Summarize the following:
Although your shave won’t be as close as a razor shave, it will give you a bald result with less friction. This means you’re less likely to experience irritation and redness post-shave.  If you’d like a little bit of hair left, you can use a 1 guard. You may want to lay down newspapers before you shave your head to collect the excess hair. Normally, you'd shave your hair in the direction of the grain. However, this isn't necessary with clipping because you won't get as close of a shave as with a razor. Additionally, clipping hair with the grain is really difficult, as it's hard to clip the hair if you're moving the clippers over the top of your hair. This is usually level with the middle of your ear. Place your clippers against your skin and move them upwards toward the crown of your head. Make several passes until you reach the area behind your ear. If you feel more comfortable starting on a different section of your head, that’s okay. Do what’s easiest for you. Position the clippers at the top of your forehead. Then, slowly glide them back toward the crown of your head. Stop shaving when you reach the back of your crown. Place your clippers at the nape of your neck. Next, slowly bring the razor up toward your crown. Continue working your way across the back of your hair until you’ve shaved your entire head.

Summary:
Remove the guard from your clippers for the closest possible shave. Clip your hair in the opposite direction of your hair growth. Start at the sides of your head where your sideburns begin. Move from top to bottom when shaving the top of your head. Shave from bottom to top when finishing up the back.
