Eyebrow Growth Serums

Byrdie / Chloe Jeong

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. You will have to be patient; it can take anywhere from three to six months of use to see maximum results, adds 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.

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

Hairgenics Lavish Lash Eyelash Growth Enhancer
What We Like
  • Good for sensitive skin

  • Inexpensive

What We Don't Like
  • Takes time to work

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

Best With Biotin: neuLash NeuBROW Enhancing Serum

What We Like
  • Promises to work quickly

  • Unique, dual-sided comb applicator

What We Don't Like
  • Expensive

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

Best Natural: Province Apothecary Full Brow Serum

Province Apothecary Full Brow Serum
What We Like
  • Inexpensive

  • Natural formula

What We Don't Like
  • 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.

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

While you can also use this for the hair on your head, it’s not recommended to be used on lashes.

Best Multitasker: Typology Eyebrow & Lash Serum

What We Like
  • Works on lashes and brows

  • Great value

What We Don't Like
  • Doesn’t contain biotin

For those looking for a product that can pull double duty on both brows and lashes, try this multitasker. It’s specially formulated with a combo of plant-based pea peptides plus castor oil and works equally well on lashes and brows. It’s also fragrance-free, vegan, and made with 96% naturally derived ingredients.

Active Ingredients: Pea peptides, castor oil | Size: 15 milliliters | Dosage: Once daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Drugstore: CoverGirl Lash Blast Lash & Brow Serum

What We Like
  • Works on lashes and brows

  • Inexpensive

What We Don't Like
  • 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. 

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

Best on Amazon: Arishine Advanced Eyebrow & Eyelash Growth Serum

What We Like
  • Works on lashes and brows

  • Non-drippy formula

What We Don't Like
  • Takes time to work

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. 

Active Ingredients: Biotin, peptides, keratin | Size: 5 milliliters | Dosage: Twice daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Best Budget: Organys Lash & Brow Booster Serum

Organys Lash & Brow Booster Serum
What We Like
  • Works on lashes and brows

  • Inexpensive

What We Don't Like
  • 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. 

Active Ingredients: Peptides, botanicals | Size: 7.5 milliliters | Dosage: Twice per day for 60 days, then once daily | Cruelty-Free: Yes | Byrdie Clean: Yes

Final Verdict

The Vegamour VegaBROW Eyebrow Volumizing Serum was a top recommendation from all three of the experts we tapped for this story, a winner for a combo of effective ingredients; we also appreciate the easy-to-use, doe-foot applicator.  There are also plenty of options out there that work on both brows and lashes; the Typology Eyebrow & Lash Serum 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, experts and consumers say the Grande Cosmetics GrandeBROW Brow Enhancing Serum tends to work on the faster end of the spectrum.

What To Look for in an Eyebrow Growth Serum

Active Ingredients

There was unanimous agreement among the experts we spoke with that peptides, panthenol, biotin, and fatty acids are some of the best.

Is It Dual-Purpose?

If you’re looking to get more bang for your buck, seek out multi-tasking formulas that can also work on lashes; many do.

  • How do eyebrow growth serums work?

    As long as the one you choose contains the right types of active ingredients (see our previous point), they can work by both helping to promote new growth and help strengthen the existing hairs to prevent natural shedding or breakage, says Sacks. The big caveat? You need to use one regularly (usually either once daily or twice daily, depending on the formula) and be patient in order to see results, as it can take months.

  • Can you use eyelash growth serum on eyebrows?

    Generally speaking, yes, says Sacks, as lash and brow serums do contain many of the same ingredients. (Hence why there are so many products created as two-in-ones.) Plus, if you’re using one that’s dedicated to lashes, you know it’s going to be gentle enough to use on places other than the eye area.
