How Hair Clippers Change Your Head Shape

Discover how a simple clipper cut can change the look of your head shape before you visit the barber.


Did you know that hair clippers can change how your head looks?

Your skull has its own shape. It might be round, flat in the back, or narrow. Hair sits right on top of your bones like a hat. When a barber runs clippers through your hair, they take away that padding. This trick changes your head shape in the mirror.

The Flat Spots and Bumps

Nobody has a perfectly smooth head. Most people have small bumps or flat spots.

When your hair is medium length, it hides these spots. The hair fills in the dips. But if you use clippers to cut the sides down to the skin, your real skull shape shows.

For example, if you have a wide face, taking the sides short makes your face look thinner. If you have a flat back of the head, cutting it too short can make it look even flatter. A good barber leaves a little bit of hair over the flat parts to balance things out.

Choosing the Right Clipper Guard

Clipper guards have numbers on them. Small numbers cut close. Bigger numbers leave more hair. Here is how they change your look:

Number 1 or 2: This makes the hair very short. Your scalp will show through. It slims down the sides of wide heads, but it shows every bump on your skull. Number 3 or 4: This keeps things neat without showing your skin. It is dark enough to hide small bumps and keep your head looking round. * Fades: A fade starts short at the bottom and gets longer near the top. This builds a brand-new shape that can make a round head look square and strong.

Who Looks Best With Short Clipper Cuts?

Clipper cuts look great on people with round or oval faces. Taking the sides short makes the whole face look longer and leaner.

If you have a very long face, super-short sides might make your chin look even longer. In that case, you want the barber to leave a little more hair on the sides.

Also, think about how often you want a haircut. Short clipper cuts grow out fast. You will need to see your barber every two to three weeks to keep the sharp shape. If you wait a month, the hair puffs out and changes the shape again.

How to Talk to Your Barber

Do not just sit in the chair and say, "Make it short." Tell your barber about your head.

You can say, "The back of my head is flat, so please leave some shape back there." Or tell them, "My face is round, so make the sides slim." A smart barber will look at your bones and use the clippers to give you the best outline.
