From The Manufacturer

Beards are awesome, especially epic ones. Make sure you reach your potential by using Wild Willies Beard Growth Serum. Here’s how it works: 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! Craft a bold looks that’s all your own. Shave less. Beard more. Honest Confession for Those Seeking the Bearded Lifestyle: Now let’s be honest for a second, if you can’t grow facial hair then this isn’t going to work like some magic beans and help you suddenly start to grow a beard. We wish it could work like that, but unfortunately, we can’t change genetics. With that said, if you do struggle to grow facial hair, then it doesn’t mean that this won’t help. Everyone’s genetics are different and this could be the boost you need. So try it out. After all, there’s nothing more frustrating than wanting to grow a nice, thick beard and not being able to. We just wanted to be clear up-front that this may or may not work for you if you struggle to grow facial hair, it’s all up to your genetics. Fuel Your Passion, Fuel Your Beard. Wild Willies is all about celebrating our differences. We believe you should feel free to be yourself & challenge the status quo when it comes to how you decide to live your life and how you express your own style. That’s why we created our Wild Willies brand. We make a full line of the best products to support your personal style, whether they be for tattoos, your skin, or even your beard.
