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 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. This is why 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.

The vitamins, minerals, and fatty acids in natural beard serums may help your beard grow faster, but for faster results, minoxidil may be the best option.

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:

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 for an incredibly low price. While it’s just 1 oz, this beard growth serum starts working 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.

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.

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.

I found the new serum to be just as good as the old product with a light, nutty fragrance from the sunflower seed oil. It’s definitely a potent beard growth serum that will thicken your hair, and if not, Wild Willies offers a full refund.

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.

[amazon fields=”B07FJQ32BG” value=”description”]

The makers behind Pure Strength Biotin Liquid Drops state that it has a higher rate of absorption, which allows your body to deliver blood flow directly to your hair follicles.

I’m not sure of the science as the company or other agency hasn’t conducted a full study, but it does work for healthy, thick hair growth. I suggest using it every day for 14 days to see a difference.

4. Isner Mile Beard Oil Leave-In Conditioner: Best Serum For Dry Skin

I’ve been hearing about the 4-Pack Isner Mile Beard Oil Leave-In Conditioner Kit. It’s a combination pack of oils containing cedarwood, sage, sweet orange, and sandalwood. All of the scents are amazing, but I wanted to see if it would affect growth like the other serums on this list.

If you have issues with dry skin, these serums will clear it right up within a day or two of use. I noticed my beard hair was thicker and more lustrous after just two uses, and I particularly liked the sandalwood .

[amazon fields=”B07WRFWR4G” value=”description”]

[amazon fields=”B07WRFWR4G” value=”thumb” image_size=”large” image_alt=””]

The formula includes all natural ingredients, so nothing will irritate sensitive skin. While it doesn’t work as fast as other serums on this list, Isner Mile’s beard oils keep your beard looking clean and smelling fresh. Eliminating dry skin may be the change necessary to get a fuller beard.

5. DOVICH Beard Growth Serum With Biotin: Best Newcomer Beard Serum

I like to give new products a chance whenever possible. There are always new beard growth products that have changed the formula, and users swear by their effectiveness in some cases. That’s true of DOVICH Beard Growth Serum with Natural Biotin.

This is an unscented beard growth serum that contains jojoba oil, argan oil, vitis vinifera seed (grape seed oil), and biotin. It has tons of vitamins, including A, E, C, B1, B2, B3, B6, B9, and B12, as well as minerals like iron and zinc.

[amazon fields=”B082MK4874″ value=”description”]

[amazon fields=”B082MK4874″ value=”thumb” image_size=”large” image_alt=””]

This super powerful serum works beautifully, and within days, you should start to see your beard coming in thicker and growing longer. We were skeptical at first, but it’s safe to try due to their 100% money-back guarantee.

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 of the other minoxidil growth serums I’ve tried.

[amazon fields=”B074M6JNML” value=”description”]

[amazon fields=”B074M6JNML” value=”thumb” image_size=”large” image_alt=””]

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 did take 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.
