The answer everyone wants is "every four weeks", and for a skin fade that's about right — a fade is sharp for ten days, tidy for another ten, and then it's just short hair.
Skin fade: two to three weeks if you want it looking deliberate.
Scissor cut: four to six weeks. Scissor work grows out into shape rather than out of it, which is exactly why we recommend it to anyone who can't get in often.
Buzz cut: whenever you can feel it. Most of our regulars come every three weeks and are in and out in twenty minutes.
Growing it out: still come. A shape-up every eight weeks is the difference between growing your hair and just having long hair.
