We Made Easy To Grow Your Beard

Growing your beard can be hard -- but it doesn’t have to be. Here at Wild Willies we live and breathe beards.


We spend day-in and day-out focusing all of our energy on the art of beard growth. That way, you don’t have to. (And to be honest, you don’t want to. Your time is better spent being that badass that you are.)

Boost Your Beard Growth

Love coffee? Us too. Our Beard Boost Serum uses the power of caffeine to pack a punch and assist beard growth. Caffeine promotes hair growth by targeting a hormone named ATP, which is a form of energy that encourages hair growth.


Our serum also includes biotin, which improves your body’s keratin infrastructure and further contributes energy to help your body’s beard-building capabilities.


Together, the two form a dynamic duo of energy-inducing badassery. But science mumbo jumbo aside, the long and the short of it is that our serum comes in clutch.

The Hard Truth About Beard Growth

There are many factors that can affect beard growth. Some of these factors are genetics, hormones, and even your lifestyle habits. (Spoiler alert: all that boozin’ may hurt your beard game, and smoking cigs is a beard killer.) Lifestyle aside, while some of us were born with a beard for the gods, others of us need to pray to the gods for a beard.


Luckily, our serum can help men on each end of the spectrum and everywhere in between. Wild Willies Beard Boost Serum combines the most effective ingredients in order to give your beard the best shot to grow as long and full as you want it to. So yes, that means that even if you struggle to grow a beard, our serum gives you the best shot at doing so.

Why The Beard Boost Serum Is The Perfect Ally For Your Bearded Lifestyle?

First the caffeine stimulates the hair follicles all the way to the root of each hair. This causes the hair to "come alive" and begin to grow... kinda like fertilizer. Then we add biotin to help strengthen each hair follicle so it grows thicker, healthier and stronger so it won't fall out.


Before you know it, you'll be rockin' that full, head-turning beard you've always dreamed of. But you better get it quick because this stuff is flying off the shelves!

Wholesome Ingredients

We take pride in the quality and effectiveness of our products. We are sure you are going to be enamored with your soft, well-groomed beard. What are you waiting for? Give yourself the best beard care available!

Moisturizes Hair

Our beard butter keeps your hair conditioned, smooth and soft, while also giving it a slight hold. It helps keep follicles moist, promoting growth from the inside out. Use it frequently and see your beard strengthen and your hair growth boost.

Made in the USA

We responsibly source 13 natural ingredients and organic essential oils. Then, we combine them, using our unique recipes.

The Best Beard Boost Serum

It can take time to find the best beard boost serum that works, much less a beard boost serum that works and has ingredients that you can feel good about.


We are proud to say that our serum meets both of these criteria. And better yet, all of Wild Willies’ products were formulated with your beard in mind.


Once you join the Wild Willies family, there’s no going back. Your beard, your confidence -- and hey, maybe your love life -- will thank you for growing the beard you’ve always wanted.


Trust Wild Willies Beard Boost Serum to give you the results you’ve been looking for. We’ve got the goods to help you fuel your beard and look great in more ways than one.

Infused with Biotin and Caffeine, Beard Boost promotes: Fast Growth Strengthen, Hair Follicles, Restores Moisture, Delivers a Deep Softening Treatment

Give Your Facial Hair The TLC It Deserves

Don’t leave your beard hanging. Well, besides the hanging off your face part. When it comes to good tender love and care, your beard needs some too. Sure, your beard could grow without the help of our serum and beard supplements, but what fun would that be? Growth would be slower, less impressive, and let’s face it: less badass. And don’t we all want a badass beard?


Make dry, crunchy beards a thing of the past! Wild Willies Beard Boost Serum spoils your beard with a deep softening treatment that restores moisture and makes your beard feel as good as it looks. There’s more than meets the eye, though. We don’t stop at a soft, moisturized beard. Our serum also strengthens your hair follicles so your beard not only grows faster, but healthier and thicker as well.

Have Doubts? We Got You

How long does it take to work?


Due to genetics, hair growth results can vary.Some guys see results in just a few weeks while others can take up to 90 days or longer.


If you struggle to grow facial hair, it won't be a magic bullet that helps you suddenly start growing a beard, but usually it provides an excellent boost to maximize growth and fill in patchy spots.


Are there any side effects?


We're not aware of any side effects associated with The Beard Growth Supplement, including conflicts in taking it with daily vitamins or excessive growth in body hair. 


Before taking this or any dietary supplement you should always consult with your doctor to address your individual health and medical needs. Should any negative reactions occur while using the product, please discontinue use and consult with your physician.


What is Biositol AsX Complex?


BioSitol AsX Complex is our proprietary blend of:


Choline bitartrate (a constituent of lecithin, good for its cognitive boosting properties and liver health).


Methylsulfonylmethane (a chemical found in green plants, animals, and humans) helps to alleviate GI upset, musculoskeletal pain, osteoarthritis, allergies; boosts the immune system and fights antimicrobial infection).


Inositol (a carbocyclic sugar that is abundant in brain and other mammalian tissues, good for the storage and metabolism of amino acids).


All which work together to provide the perfect environment for beard growth.


Does Alcohol affects my results?


We recommend avoiding alcohol while using The Beard Growth Supplement as alcohol inhibits absorption of Biotin (the main ingredient in our supplement) and would therefore negatively impact the effectiveness of the product.
