8 Eyebrow Growth Serums That Will Transform Sparse Areas (2024)

After years of over-plucking and waxing, we think it's safe to say, thick and full eyebrows aren't just another fleeting trend. Fortunately, even if you were a victim of the early 2000's pencil eyebrow, have experienced a bit of hair thinning or loss due to aging, or naturally always had thinner brows, fuller brows are a look everyone can achieve. To get fuller-looking arches, you could fill in thin brows with an eyebrow pencil, pomade, or wax. Or opt for a long-lasting approach with eyebrow growth serums—products that contain ingredients like biotin, keratin, amino acids, and B vitamins to stimulate hair growth over time.

What to consider when buying an eyebrow serum

Similar to eyelash formulas, eyebrow growth serums are cosmetic products rather than drugs and can't make claims to grow eyebrow hairs, explains Joshua Zeichner, MD, a board-certified dermatologist in New York City. Instead, these formulas work by strengthening and hydrating eyebrow hairs to help prevent breakage and promote an optimal environment for growth. Here, the best eyebrow growth products you can get over-the-counter, according to skincare experts.

The experts:

• Mona Gohara, MD, a board-certified dermatologist
• Jeannel Astarita, a celebrity aesthetician and founder of Just Ageless
• Joshua Zeichner, MD, a board-certified dermatologist in New York City
• Sonia Batra, MD, a board-certified dermatologist and cohost of The Doctors
• Rina M. Allawh, MD, a board-certified dermatologist in Pennsylvania

For only $25, shop this nourishing eyebrow serum that you can use on your eyelashes, too. The formula contains strengthening peptides, biotin, and moisturizing hyaluronic acid to help nourish and promote the look of fuller and healthier brows. Swipe it along the brows nightly to see a difference in just four weeks. The formula is also hypoallergenic and free of fragrance, alcohol, sulfates, prostaglandins, mineral oil, PEG, parabens, and phthalates.

"I personally struggle with an autoimmune condition called alopecia areata, which is a disease where the immune system attacks the hair follicles, leaving patches of bald spots," says Gohara. "I have had this for over 20 years, and my eyebrows were most impacted. I started using this serum in August 2022 and by October, I had significant improvement in the thickness, fullness, color, and density. The blend of biotin and hyaluronic acid provides an optimal growth environment for hair. This stuff really works—it changed my life."

"This serum creates fuller-looking and thicker-looking eyebrows in as little as two months with consistent use," says Astarita. How? The award-winning formula includes a mixture of peptides, biotin, keratin, and moisturizing agents that not only help boost eyebrow density but also add shine and softness.

We're big fans of the Grande Cosmetics eyelash serum, so it's no surprise the eyebrow serum is equally as great. "This serum contains a peptide that promotes healthier lashes, which can lead to enhanced thickness and length," says Zeichner. But don't expect an overnight transformation—it takes up to four months to see the full results of the vitamin-, antioxidant-, and amino acid-rich formula.

"This sulfate-, paraben-, and formaldehyde-free product contains a blend of nutrients and peptides that nourish follicles to restore sparse areas of the brows without causing irritation," says Batra. One particularly happy user even touts the product as "seriously life-changing." It's recommend to use once nightly for up to three months.

If you're experiencing brow thinning due to age, try this serum. "This product contains biotin, which is an important B vitamin, and proteins that help promote healthy hair," says Batra. It also comes with an eyebrow brush to comb the serum evenly through eyebrows for consistent growth. Use it in the morning and evening every day to experience a difference in four to six weeks.

This physician-developed eyebrow conditioner is rich in biotin, peptides, B vitamins, and green tea extract—ingredients collectively shown to condition and help prevent hair breakage, says Allawh. Amazon reviewers agree it really works—more than 3,000 customers give the product a full five stars.

In clinical studies conducted by the brand, users saw a difference in eyebrow growth in four weeks' time. The formula contains provitamin B5 to help condition brow hair, and biotin and cassia alata leaf extract to help promote the look of thicker hairs, and it's free of potential allergens, like parabens, phthalates, sulfates, and fragrance.
