When to Start Trimming Your Beard?

Leave it to grow for four to six weeks before trimming. That gives you enough length to work with and shows you how your beard grows. 

You’ll see which areas grow faster, where the patches are, and what shape looks best on your face.

You can tidy up the neckline if it’s messy.  Focus on regular washing, conditioning, and brushing so the hair stays clean and trained as it grows.

Essential Tools for Beard Trimming

A beard trimmer is your main tool. 

The sharp blades and adjustable length settings are perfect for bringing the beard to your chosen length. 

You can stop your beard from growing unevenly on one side or creeping too far down your neck.

You'll use beard scissors to cut away stray hairs that stick out after using the beard trimmer.

They’re perfect for shaping your moustache or to clip hard-to-reach areas near your lips or jaw where the trimmer misses.

NOTE: Use proper hair scissors only. Any other scissors will shred your hair and cause issues.

Seamless Fine-Tooth Comb

Use a seamless fine-tooth comb to lay the beard flat, so you can see where the length is uneven.

You'll also spot thicker areas that need to be balanced. 

The smooth edges don’t catch or pull, so you’re less likely to cause splits or tears in the hair. 

Always comb through properly before the trim to get a clear outline to follow.

A beard brush helps smooth the hair and guide it into place. Brushing after a trim also spreads oil or balm evenly through the beard. 

You don’t have to use boar bristles, synthetic or plant-based brushes work just as well.

Use a fixed mirror that gives a clear view of your face in natural or white LED light - yellow or low light hides uneven edges and missed patches.

Position a smaller handheld mirror behind you so you can see your jawline and neckline from both sides.

Step-by-Step Beard Trimming Guide

Wash Your Beard Before Trimming

Trim a clean beard, not one that’s greasy or sweaty. Give it a quick wash, towel it down, and let it dry properly before you start. 

Wet beard hair always looks longer, but it shrinks once it dries, which means you could end up taking off more than you meant to.

Trim the Full Beard First to Set Your Length

Use a guard that’s a bit longer than your beard looks. 

If your beard seems like it's about 1.5cm long, try an 18mm guard first, you can always go shorter after the first round.

Trim in the same direction your beard grows. Go over your cheeks, jaw, chin, and neck to even everything out. You’re not shaping yet. You’re just making sure the length looks even all over before you move on to any detail work.

How to Check for Uneven Beard Length

Stand in front of a mirror with strong, even lighting. Tilt your head and look at your beard from different angles. Uneven areas usually have hairs sticking out or look longer than the rest. 

Press your beard flat against your face. If one side feels thicker or looks puffier, that’s where the overall trim wasn’t even. Go back in with your trimmer on the same guard setting and lightly touch up those areas.

How to Trim Your Moustache Without Ruining the Beard

Put a smaller guard on your trimmer or use beard scissors. 

Close your mouth and look straight ahead in the mirror. If any hairs are curling over your upper lip, trim them back.

Just trim the overhang. Don’t cut upwards into the bulk of the moustache or beard. If the hairs at the corner of your mouth stick out, comb them down first, then trim just the tips so they sit neatly.

Best Way to Trim Cheek Line.

Smile slightly and check where your beard stops growing on your cheeks. That’s your natural line. 

Use a detail trimmer or a clean razor to trim any stray hairs above it, but don’t cut into the fuller part of the beard.

Keep the line soft, there's no need for sharp curves unless you want that look.

Trim the Neckline Last

Look straight ahead and tilt your head up a little. Place two fingers above your Adam’s apple, that’s your neckline. 

Use a bare trimmer blade or a detail head to clear everything below that point.

Keep the line curved and natural. Don’t take it too high or your beard might look too thin from the front.

Simple Checks After You Trim

After trimming, rinse off any loose hairs and add a few drops of beard oil to calm the skin and soften the hair. 

Once your beard is shaped, a give it a quick tidy every week or two. The more often you trim it yourself, the easier it gets to see what needs doing next time.
