When it comes to keeping a tidy beard, most of our attention goes to the most visible parts—our cheeks, chin, and mustache—but it’s important to give your beard neckline just as much regard. “Keeping your beard clean around the neck not only provides good symmetry for your face, but it also extends the length of your haircut by keeping the focus on clean lines,” says barber Jason Biggs.

Biggs notes that a well-groomed neckline works for all types of beard styles and shapes, and the benefits go well beyond just looks. For guys with a fuller beard, a trim neckline helps maintain hygiene and removes split ends from the bottom portion of the beard. At the same time, for guys with a shorter beard that lies closer to the face, a clean beard neckline helps lend definition to the jawline and provides a cleaner surface for more advanced skincare– such as masks and exfoliants–to penetrate.

The thing is, getting the perfect trimmed beard neckline isn’t always an easy fit. It’s all about finding exactly where the line should go so that it’s neither too short nor too long, then being able to maintain the look at home. Luckily, Biggs and celebrity groomer Tasha Reiko Brown are willing to walk us through the ins and outs of the process. Keep reading for their expert tips.

Where Should My Beard Neckline Be?

"You can find your beard neckline by tilting your head downwards," says Reiko Brown. "The crease where your neck meets the underside of your jaw is a perfect reference point. Use your fingers. Tilt your head forward and side to side and find the crease where your neck and underside of your jawline meet. You’ll be able to feel it. That’s how far down your beard should extend."

Finding your beard neckline is just the first step of perfect grooming. Your face shape combined with the length and thickness of your beard are going to play a role in the way you trim it, too.

Does Face Shape Impact How You Should Trim Your Beard Neckline?

There are two things to consider when determining the optimal placement of your beard neckline: beard size and face shape. "Face shape absolutely affects the way you trim your beard," says Reiko Brown. "If your face is round, fading your beard close to the skin and leaving it longer towards the chin can add length. For a thin face, leaving more bulk in the beard can subtly give your face more shape. Long faces should opt for a wider shape of facial hair to cut the length. Beard shape can subtly help give you a desirable face shape in a corrective manner."

  • Large beard/Round face: For guys with a voluminous beard and a face shape that’s closer to round, Biggs recommends the neckline be placed lower on the neck to help create a sharper jawline and provide maximum fullness to the beard. Reiko Brown recommends leaving the beard longer towards the chin to lengthen the face.
  • Large beard/Square face: If your beard is large and your face is more square-shaped (as in very angular jaws and cheekbones), consider cutting the neckline slightly higher to accent the sharp jawline. This will draw attention to your natural features. 
  • Short beard/Round face: Guys with a rounder-shaped face tend to have less definition around their jawlines, so Biggs recommends dropping the neckline lower on the neck to create a square shape. This allows for more fullness on the corners of each side.
  • Short beard/Square face: For those with a square face and shorter beard, Biggs advises keeping the neckline on the higher side so that it contours the jawline, thus preserving the naturally bold shape and giving a distinctive silhouette. 

How to Trim Your Beard Neckline

Before you even think of making the cut, Biggs says it’s essential to have the proper tools. Here’s what you’ll need: 

  • An electric trimmer: Rather than a razor, Biggs recommends using an electric trimmer because it will allow for more control and causes less stress to the skin when used frequently. “I would suggest a trimmer that is powerful, yet detailed enough to get into those close spaces and create the necessary tight, sharp lines,” he says.
  • Tweezers: Keep a pair of tweezers on hand to reach any ingrown hairs you may spot as well as to remove any hard-to-get fragments of hair. 

Once you’ve found the proper location for your beard neckline and prepped your tools, it’s time to get trimming. Read on for our experts' step-by-step guide.

Wash Your Face

Start by giving your face and neck a solid wash using your regular cleanser and warm water. This will help to open the pores and soften the hairs, so you can achieve maximum closeness with your shave. Gently towel dry.

Mark Your Face

"Use a white eyeliner pencil to mark your beard neckline before trimming," says Reiko Brown. "Tilt your head in different directions to see if you are going to like your new neckline. Look at it in two different mirrors in the house—bathroom and full length to check your perspective. If unsure, err on the side of caution."

Then, Choose Your Shape

To create a more round shape around the earlobe, gently round the corners of the beard. To maintain a more square shape, inch your way toward the earlobe to create a sharp edge.

Trim

Grab your trimmers and start creating your neckline by following the shape desired. "Cut it down further on the neck and work upwards from there," says Reiko Brown. "When you give yourself a margin of error you eliminate the chance of not liking the end results."

Clean Up

Finally, splash some water onto your neck and beard to clear away any stray hairs and follow with your normal skincare routine. Biggs suggests using a beard balm after you’ve trimmed in order to moisturize the skin and prevent any ingrown hairs. Avoid using products containing alcohol, as it can be harsh on the skin. Finish off with some beard oil to help maintain the general state of your beard and avoid split ends and breakage.

How to Maintain Your Beard Neckline

“I find there is no science to keeping a maintained neckline,” Biggs says, as everyone is different and hair grows back at different rates. “As a general rule, I would say it’s important to maintain a clean neckline at least twice a month to avoid irritation and keep a clean look.”

However, he also cautions against overdoing it, as shaving your beard neckline (or your skin in general) too often can lead to ingrown hairs, irritation, bumps, breakouts, and blemishes. Sure, it’s important to keep a clean look but it’s more important to know your skin type and how much it can take in regard to shaving. And, Biggs reminds us, using a trimmer rather than a razor to tidy up your beard neckline is way less harsh and abrasive to the skin.
