    TL;DR<\/p>\n

    \n

    Our overall favorite brow serum, neuLash neuBrow Brow Enhancing Serum, supports healthier, stronger brows, and even manages to fill in sparse areas with new growth. We also love Grande Cosmetics GrandeBROW Brow Enhancing Serum, a tinted serum-meets-gel formula that fills in brows immediately while also enhancing long-term growth.<\/p>\n<\/div>\n<\/div>\n

    While creating thicker eyebrows with pencils, pomades, and powders is a good immediate solution, over-the-counter eyebrow growth serums can help boost long-term natural growth\u2014especially formulas with hair-strengthening ingredients like amino acids or biotin. \u201cFor sparse or thinning brows, I recommend using a growth serum as part of your\u00a0nighttime routine to not interfere with makeup application or longevity,\u201d says Dani Kimiko Vincent, a celebrity makeup artist and eyebrow expert.\n<\/p>\n

    Want to know which formulas are worth investing in? We tested 15 eyebrow growth serums once a day for 12 weeks, evaluating the ease of application, consistency, absorption, overall impact on the look and feel of brows, and how quickly they delivered noticeable results. By combining tester feedback with insights from trichologists and brow experts, we landed on this list of the best formulas that deliver fuller-looking brows.\n<\/p>\n

        Active Ingredients: <\/strong>Biotin, amino acids, peptides | Size: <\/strong>0.12 oz | Dosage:<\/strong> Twice daily | Cruelty-Free: <\/strong>Yes\n<\/p>\n

        You\u2019ve likely heard of biotin as a superstar ingredient for hair, skin, and nails. Well, it works wonders on brows, too. Alongside biotin, this formula boasts a potent protein complex full of amino acids, keratin, and peptides to keep your brows strong and healthy rather than sparse and fragile. To call our tester impressed is an understatement; she says this serum gave her the brows she\u2019d always dreamed of. It was easy to apply, comfortable to wear\u2014including underneath her go-to brow gel\u2014and made her brows look shiny and full. After three weeks of consistent use, her brows were stronger, thicker, and more even-looking. The improvement was so significant that she ditched her brow pencil and gel to go au natural.<\/em><\/p>\n

            If you\u2019re seeking a budget-friendly product that still delivers noticeable results, reach for this one. The multitasking formula calls on castor oil, ginseng, and camellia sinensis leaf (aka green tea) extract to boost lash and brow growth with twice-daily use. According to our tester, the serum works quickly; after only one week, she began to notice more fullness in her brows and eyelashes. Although there wasn\u2019t a noteworthy improvement in strength, her brows looked shinier and had a more even, filled-in appearance than before.\n<\/p>\n

                If you went a little wild with the tweezers a few years ago and are now dealing with sparse patches that refuse to grow back, this is the serum for you. Enriched with biotin to improve hair strength, safflower extract to stimulate growth, and hyaluronic acid to moisturize, this formula helps revive follicles and reduce shedding, leaving brows and lashes noticeably thicker and healthier. It\u2019s not the fastest-acting formula; our tester said it took at least two months of diligent twice-daily application, but when the results kicked in, they blew her away. After 12 weeks, her brow prominence increased by 25%, according to her estimations. Even stubbornly patchy areas like the inner and outer edges of her brows filled in significantly. The only downside is that the applicator can get messy, resulting in wasted serum, which isn\u2019t ideal at this higher-end price point.\n<\/p>\n

                    Wouldn\u2019t be caught dead with a bare brow? Try this serum-meets-gel formula from Grande Cosmetics, which comes in three tints to suit light, medium, and dark hair. Applied once daily, it coats brows with fine fibers, creating a fuller appearance instantly. Meanwhile, moisturizing castor oil and B-vitamin-rich beetroot extract boost the hair\u2019s health, encouraging natural growth. Our tester appreciated how well-groomed her brows looked after a light application (too much product and they became clumpy). With consistent use, she noticed her brows were stronger, less prone to falling out, and had a much fuller appearance overall.\n<\/p>\n

                        Strong, full brows and long, fluttery eyelashes are a dream combo\u2014this multitasking formula is designed to achieve both. It\u2019s made with a powerhouse blend of peptides and keratin to fortify the hair and provitamin B5 for smoothness and shine. Our tester loved the slender doe foot tip, which made precision application really easy, and the serum’s texture, which was so lightweight that it was barely noticeable. With a month of consistent use, her brows felt stronger and were less prone to falling out. They also appeared longer, which helped disguise patchy areas and gave the impression of a fuller brow.\n<\/p>\n

                            Results seem to plateau after two months of use<\/p>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n

                            Active Ingredients: <\/strong>Peptides, hemp seed, aloe, B5, and quinoa | Size: <\/strong>0.12 oz | Dosage:<\/strong> Twice daily | Cruelty-Free: <\/strong>Yes\n<\/p>\n

                            If you prefer to use natural products in your beauty regimen, you\u2019ll appreciate that this serum contains 90% natural ingredients. Specifically, it uses peptides to help strengthen brows and hemp seed extract, aloe, B5, and quinoa to hydrate them. Our tester loved how conditioning and pampering this formula was. She applied it like a clear brow gel and let it dry for a couple of minutes before adding her usual eyebrow pencil over the top. With time, she noticed her brows required less and less pencil\u2014they were looking full and filled in thanks to the serum. The results did seem to plateau after a couple of months, which is natural, given that brows have a natural growth and shedding cycle like the rest of our hair.\n<\/p>\n

                            Samantha, tester:<\/strong> \u201cI feel as if the product made my brows fuller, for sure. I have some patchiness toward the ends of my brows, and I noticed this area took less time and effort to fill in, as well. The change to my brows was subtle, but there was a change nonetheless.\u201d\n<\/p>\n<\/div>\n

                                The Olaplex bond-building formula you know and love has been reimagined for brows! The multi-peptide treatment targets brittle, dry hairs and leaves them stronger, softer, and more supple. It even claims to reduce new grays, giving brows a more youthful appearance. Our tester loved how quick and easy it was to apply the product using the doe foot applicator, making it a fabulous choice for those skeptical about adding this new step into their regular beauty routine. It dried quickly and layered well under makeup, holding her brows in place throughout the day. She loved how shiny and nourished her brows looked, and the long-term results were equally impressive\u2014the treatment noticeably gave her thicker, denser brows by the end of the testing period.\n<\/p>\n

Our tester loved the spoolie brush on this pick, which gives an even distribution of product and doubles as a brow styling tool. The formula also excels; it\u2019s packed with a laundry list of powerful strengthening actives, including our old friends biotin, keratin, and peptides. Plus, hydrating vitamin B5 and sweet almond oil for a touch of healthy-looking shine. Our tester says it absorbed in less than a minute and left her brows feeling moisturized but never oily. With a couple of weeks of use, she noticed her eyebrows seemed stronger, and it even helped fill the inner edges of her brows, which tend to be a little sparse.\n<\/p>\n

                                        If you\u2019re planning to use your brow serum in the morning before applying makeup, then you\u2019ll need a fast-absorbing, quick-drying formula. This one quickly soaks into skin and brows, according to our tester, and it doesn\u2019t leave a crunchy residue behind\u2014just a lingering softness and shine.\u00a0The formula\u2019s star ingredient is arginine, an essential amino acid that promotes hair growth. Our tester didn\u2019t notice much improvement in terms of growth and strength, but her brows definitely looked healthier than before she began the treatment.\n<\/p>\n

Enriched with multiple peptides, the formula actively strengthens brittle hairs, and our tester noticed his brows grew much thicker and fuller within a couple of weeks. He experienced less shedding and even saw new growth on the inner corner of his brow, where it meets his nose. His only complaint was that the applicator tip didn\u2019t hold much product, so he had to re-dip it several times during each application.\n<\/p>\n

Formulated with peptides, biotin, and green tea extract to speed up growth, plus amino acids to strengthen and calendula plant to moisturize, it’s like a protein shake for your brows\u2014packed with everything they need to grow stronger, fuller, and healthier. Our tester gave the serum a rave review for its conditioning abilities, noting that her brows felt softer and shinier than ever. While she didn\u2019t notice any big changes to the thickness or length of her brows during the testing period, they looked and felt undeniably healthier thanks to this conditioner.\n<\/p>\n

                                                  \n
                                                • Active Ingredients:<\/strong> There was unanimous agreement among the experts we spoke with that peptides, panthenol, biotin, and fatty acids are some of the best active ingredients to trust on a label. \u201cIf you see the word peptide in the ingredient list (multiple peptides are even better), it\u2019s a good sign you will get results,\u201d explains Vincent. She also notes that if you are not nursing or pregnant, you can use a serum that contains growth factors called prostaglandins. \u201cThere are many names for the synthetic versions of this growth factor, so if there\u2019s a pregnancy caution on the product, that\u2019s a giveaway that it contains growth factors,\u201d she adds.\u00a0<\/li>\n
                                                • Medicated Formulas:<\/strong> If you\u2019re dealing with severely thinning brows, a medicated formula might help. Board-certified dermatologist Dr. Nazanin Saedi, M.D., FAAD, recommends products with minoxidil, which has been proven to be a safe and effective ingredient for hair growth. It\u2019s typically applied to the scalp, but in low concentrations, it can also help with brow regrowth.<\/li>\n
                                                • Dual-Purpose Formula:<\/strong> If you\u2019re looking to get more value out of your growth serums, seek out multitasking formulas that can work on lashes and brows. These tend to have brush applicators that can be easily used along the lash line or applied in strokes to the brows, especially in areas where the hairs are sparse.<\/li>\n<\/ul>\n

                                                  We asked 15 testers to apply a top-rated serum at home once or twice a day for 12 weeks. At the end of the testing period we collected their feedback and cross-referenced them with insights from trichologists, dermatologists, hair growth experts, and brow stylists. Finally, we created this list of the best formulas to deliver full, fluffy, healthy-looking brows.\n<\/p>\n

                                                      As long as the one you choose contains the right types of active ingredients, they can work by both helping to promote new growth and strengthen the existing hairs to prevent natural shedding or breakage, says brow stylist Azi 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.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/li>\n

                                                      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\u2019re using one dedicated to lashes, you know it will be gentle enough to use on places other than the eye area.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/li>\n

                                                      According to Vincent, growth serums can take up to three months for results to fully be seen\u2014but that\u2019s if you\u2019re diligent about applying the product every day and in some cases, twice a day. \u201cKeep it on your nightstand with a mirror and try to commit to nightly application, as the results really do depend on consistent use, she says.\u201d Once you\u2019ve achieved your desired results, Vincent notes you can scale back on usage and apply it every other day for maintenance.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/li>\n
