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.

An Overview On Beard Growth Serums

Beard serums are designed to encourage the growth of hair follicles while keeping beards soft, lush, and manageable. These products often include nourishing, blood-circulating ingredients that condition both hair and skin and help facial hair appear at its best. Most men see results after a few weeks of use.

Some beard serums include minoxidil, which goes by the brand name Rogaine. This is a chemical that falls in the category of vasodilators, and increases blood flow to capillaries in hair follicles. While Rogaine is approved by the Food and Drug Administration for use as a hair-loss treatment, it is not generally recommended for use on facial hair. Of course, people still use it for this purpose.

Other beard serums use ingredients like collagen, caffeine, biotin and other B vitamins, all designed to stimulate hair follicles and strengthen the hairs that grow from them. Beard serums may also feature all-natural ingredients such as a blend of oils, including coconut, grapeseed, jojoba, argan and others, which may address specific problems such as itching and dryness. Still, you’ll want to check the ingredients if you suffer from any allergies.

Beard serums are just one of a number of products you can use to make your facial hair longer and fuller. Other products, such as oils, conditioners, beard growth sprays, shampoos and pills you can take orally, are also available. Some are topical, while others — like pills and drops — work from the inside out. These are less messy, but you should check with a healthcare professional before getting started to be sure they’re right for you.

The Beard Growth Serum Buying Guide

  • Look for beard growth serum products that have money-back guarantees and hold on to the receipts. Not all products work on everyone, so you’ll want to be prepared.
  • If you are concerned about minoxidil, you should know that Rogaine is approved by the FDA and has been clinically proven to regrow hair. It can have an unpleasant smell, though, and results vary by individual.
  • Be sure to completely rinse off the beard serum after you’ve applied it and it has dried.
  • Some beard serums can be applied twice a day, in the morning and before bed.
  • To use beard growth serum, you have to first wash your face and beard well. Then, pat everything dry with a clean towel.
  • Always shake up the serum so the ingredients get thoroughly mixed, then pour the instructed amount into your palms. Massage the serum into your beard using a circular motion in the area that you want to encourage growth. Cover the area evenly and make sure that the patches are coated.
  • You will have to wait about 10 minutes or so (read the label to see how long) until the serum dries. Then, rinse it off with lukewarm water and your regular facial cleanser.
