Number two haircut Although still very short, the popular number two clipper guard is also used for buzz cuts and fades. However, because the hair is a quarter of an inch long the scalp is not exposed in the way that it is with a zero or one cut. This makes it a good cut for guys who have thin hair or who are balding.

A brief description of the basic overall style you are looking for. Any specific details you can give about: The length of hair you want on top, side, back of head. The type of gradient you want to achieve e.g., Fade or Taper.

Basically, the larger the number, the longer your haircut will be. If you walk into a barbershop and ask for a number 6, you will receive a six guard and walk out with 3/4 of an inch of hair left. On the flipside, if you ask for a 1, you will receive a nearly-shaved head.
