The first rule when getting a buzz cut is learning how to grow out a buzz cut. If you're looking to progress from a buzz cut to something that incorporates a shorter back and sides (which is, basically, like 90 per cent of all men's hairstyles), then it may be worth making regular trips to the barber shop for maintenance trims. Firstly, if you're looking to grow your hair out into a rounder or longer shape such as a mod cut or a wolf cut, then it may be best to hold fire as you will need to grow these parts out at some point.
