The biggest upside of this pricey serum, according to its many fans, is that you begin to see results faster than you do with other formulas. (Think 30 days as opposed to 60 or 90.) It’s formulated with proteins, peptides and fruity extracts to condition and define brows. You’ll also find biotin to protect hairs and allantoin to soothe and calm the area. Ad Operations Associate Vince Gervasi used it for over two months and was pleased with the results. “My eyebrows are already thick and full, but this really helped define those sparse areas. It was easy to use and very simple,” he says. Though he notes, the texture is a bit sticky. “I didn’t really like that it felt sticky on my brows and skin—but maybe it’s because I don’t use any makeup or other products that I’m not used to. However, I will continue to use this since it really helped my eyebrows,” he shares.

The active ingredients are what make this French serum a hit for Assistant Editor Delia Curtis. It’s made with two percent pea peptide to improve hair density, castor oil to encourage growth and panthenol to prevent breakage and strengthen brow hairs. In their rave review, Curtis expresses, “It definitely helps make my brows stronger and helps thicken my existing brow hairs a bit. They feel very smooth and durable to the touch. I noticed that it was really easy to apply and made adding something new into my bedtime routine seamless. Due to the consistency, you have to work the product into your brows and lashes. It drips a little bit, so be careful not to get it into your eyes. If you get it combed in nicely, the dripping doesn't happen.”

This brow enhancing formula is infused with a blend of vitamins, antioxidants and amino acids to help you grow fuller, bolder looking brows in six to eight weeks, with full results in four months. I already have thick, bushy brows, but noticed some sparse areas, so I focused solely on the front and ends of my arches, and surprisingly saw a difference. Thanks to the hyaluronic acid and botanical extract blend found in the formula (ginseng root, chamomile flowers and bearberry leaves), it has a lightweight, non-sticky texture. The thin brush helps glide it nicely through my targeted areas—though I did have mild irritation the first time I used it but it quickly went away after daily use. I will admit it’s a bit pricey, but seeing as it’s enough for four months, I would say it’s worth the splurge (or at least getting the smaller version if you’re going to focus on specific areas like I did).

The boosting serum strives to give you fuller, darker and denser brows over the course of two months. It has biotin, lipids and sodium hyaluronate to help thicken and support healthy hair growth. There’s also panthenol, known to condition and improve hair texture over time. Social Strategist Isabella Mohamed tells me, “I loved it! It was easy to use. I’ve wanted thicker brows but could never find something that works. I love that it comes in a mascara tube, and the quality is amazing. Some may think the price is a little too much, but I saw real change in the tails of my eyebrows, so I think it's great.”

There are a ton of expensive brow serums out there, but nothing quite like this one from Augustinus Bader. “I love all things Augustinus Bader, and this serum is no exception,” says Destinee Scott, associate sales & deals editor at PureWow. “It can be used on eyebrows *and* lashes, and I'm happy to confirm that it works great on both. [When] it comes to eyebrows, when applied regularly (at least once a week), it really helps the hair grow thicker and longer.” The enhancing serum is powered by the brand’s signature blend—TFC8—which features key ingredients like castor oil, hyaluronic acid and biotin. It’s praised for strengthening and nourishing brows, while reducing shedding and preventing brittleness. Scott adds, “I tested the product once a week for four weeks to see if it would make hair grow in areas that typically take longer to fill in (for me, that's from the middle to the end of my brow). Not only did it make hair grow faster than usual, but also thicker than ever before. If you want thicker, fuller brows, this product increases hair density in no time. You may not even need to fill them in with a pencil anymore.”

Swipe this serum along your lash line before applying the remaining product over any sparse spots in your brows to get the most out of each tube. The nourishing formula uses hemp-derived cannabis seed extract, aloe and quinoa to condition every last hair, while supporting healthy follicles for optimal growth. In under two weeks, our Senior Director of SEO and Product Sally Herrod was already seeing a difference in her thin, straight brows. “I was a little skeptical going in as the instructions say, ‘This product is not intended for hair growth or for the treatment of hair loss.’ The directions say 'for fuller brows, draw short, hair-like strokes upwards from the start of your brow to the tail and use morning and night,’ so I followed this to a T to really give it the best shot on my (kind of thin) brows,” she says. “Over the test period my brows did start to look fuller and also darker (surprising, but loved that) so I didn't end up having to fill in my brows as much, which I was looking for so I'll definitely be ordering more. The only thing to call out is the eyebrow brush is very flimsy so it would be much easier to paint on with a thicker brush.”

Some people have credited this serum with bringing back their over-tweezed brows from the ‘90s, y’all. Formulated with a blend of panthenol, proteins and polypeptides, this brush-on serum sets hairs in place while steadily delivering those aforementioned ingredients to your follicles throughout the day. “Years of threading and age have made my eyebrows thinner, making it harder to grow back as fast as they used to,” says Sara Baksh, senior manager of business operations at Gallery Media Group. “The serum was very lightweight, easy to apply and nourishing. My eyebrows did grow quickly and started to fill itself in more. I noticed results in a little over two weeks of using it. I just wish the spoolie was longer to cut down on application time for my long brows.”

Infused with peptides and keratin, the formula promises to improve the appearance of your brows (and lashes) in about 12 weeks. The serum also has pro-vitamin B5 to promote healthy shine and hyaluronic acid to condition. Social Media Graphic Designer Jessica Wong primarily used this boosting serum for any sparse areas in her brows. “It was a quick and easy routine to follow every night, and I loved how it kickstarted hair growth in areas where I hadn’t seen any progress in a while,” she shares. “I didn’t love the residue I woke up with each morning, but the results were worth it, so I’d definitely continue using it.”

PureWow is a big fan of Vegamour’s haircare products, so it’s no surprise that the brow serum is a hit. Key ingredients include red clover, a natural DHT blocker to minimize thinning and hair loss, along with mung bean, which helps strengthen hair follicles and prevent premature shedding. You’ll also find hair-loving zinc and biotin, too. The brand claims you’ll see results in four to eight weeks—though Influencer Marketing Coordinator Jamie Ambos suggests using it way past the eight weeks, as she saw subtle results. “I did really notice a huge difference after three months, but I’d continue to use it in my routine to see again,” she says.
