How Should Your Neckline Be Trimmed?
Skinny neck? Go Square, or Blocked:
Cut straight across the neckline, the square (or blocked) neckline trim helps a thinner neck look thicker. If you already have the neck of a middle linebacker, it’s probably best to skip this one. A downside of the square neckline is that the trimmed areas grow out and can look unruly after a bit. One note: When you start to notice it, that’s a perfect time to come in for a neck trim at your local Supercuts.
Not into the block-y look? Try Rounded:
The rounded neckline is essentially the square with the corners rounded off. This one also helps thinner necks look a bit thicker, but without the sharp edges. Watch out about the grow-out on this one, too. Keep it neat with regular haircuts and neck trims.
Thick neck? Want it more natural? Pick Tapered, or Faded:
Instead of creating a definitive neckline like the square or rounded looks, a tapered (or faded) neckline follows the natural growth of your hair. It’s shortest at the bottom and gets slightly longer as it works its way up. There are two big benefits of the tapered look: As it grows out, it’s less noticeable that it’s getting longer since it follows your natural hairline. And secondly, it can help a thick neck look thinner.
