There's something so tribal about the sisterhood of female friendships. We love to support one another in every way possible, and this extends to the products we use, too. Most women are likely to share the secrets behind their glowing skin or Instagram-ready makeup with their friends, and buy other finds based on peer-to-peer recommendations.
Since we all take time to experiment with different moisturizers, eye shadows, and the like, this common exchange is simply a kind way to pay it forward. And in the same way you'd ask another woman about her lipstick shade, we're all about asking her how she made her eyebrows look so full, too. But if you don't get the chance to do it in person, there's another route we love: online reviews.
Thanks to women who took the time to leave online comments on Sephora, Ulta, and Amazon, we found seven of the best eyebrow serums to try for yourself.
Overall Rating: 4.3 out of 5 stars at Sephora
Ingredients: The amino acid L-proline and a botanical extract blend help create healthy brows, while hyaluronic acid conditions and hydrates.
Rave Review: "This serum is magic. I had extremely sparse eyebrows and was always very insecure when not wearing makeup, but this has given me the confidence—and the eyebrows—I've always dreamed of. I was very hesitant about purchasing this at first because it seemed expensive and there's always the chance that stuff like this will not work. Thankfully, after a couple months of use, it made my eyebrow hairs longer, fuller, and produced growth in my sparse areas. I don't use this every night because there are nights when I just forget, but it's lasted me five months already." — Kaiaihale
Overall Rating: 4 out of 5 stars at Sephora
The Ingredients: This option contains a phyto-medic complex of herb extracts that helps prevent hair loss while stimulating hair growth. It's also free of parabens and phthalates.
Rave Review: "This product has changed my life. I have never waxed my eyebrows before, but I have over plucked in the past. I have been growing my eyebrows out for a few months now to get them to become more full, stopped tweezing completely, tried coconut oil, vitamin E, biotin, and other 'natural hair growth remedies,' but my hair on my eyebrows was not growing. I got this product four weeks ago and I have fallen in love. Within the first two weeks, there was noticeable growth. My strands are longer, fuller, and are finally growing. I have very sensitive skin and I still have had no irritation occur while using this product. Absolutely love it, the only negative is the price. If it gets my brows where I want them to be by the time I am all out of it, then a one-time purchase is all I will need. Would definitely recommend to anyone." — CarolineB1103
Overall Rating: 4.1 out of 5 stars at Sephora
Ingredients: Arginine, which helps spur hair growth, is the lead product in this best seller. It also includes zizyphus jujuba fruit extract to protect and rejuvenate skin.
Rave Review: "I have been using this for eight weeks, and it works! I have thin, short eyelashes and very thin eyebrows naturally. I've been using this serum along with a Lancôme primer. My eyelashes are noticeably longer, and my brows are thicker. Give this serum at least six weeks before you decide if it works." — Micahdoo
Overall Rating: 4.5 out of 5 stars at Ulta
Ingredients: The vitamins biotin and panthenol fortify the appearance of brows, keratin gives them a healthy appearance, and sweet almond extract adds shine.
Rave Review: "I have blonde, thin, and patchy brows. This was a game changer for me! I noticed within about two weeks that my brows are thicker, fuller, and not so patchy. They still have a ways to go, but so far I'm thoroughly impressed!" — Keelyda
Overall Rating: 3.5 out of 5 stars at Amazon
Ingredients: The vitamins A, E, and C help strengthen and protect lashes and brows.
Rave Review: "Nothing else worked for me. It doesn't grow them in overnight, growing hair takes some time. It takes about a year for my eyebrows to start thinning out again. I had almost no eyebrows when I started, and now I have a normal amount. This product is simply amazing." — Stargazer Trading
Overall Review: 4.5 out of 5 stars on Amazon
Ingredients: This organic, vegan product doesn't have color, fragrance, parabens, or phthalates, but it does have amino acids to help boost and retain the growth of lashes and brows.
Rave Review: "I have seen a remarkable difference in my eyebrows (that were super thin) and my eyelashes in about three weeks. I was really surprised by the growth enhancement from a relatively low-priced product, as others sell for $100 plus. I figured for the $30 I would take a chance, and I can't be more satisfied if I tried. I wish I had taken photos to show the difference." — Bellafelice
Overall Review: 4.4 out of 5 stars on Amazon
Ingredients: This hypoallergenic and clinically-tested serum has vitamins, hyaluronic acid, and biotin to grow, protect, and maintain brows and eyelashes.
Rave Review: "My eyebrows and lashes have thinned, due to my age (I'm 61). I have wanted to try lash serums, but have been hesitant, as I have eczema and many products will trigger a flair-up. After reading the ingredients and the reviews of women with similar issues, I decided to give this product a try. I am happy to report that I have not experienced any allergic reaction. The product goes on easily, dries quickly, and makes my lashes and eyebrows feel soft." — Rose Harp Lady
