You just have to apply the beard growth serum and then roll vertically, diagonally and horizontally on the areas that your beard is patchy. The great thing about using a roller to apply the serum is that it promotes blood flow to the area that is being treated.

The increased blood flow will be paired with the vitamins and nutrients from the serum to give you extraordinary results in record time.

The derma roller is designed to improve the elasticity and vibrancy of the skin while stimulating hair growth at the same time. Thanks to this, your beard will look better from the very first use.

Even though using a derma roller might sound like a complicated process, this is not the case. It takes less than two minutes to apply the beard thickening serum on your face properly.

Frequently Asked Questions

Do beard growth serums work?

The short answer is yes. If your beard is not looking good, then investing in a high-quality growth and thickening serum is the best thing that you can do. The serums feature special formulas that promote hair growth and revitalize the skin to help the beard grow thicker and faster.

They work, but you should keep in mind that you will not see over-night results. It takes some time.

Does shaving make hair grow thicker?

One of the most common misconceptions about beards is that if you shave with a razor, the hair will grow thicker. Unfortunately, this is not true, and it’s all an illusion caused by seeing the hair slowly growing after getting a clean shave.

When the hair is still short and is growing back, this will make it seem like it appears thicker.

How do you use beard thickening serum?

If you didn’t use a beard thickening serum before and you are worried that it is a complicated process, then you should be pleased to find out that this is not true. You just have to apply it to dry or damp facial hair. The trick is to place a few drops of serum on each hair to make sure that the entire beard is covered.
