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.
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.1We 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.

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.

A combo of vitamins, antioxidants (from botanicals such as ginseng root,1 chamomile flowers, and bearberry leaves), hyaluronic acid, and amino acids work to enhance sparse spots and overall leave brows looking fuller and bolder.

“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

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,4 and peptides5 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.

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.
