results actually were. After consulting trichologists and hair growth experts, and considering dozens of formulas, we landed on these top-rated picks.
Ahead, find the best eyebrow growth serums and get ready for A+ arches.

Best Drugstore
CoverGirl Lash Blast Lash & Brow Serum
Works on lashes and brows
Inexpensive
Plastic applicator feels rough
Despite the popularity of the category, this pick remains one of the few brow serums you can get at the drugstore, making it all the more noteworthy. Biotin, peptides, and castor oil help to thicken, strengthen, and add fullness to both lashes and brows; the spoolie brush applicator makes it equally easy to brush onto both. Also nice: It only needs to be used once daily.

“I like that this works quickly, usually within six to eight weeks,” says Friese, who adds that it’s also easy to apply. (Byrdie Email Editor Karli Bendlin is a fan, too, as are plenty of happy Sephora reviewers who rave about the effects.) A combo of vitamins, antioxidants (from botanicals such as ginseng root, chamomile flowers, and bearberry leaves), hyaluronic acid, and amino acids work to enhance sparse spots and overall leave brows looking fuller and bolder. Sacks also likes it, pointing out that it delivers good results and doesn’t dry out the hairs.

Dermatologist-tested and formulated with botanically-derived ingredients, this is choice for those with allergies, sensitivities, or contact lens wearers, according to Friese. Hydrating hyaluronic acid conditions the hairs, while biotin promotes growth. Per the brand, the best results can be seen after 90 days, though they do offer a complete money-back guarantee if you aren’t totally satisfied with the product.

“This contains ingredients that I can stand by, such as peptides, lipids, biotin, and green tea extract, which is rich in panthenol to condition and strengthen brows,” says Friese. She also applauds it for being non-irritating and vegan, as well as free of both parabens and phthalates. The product garners rave reviewers from satisfied users, too, who note that while it takes some time, it does, in fact, work. Although this option is a bit pricier than others on this list, we think the clean formula that will not irritate skin justifies the spend, especially if you have sensitive skin,.

Best With Biotin
neuLash NeuBROW Enhancing Serum
Promises to work quickly
Unique, dual-sided comb applicator
Some reviewers note uneven hair growth
You’ve likely heard of biotin as a superstar ingredient in many oral and topical hair health products; the B vitamin works similarly well for your brows. Alongside biotin, there’s also a potent protein complex full of amino acids, keratin, and peptides to keep your arches strong and healthy, rather than sparse and fragile. FYI, while most brow growth serums are meant to be used once a day, at night, this one should be used morning and night. Although some reviewers note that hair growth was uneven, Byrdie’s Senior Social Media Manager Kelly Gallagher vouches for this biotin-based formula in particular.

Best Natural
Province Apothecary Full Brow Serum
Inexpensive
Natural formula
No included applicator, must apply with fingers
It can be tricky to find a completely clean version of a brow serum, but this one fits the bill. The ingredient list touts a litany of good-for-your hair (and skin) oils; think antioxidant-rich argan and castor oils to help promote healthier, stronger, fuller brows. There’s also caffeine in the mix to help stimulate hair follicles. All you have to do is massage a drop or two into each brow for 20 to 30 seconds.

Users rave about the impressive results for both lashes and brows, lauding both how quickly and how well it works. They also repeatedly point out the texture of the formula, lightweight enough to not feel heavy, yet still thick enough that it doesn’t drip or get messy. FYI, this one does need to be used twice daily for best results.

Reviewers say it can irritate sensitive skin
Broadly speaking, eyebrow growth serums are a pretty pricey product category, making this more affordable option all the more noteworthy. Despite its wallet-friendly price tag, it still contains many of the same effective ingredients as its more expensive counterparts—peptides, panthenol, and plant-based extracts. Brush on the clear formula twice per day, and the brand says you should start to see the effects in as little as 60 days, a claim many happy Amazon reviewers back up, when it comes to an improvement in both brows and lashes; the formula works on both, giving you even more bang for your buck.

Final Verdict
The Vegamour VegaBROW Eyebrow Volumizing Serum is our best overall pick— recommended by all three of the experts we tapped for this story. We love its combo of effective ingredients and appreciate the easy-to-use, doe-foot applicator. and CoverGirl Lash Blast Lash & Brow Serum are two of our favorites, and the latter is also a rare drugstore option. And while as a general rule of thumb, it can take months for eyebrow growth serums to work,
What To Look for in an Eyebrow Growth Serum
