While barbering can be a rewarding career, it can also be physically and mentally demanding. Long hours of standing, high levels of concentration, and dealing with difficult customers can lead to stress and burnout. Some barbers may quit due to these challenges, or because they want to pursue different career paths.

Here, 0 is no guard attached, so it's the shortest haircut possible. Think of a 0 as a fade/skin, and a number 8 as a light trim to the hair.

For a very short fade, ask for #1 or #2 sized clippers on the back and sides (a #1 is 0.125 in (3.2 mm) long, while a #2 is 0.25 in (6.4 mm) long). If you want to keep your hair a bit longer on the sides and back, ask for a #4 (0.5 in (13 mm) or #5 (0.625 in (15.9 mm)).
