Clipper guards are essential for many barbers. They are the object that control how long or short the clippers will cut your hair. When you order a clip guard, it isn’t the inches, but rather the number of the clip that’s important. The higher the clip number the longer the hair length. Haircut lengths 1 2 3 4 are perfect for buzzcuts. If you wanted to achieve a clean tight look with a varied length on top you would ask for shorter clips on the side so 1 or 1.5 with your desired length on top for instance a 3. Depending upon the texture of your hair, you can have your hair styled “up top” with scissors, a brush (“along the grain” or “against the grain” aka brushed forward or backwards), curls, waves, you name it. It’s a matter of preference and style.
