Looking for natural ways to fluff up your brows? Full, feathered eyebrows have been all the rage, but for some, achieving those arches pose some difficulty. While some of us have been blessed with thick lashes and brows, others find themselves with sparse eyebrows. And some of us are still recovering from eyebrow trends of the past. For those who lived, and survived, the pencil thin brow era of the 90’s and early 2000’s know this struggle all too well. As much as we wish we could tell our younger selves to “put the tweezers down!” , there are growth serums and gels to get your brows back into shape. 

Our experts searched far and wide for the best eyebrow growth serums proven to provide you with long lasting results. These are the seven best natural eyebrow growth serums for full and healthy arches.

Best Eyebrow Growth Serum Overall:

Maya Chia - Power Fol Eyelash - Eyebrow Treatment

Price: $110

Review: 4.9/5

With so many treatments on the market, it’s hard to know which will actually provide results. That’s why the top treatment for overall growth goes to Maya Chia’s innovative and clinically proven brow and lash serum. Backed by science, Maya Chia’s formula combines a protein-rich Quadruple Peptide Complex with provitamin B5 and chia seed mucilage that help strengthen, hydrate, and define the brow hairs. Plus- it’s natural vegan formulation means you get real results without any questionable toxins or synthetics. 

The dual ended applicator makes coating your lashes and brows easy, with a fine-tip liner for your lash line, and a wand to comb through brows and lashes. For optimal results, start at the root and comb upwards and outwards for an even coat. 

This powerful serum helps fill in sparse areas and strengthen existing brow hairs for thicker, longer, and healthier looking brows. You’ll start to see the results in as soon as 90 days, but brow hair cycles last about 12-15 weeks, so you’ll see optimal results around 6 months into using.

Although pricier than their competitors, Maya Chia packs nearly double the amount of formula into their tubes, so this serum will last you a lot longer, easily justifying the price tag.

Best for Sparse Brows

Fitglow Beauty - Protein Plant Brow Gel

Price: $28

Review: 4.7/5

If sparse areas are a top concern, you need a growth serum with pigment to temporarily fill in your brows, while the formula works longterm to improve thickness. This Fitglow Beauty brow gel comes in 4 pigmented shades to enhance and sculpt your brows- or, opt for a clear gel for a more natural look. This formula uses certified organic ingredients to boost brows to their optimal health.

Using a plant-based fibre lift technology, this gel shapes and fills your brows for a natural medium-strength hold. Packed with lupine plant protein, containing amino acids and glutamine, brows are naturally thickened and protected against breakage. Bamboo, horsetail plant, and rice bran wax are the star ingredients responsible for nourishing and strengthening.

If a brow pencil is part of your everyday makeup routine, this gel is a great topcoat to lock in pigment, and coat brow hairs for a defined and full brow look. 

Best for Thinning Brows:

Kosas - Growpotion Fluffy Lash + Brow Boosting Serum

Price: $48

Review: 4.9/5

If you’re searching for a miracle growth serum for thinning brows and sparse lashes, look no further than Growpotion. It’s clinically proven, and in just 12 weeks 97% of users saw visible improvements in the length and thickness of their lashes and brows. We love that it’s a multi use serum, that’s easy to use, at an accessible price.

Powered by vegan keratin and a trio of peptides, it’s ultra gentle and safe on sensitive skin. Boasting a hypoallergenic and ophthalmologist-tested formula, it also contains vitamins and hyaluronic acid for a healthy and hydrated sheen.

This is a serum that shouldn’t be combined with makeup, and applied only over clean brow and lash lines. We recommend using it as a nightly treatment, and to use small amounts. A thin layer is all you need to coax your brows into thick and full growth.

Best for Brow Health:

Ere Perez - Argan Brow Hero 

Price: $28.50

Review: 4.7/5

There’s no secret- healthy hair is the key to growing longer, thicker brows. Whether you’re dealing with damaged brows or in need of regrowth from the root, this argan oil infused brow gel is the answer for brow health maintenance. 

Castor seed and argan oil are rich in omega fatty acids, antioxidants, and minerals that support thick and healthy hair growth, all while balancing and maintaining the surrounding skin surface.  Although this gel only comes in one shade, it’s lightly pigmented and works for most hair colours.

Use this tinted gel overtop a pencil, or solo to shape brows into place- if you have sparse areas, we recommend shaping existing hairs to cover any gaps. The vegan fibres in the formula adhere to each individual hair to fluff them into a place for long lasting wear. It’s even sweat-proof and water resistant! 

Best for Bolder Brows:

Kosas - Air Brow Tinted Volumizing Treatment Gel 

Price: $24

Review: 4.8/5

If you haven’t already seen this gel work its magic on TikTok, let’s get you up to speed- this impressive gel has won Allure, Byrdie, and Shape awards, and has clinically proven results. Customers, celebrities, and beauty editors alike love that this lightweight gel is chocked full of conditioning actives that effortlessly tint and gel brows into place.

Although listed as a gel, this formula has a mousse-like texture that provides the perfect amount of tint and hold, without hardening or leaving behind a sticky residue. Air Brow comes in 10 shades, and even includes shades of gray for age inclusivity, so you’ll have no issues finding the perfect shade. It blends castor oil, provitamin B5, biotinoyl tripeptide-1, and plant based microfibers- which together instantly create a thicker, bolder brow, with long lasting health benefits. In fact,  97% of users saw fuller brows instantly! If you need a quick-fix that will also improve hair health over time, Air Brow is for you!

Best Lash and Brow Serum:

Plume - Lash & Brow Enhancing Serum 

Price: $95

Review: 4.8/5

As we recount the best of brows, let’s not entirely forget about lashes. Looking for a 2-in-1 solution to simplify your daily routine? Try Plume’s Lash & Brow Enhancing Serum.

The fine tipped brush is ideal for lining the lash line, and swiping over the brows. Once the serum is fully dry and absorbed, you can apply makeup directly overtop without interfering with the efficacy of the serum. 

This brow enhancer is formulated with nine botanical actives that strengthen and hydrate hair from the root, including soothing aloe vera, hydrating vitamin E, and quinine-rich hickory bark. It remains a bestseller and top rated product, with customers most impressed by the improvement in overall length and thickness. 

Best Eyebrow Growth Serum with Essential Oil:

La bouche rouge, Paris - Eyebrow Serum Gel 

Price: $45

Review: 4.7/5

Taming your brows can be tiresome, but this medium-hold serum is a great way to keep your brows in place while promoting healthy hair growth. This unique brow formulation from La bouche rouge, Paris is packed with pistachio oil, a keratin-rich strengthening agent that promotes healthy hair growth, and Japanese green caviar extract, a protective nutrient-rich algae. Together, these star ingredients help set brows into shape and keep hairs smooth and healthy. 

We love that this gel is packaged in a luxe glass tube and contains no microplastics. If you’re looking for a daily brow gel with high quality ingredients at a budget-friendly price point, look no further.  

Does eyebrow serum actually make eyebrows grow?

Eyebrow serums do work, but don’t expect overnight results. Using quality ingredients, natural brow serums promote growth by strengthening and conditioning hairs to prevent damage and breakage. Growth serums are great for treating existing hairs, but they won’t do a whole lot for entirely new hair growth. Instead, brow serums strengthen existing hairs to reduce the chances of fall-out, and help shape and/or tint brows into place for the appearance of fuller brows. 

Applying brow and lash serums lengthen the life cycle of hairs, which in turn lengthen hairs. Don’t expect any immediate miracles, as most brow serums take 12 weeks to see results. Opt for products with natural ingredients as synthetics and chemicals may advertise faster results, but will only harm your hair in the long run. Hair growth is a process- be patient and stick with it!
