Why Your Shirt Collar Changes How Your Haircut Looks
Learn how the back of your neck hair should match the shirts you wear every day before your next haircut.
When you get a haircut, you usually look at the front. You check your bangs. You check the sides. But the barber spends a lot of time on the back of your head.
There is a secret rule many people do not know: the clothes you wear should decide the cut on the back of your neck. We call this the neckline.
The Three Types of Necklines
Barbers finish the back of your hair in three main ways:
Blocked (Square): The barber shaves a straight line across your neck. It makes your neck look wider. It looks very sharp on day one, but it looks messy fast when hair grows back. Rounded: The barber makes a straight line with curved corners. It looks softer than a square cut. * Tapered (Faded): The hair gets shorter and shorter until it fades into your skin. There is no hard line. It grows out cleanly and lasts the longest.
Why Your Collar Matters
Think about what you wear every day. Do you wear dress shirts with stiff collars and ties? Or do you wear soft t-shirts and hoodies?
If you wear a stiff dress shirt, your collar pushes up against the bottom of your hair. If you have a blocked line, that hard line rubs right on top of the collar. It can look crowded. Sometimes, the shirt collar even pushes the hair up, making it stick out.
For dress shirts, a tapered neckline is usually best. Because the hair fades away before it reaches your shirt, the collar sits flat against your skin. Everything looks clean and neat.
If you wear round-neck t-shirts every day, you have more neck showing. A rounded or tapered cut fits the natural bend of your neck and looks great with simple tees.
Matching Your Neck and Face Shape
Your body shape matters here too.
If you have a wide neck, avoid the blocked cut. That hard, wide line will make your neck look like a thick brick. A tapered cut makes a wide neck look slimmer.
If you have a long, skinny neck, a blocked or rounded line is actually helpful. The line acts like a stop sign. It cuts off the length and makes your neck look stronger.
What to Say to Your Barber
Next time you sit in the chair, tell your barber what you usually wear to school or work.
You can simply say: "I wear a lot of collared shirts, so please taper the back so it grows out clean." Or say: "I want a rounded finish that is easy to take care of."
If you pick a blocked cut, you will need to trim the neck fuzz every week to keep it tidy. If you pick a taper, you can easily wait three to four weeks.
