No matter if your face is graced with thin, sparse arches or the thick, bushy brows of Instagram dreams, chances are an Allure editor probably has a similar brow shape as you. We've spent hours in front of tiny mirrors plucking at our brows (occasionally too much or to say goodbye to our unibrow once and for all) and sitting in the chairs of expert brow shapers to thread, wax, and tint our arches, too. Someone of us can't leave the house without filling in our brows, either. We've also tested basically every brow product on the market. Although we may not have that in common with you, allow us to share our knowledge from all of our experimentation. We rounded up our favorite brow products for filling in, thickening up, and holding our brows in place. Powders, gels, pen, and pencils are all accounted for. You are sure to find your new go-to brow grooming product amongst ours.

Glossier Boy Brow

"I don't care what pencil I use on my brows as long as I finish them off with a light brush of the Glossier Boy Brow in black over my hairs. It adds dimensions back into my brows so the hairs are denser and don't look like brown blocks I've drawn on."

Naturally By Detailed Eyebrow Definer

"This ultra-thin pencil is the perfect width for filling in brows with short, quick strokes that look realistic and last all day long."

Eyeko Brow Gel

"After blending my foundation to airbrushed perfection and drawing on graphic liner, I don't have very much energy left to fill in my brows. The Eyeko Brow Gel is my lazy solution. The tinted gel takes all of five seconds to sweep through arches to keep them in place all day long and fill in any gaps."

Anastasia Beverly Hills Brow Definer

"I prefer the Anastasia Beverly Hills Brow Definer to the Brow Wiz because the shape of the pencil makes it really, really easy for me to get the brow shape I want. Plus, it's so easy to sharpen. I find it easiest to gently run the edges along a piece of paper."

Benefit Gimme Brow+ Volumizing Eyebrow Gel

"I love that I can have a full, bushy brow with just one swipe. This volumizing gel gives my brow the perfect shape that will last all day long."

Kat Von D Brow Struck Dimension Powder

With Kat Von D dropping her first-ever line of brow products, Allure editors were bound to find a favorite in the lineup. We're particularly loving the primer-infused Brow Struck Dimension Powder that has the staying power of the beauty brand's beloved foundation and liner. It features shimmery pigments to ensure brows look as natural as possible and not too matte as some powder brow fillers tend to do.

Iope Eyebrow Auto Pencil

"This is my gold standard brow product. I love that you can build the depth and color with its waxy tip and that it comes with a refill of the product. It's lasted me months of usage, even after using it daily."

Benefit 3D Browtones Instant Color Highlights

"My favorite brow grooming product is the Benefit 3D Browtones Instant Color Highlights. I brush the lightest shade, a gold, through my brows after I fill them in to groom any hairs that are going in weird directions and so they look less harshly dark. It’s the only thing I’ve found that makes brows look more natural when you have a lot of product in them."

Sisley Paris Phyto-Sourcils Design 3-in-1 Eyebrow Pencil

"I love this brow pencil. I use it every day (and never leave home without it!) — it's that good. I particularly like it because it fills in any spare gaps in my blonde brows without looking like I've completely colored them in. The pencil also comes with a built-in highlighter for the inner corners of my eyes, which is a nice added touch."

Stila All Day Waterproof Brow Color

For spottier brows, Allure editors reach for the Stila All Day Waterproof Brow Color. Its felt tip has the ease of a liquid liner, so you can draw on fine, believable hairs in seconds. And once the hair-like lines are set, they won't smudge no matter where your day takes you.

Maybelline New York Brow Precise Fiber Volumizer

"Allure’s resident brow expert, Maribeth Madron, helped create this product. (I call her the brow whisperer, ever since she was able to rescue my eyebrows from years of egregious over-plucking). When devising it, she applied the same fiber technology used in lengthening mascaras to make a brow filler that not only fills in bald spots, but also helps to thicken the existing hairs. As someone with full brows already, I was pleased to see that it filled in the gaps in my brows without making me look like I went wild with a magic marker (most tinted brow products do that), and that the bristles on the brush head combed my brow hairs neatly into place."

Anastasia Brow Wiz

"At first, I thought this ultra-thin retractable pencil was too skinny, but by my second use, I recognized Anastasia Brow Wiz's genius. The tip is so fine that it mimics an actual hair. It’s the perfect shaper and filler, plus the spoolie strikes an effective balance between being soft yet firm. It's changed my brow game from Groucho to great, if I do say so myself." —Michelle Lee, editor in chief

Grande Cosmetics GrandeBrow

"Sure, it has somewhat outdated packaging, but my brow czar, Bob Scott, got both my mom and I addicted. The formulas are perfectly tinted, and they include a serum that grows your brows."

Thrive Causemetics Infinity Waterproof Eyebrow Liner

"The tip is fine (not angled), so that it’s so easy to fill in where you need to and achieve your exact shape without having to clean up. It also has pigments that mimic the color of your brow, so it matches my brow perfectly."

Marc Jacobs Beauty Brow Tamer Grooming Gel

"When talking about brow products, most people think of products to help beef up sparse, light, or wimpy arches. But there are a group of people, myself included, who don’t really need filling in — we need taming. I know, it’s hard to feel bad for people when they have full, beautiful brows that survived years of at-home shaping (or were never plucked at all), but having long, wild brow hairs isn’t always easy (especially if you’re a week or two past when you needed a grooming session). This gel is honestly the best brow tamer I’ve ever used. The clear formula is completely invisible, even after it dries, and because it’s lightweight and flexible, it never flakes or makes your brow hairs feel crusty. And I like the fact that is has a fuzzy, caterpillar-like brush rather than a bristle-covered wand — sometimes the latter can leave unnatural-looking comb marks through your brow hairs."
