Who else recommends it? Health.com and PureWow both picked the Vegamour Eyebrow Volumizing Serum.

Both Friese and Reslan recommend this pick, as does brow expert Azi Sacks. “The formula contains zinc and biotin, both of which are essential for healthy hair follicles,” says Friese, who also lauds it for being vegan and cruelty-free and notes that you can start to see results in as little as 30 days. Reslan agrees, and calls it her, “go-to brow product,” while Sacks notes that results last even after you stop using it.

“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.

Active Ingredients: Amino acid, hyaluronic acid, glycosaminoglycans | Size: 3 milliliters | Dosage: Once daily | Cruelty-Free: Yes | Byrdie Clean: No

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.

Active Ingredients: Biotin, peptides | Size: 3 milliliters | Dosage: Once daily | Cruelty-Free: Yes | Byrdie Clean: Yes

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. Byrdie’s Senior Social Media Manager Kelly Gallagher vouches for this biotin-based formula in particular. 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.

Active Ingredients: Biotin, amino acids, peptides | Size: 6 milliliters | Dosage: Twice daily | Cruelty-Free: Yes | Byrdie Clean: No

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.

Active Ingredients: Argan oil, castor oil, caffeine | Size: 30 milliliters | Dosage: Once daily | Cruelty-Free: Yes | Byrdie Clean: Yes

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. 

Active Ingredients: Biotin, peptides, castor oil | Size: 13.1 milliliters | Dosage: Once daily | Cruelty-Free: Yes | Byrdie Clean: No

Biotin, peptides, and keratin are the stars of the show in this dual-purpose formula. A major hit on Amazon, it consistently pulls in glowing, positive reviews. 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.
