The best beard growth serums include powerful ingredients like minoxidil, which can penetrate deep into your hair follicles and promote beard growth in patchy areas.
With these facial hair growth serums, it’s possible to fill in a patchy beard and achieve thicker beard density. I’ve tested a variety of these products to see which ones actually stand up to the hype.

Beard Growth Serum Buyer’s Guide
Not all beard growth products are created the same. I’ve discovered that many brands throw in a few essential oils and claim that it can lead “thicker, healthy beard growth.” However, that doesn’t equal a beard growth serum for me.
Take a look at what you should be shopping for when considering how to get a bigger, fuller beard with these growth serums.
What is Beard Growth Serum?
A beard growth serum combines special ingredients like biotin, saw palmetto oil, jojoba oil, or minoxidil to rejuvenate hair follicles for thicker, fuller facial hair growth. Serums are leave-in topical products applied directly to facial hair and are widely available as standalone or in beard growth kits.
Men use hair growth serums to regrow hair on the scalp, but beard growth serums focus on the follicular growth around your jawline, chin, mouth, and cheeks. If you want to fill in patchy facial hair growth, these products may have the right ingredients to help.
Do Beard Growth Serums Work?
While there are some brands out there that make baseless claims, most of the beard growth serums that I’ve tried led to new growth, better beard care, and even wilder results for my hair and skin.
I chose products based on reviews and the experiences of other men who had great results using beard growth serums.
That said, the ingredients in serums differ from beard growth oils and balms, resulting in more potency.
Whereas you may only find chemicals that tingle or essential oils in basic beard oils or balms, you’ll see more direct hair growth ingredients like biotin or minoxidil in beard growth serums. Therefore it’s important to check the ingredients list first.
Minoxidil is the main ingredient in hair growth products like Rogaine.
Does Beard Growth Serum Help Your Skin?
Beard growth serums do have moisturizing properties that can moisturize and even protect your skin from developing dry skin or acne around your beard.
I say most cases because there are two main types of beard growth serums: biotin or minoxidil. Since certain skin types don’t mix well with minoxidil, you should test a bit of the product on a small patch of skin to check.
Some brands use a formula based exclusively for sensitive skin or oily skin. I’ve included a few below in my reviews.
Most Potent Serums: Beard Growth with Minoxidil
The most potent of the growth serums includes a concentrated amount of the chemical minoxidil, which you may recognize as Rogaine. It also combats issues with Dihydrotestosterone (DHT). It has been clinically proven to work for hair growth, according to multiple studies.
According to my research and others on Reddit, the main ingredient in the best beard growth serums is minoxidil. This compound is approved by the FDA for over-the-counter medicine to treat thinning hair and hair loss.
Minoxidil is the main reason why certain beard growth serums stand out for their amazing results. It’s more potent and absorbs into follicles faster, allowing for greater thickness and hair growth, even in patchy beards.
Researchers have found that minoxidil for beards helps with managing the overproduction of sebum, so if you have a particularly oily skin, beard serums would work better than beard growth oils or even hair growth shampoos and conditioners.
Note on Side Effects of Minoxidil Beard Growth Serums
It’s been found that minoxidil beard growth serums would work well to reduce the oil and penetrate your hair follicles. However, others have experienced issues with acne due to irritation caused by this chemical, which is why you should check with your doctor or test out a patch of hair before going all-in.
Most Natural and potent: Beard Growth Serums with Biotin
However, those with dry skin under their beard may want more moisturizing ingredients and zero chemicals in their serum. For this reason, biotin beard growth serums are better for dry skin and beard dandruff problems.
Are these beard growth serums as effective as minoxidil beard growth products? Not always, if you have dry skin, then natural ingredients like biotin and saw palmetto may eliminate underlying causes to your patchy beard.
Here’s what to look for in the right hair growth serum for your beard:
Most Healing for skin: Serums with essential Oils
However, most beard growth serums you’ll find use a combination of multiple essential oils, while also including biotin.
Typically, these serums may also use jojoba oil or saw palmetto oil as a natural ingredient that has been proven for hair growth. This choice means that you’ll heal and moisturize your skin for full beard growth.
Here’s a full list of the beard stimulating vitamins and minerals that you’ll find in most beard growth sprays and serums:
- Saw Palmetto Oil
- Castor Oil
- Jojoba Oil
- Sweet Almond Oil
- Argan Oil
Top 6 Beard Growth Serums – (Reviewed)
Wondering if you’ll ever get thick beard hair? For some, it’s a matter of age and genetics, but these beard growth serums promised results in as little as 30 days.
Some brands even offered a money-back guarantee if you think the product didn’t work at all, which makes it easier to test out new products if you have the time.
Here are the results from my test with beard growth serums:
1. Beard Guyz Beard Serum With Grotein: Best Price For Beard Growth
I heard about the Beard Guyz Beard Serum with Grotein through some online recommendations and found it at an incredibly low price. While it’s just 1 oz, this beard growth serum works immediately.
This serum is very thick and viscous, so you only need a single drop to massage into your skin and beard. It has a pleasant, woodsy scent that isn’t overpowering, and you can tell it immediately starts to coat hair.
- Beard Guyz Beard Serum
- The package weight of the product is: 3.2ounces
One of the best benefits of Beard Guyz’ serum is the softening ingredients, leading to less coarse beard hair that also feels and looks thicker after a few applications.
I definitely suggest picking up a bottle and using for a couple of weeks to see increased hair growth. It may take up to 6 weeks to see further growth, particularly if you have a patchy beard. It’s best to apply the serum directly to patchy growth to see the difference.Check Lowest Price $9.98
2. Wild Willies Beard Growth Serum With Biotin And Caffeine: High Customer Satisfaction
I’ve tested Wild Willies Beard Growth Serum with Biotin before and had great results. In this follow-up test, I wanted to see if the formula has changed at all, as there were some comments about a change to the formula.
Wild Willies infuses their beard growth serum with concentrated biotin, which is known to help with beard growth, but the brand also uses caffeine in their formula. The combination adds strength to your beard hair, leading to fuller growth after just a week of use.

3. Pure Strength 10,000mcg Biotin Liquid Drops: Best Natural Growth Serum
Sometimes I think it’s best to go straight to the source. Enter Pure Strength 10,000 mcg Biotin Liquid Drops. This serum is basically just concentrated biotin in a bottle that you can add to your beard hair to help it grow faster.
The bottle contains at least 60 servings and has a berry flavor, but it can also be used as a topical. Both ways have offered customers significant hair growth on their scalp and face.

6. Amazon Basic Care Minoxidil 5% Topical Solution: Best Minoxidil Growth Serum
Amazon jumped into the beard growing and hair growth market with their Basic Care topical minoxidil treatment that works for hair and beard regrowth. The package contains 12 ounces of product with an activated formula that contains concentrated minoxidil for fast hair growth.
I was skeptical at first, because what does Amazon know about treating hair loss? However, over 3,000+ positive ratings changed my mind, and after using this product, I can see why. It works, and it’s fairly priced unlike many other minoxidil growth serums I’ve tried.
- ACTIVE INGREDIENT: This product features minoxidil 5 percent w/v, the number one dermatologist recommended active ingredient (of U.S. physicians surveyed by an independent market research firm); compare to Men’s Rogaine Extra Strength active ingredient

You can feel your hair follicles buzzing just after a few seconds of applying a little bit of product to your beard patches. I experienced new follicular growth after using the topical serum for about 7 days.
Other customers had similar experiences, but it took up to 30 days for some to see results. I highly recommend this product if you want to try minoxidil for less, as it’s simply a low-cost, concentrated solution.Check Lowest Price $53.81
