Lining up your beard will help shape it up. You want to make sure your beard neckline is consistent and even, which you can easily do with a Wahl trimmer. This border clean up takes a small effort, and your beard line will thank you.
How to Line Up Your Beard Step-by-Step
Looking in the mirror, hold your head upright. Whatever hair that you see below your chin needs to go.
With your Wahl trimmer, start trimming just above the Adam’s apple. Your Adam's apple is like a natural dividing line between your beard and neck. This can act as your "center."
Work towards the ears to get a straight line. Refer to your center and work from this middle up to the ear. Do the same on the other side, always starting from the center/middle. Don’t go ear to ear. This can lead to an uneven line.
You don't need to make your beard too rounded (unless that is the look you are going for). A slight curve will look great.
