There’s some debate about whether you should leave the hair dry or wet. You can try it both ways to see what works best for you.

Hair cutting can get fairly messy, so to cut back on that mess, try going outside, where it won’t matter as much. Another option is cutting in the garage. If the weather doesn’t permit either of those, stick to an easy-to-clean area, such as the bathroom or kitchen. [2] X Research source

So, for instance, if you want #2 on the sides and #4 on top, start by buzzing your whole head with #4. Where you start is up to you. You can start at the back or move from one side to the other. You can also start at the top if you prefer. Whatever way you choose, try not to skip around so you don’t miss areas.

If you’re cutting your own hair, place your hand on the top of your head. Use it to guide the clippers, so you don’t take the clippers too far up your head. You can start in the back or move around from one side to the other. [10] X Research source

In the back, clean up the edges a bit with the trimmers.

Use a sharp pair of scissors meant for hair cutting. If you’re in a pinch, try a small, sharp pair of embroidery scissors.

Most clippers come with oil to use.
