10 Eyebrow Growth Serums for Full, Bold Brows

1. Best Eyebrow Serum for Fast Results: VEGAMOUR VegaBROW Volumizing Serum

While VEGAMOUR's eyelash growth serum is what put them on the map, the brand's brow serum is just as wow-worthy. It's also natural, vegan, AND promises visible results in as little as 30 days (for all you impatient skincare lovers out there). However, the full results will be revealed closer to the 4 months mark, so do stick with it. 

The two hero ingredients in this formula are mung bean extract and red clover extract. The former is packed with zinc, biotin, and vitamins A, B, C, B7, and K while the latter contains protective antioxidant properties. If your sparse brows could really use some love, this formula can deliver healthy hair follicles and lush brows in rapid time.

2. Most Nourishing Eyebrow Serum: GRANDEBROW Brow Enhancing Serum

This nourishing eyebrow serum delivers thicker brows in 4 months using a blend of vitamin E, amino acids, hyaluronic acid, and antioxidants. Together this powerful team of ingredients fortifies, hydrates, protects, and conditions. It's also a formula with proven results. In a 16-week study, 100% of people say they saw fuller-looking brows. 

3. Best for Sensitive Skin: REVITALASH COSMETICS Revitabrow Advanced Eyebrow Conditioner

This award-winning brow growth serum delivers iconic arches using its BioPeptin Complex®, a blend of peptides, lipids, biotin, keratin, and green tea extract, and panthenol. While it's proven to strengthen brow hairs and protect against breakage, it's also ophthalmologist-formulated, dermatologist-reviewed, and hypoallergenic. If you have sensitive skin, this formula could be a great pick. 

4. Best for More Defined Brows: NEUBROW Brow Enhancing Serum

This serum features NEUBROW's Dual-Weight Protein Complex® to boost shine, flexibility, and restore the appearance of natural, fuller brows. Peptides, proteins, vitamins, and conditionering ingredients work together to deliver results in as little as 4-6 weeks. This formula also features two other skin-loving ingredients: apple extract to give brows a more defined look and sweet almond protein to create a protective layer, bringing softness and brilliance to your brows. 

5. Best for Super Sparse Brows: RAPIDLASH Rapidbrow Eyebrow Enhancing Serum

This eyebrow enhancing serum uses RAPIDLASH's iconic proprietary complex to create show-stopping brows. It features a unique blend of fortifying proteins, stimulating peptides, and nourishing ingredients like hyaluronic acid, pumpkin seed extract. Together they're designed to show results in about 60 days. It even features a new, shorter applicator that's designed to make it super easy to apply the serum to sparse areas of the brow line.

6. Best Brow and Lash Serum: MILK MAKEUP KUSH Growhouse Lash + Brow Serum

Looking for a growth serum that you can apply to both your brows and your lashes? Try this clean and gentle eyelash conditioner from MILK MAKEUP. It coats brow and lash hairs with nourishing, hydrating ingredients like hemp-derived cannabis seed extract, a peptide blend, aloe, and vitamin B5. Together, the ophthalmologist-approved lash enhancer conditions, strengthens, and boosts thickness for noticeably fuller-looking lashes in about a month. 

7. Best Brow Gel with Growth Benefits: COMPLEX CULTURE FULL OUT Tinted Volumizing Brow Gel in Warm Blonde

If adding another step to your beauty routine isn't an option (we get it), try multitasking by using a tinted brow gel that also features growth-boosting benefits. Not only does this brow gel from COMPLEX CULTURE define, tint, and shape brows, it also treats them with biotin to strengthen and condition with every use. 

After receiving this brow gel in their GlamBag, one Ipster writes, "I absolutely LOVE this brow gel!!! It makes my brows look full and fluffy yet super natural. I wear it every day!"

8. Best Natural Eyebrow Serum: BRIOGEO B. Well Organic + Cold-Pressed 100% Castor Oil

If you like to keep your beauty cabinet as holistic as possible, you might try using castor oil for eyebrow growth in place of a specialized serum. This natural ingredient is high in essential fatty acids and vitamin E, which are known to promote hair growth and repair damaged hair follicles respectively. It's also made up of a number of other vitamins and minerals that benefit hair and skin. Another one of castor oil's star components is ricinoleic acid, an ingredient that has been said to improve blood circulation. More circulation results in more nutrition to your hair follicles, which leads to stronger strands and less breakage. 

9. Best for Everyone: SHISEIDO Full Lash and Eyebrow Serum

This eyebrow serum ticks all the boxes: it's super easy to apply, affordable, and features an innovative formula. We'd expect nothing less from the high-tech, science-focused Japanese beauty brand. In addition to using eyebrow growth-promoting faves in its formula, the serum also uses one unconventional key ingredient to create fuller brows: arginine. This amino acid conditions lash hairs to boost volume and minimize sparse spots in about 4 months. 

10. Best Drugstore Eyebrow Serum: NEUTROGENA Healthy Lash + Brow Enhancer Serum

The trouble with a lot of eyebrow serums is that they often cost a pretty penny. This affordable, ophthalmologist-tested option from NEUTROGENA is a great way to promote growth without breaking the bank. Infused with peptides and biotin, it keeps both lashes and brow hairs conditioned and nourished. It also features a fine-tip applicator which makes it easy to show sparse areas a little extra love.
