I used to think the 'fade first' rule was gospel until a shop in Atlanta changed my mind
About two years back, I was filling in at a busy spot off Peachtree Street, and the head barber there, a guy named Leo, did every cut by starting with the top. He said it sets the shape and the fade just follows. I watched him do it on maybe 15 guys that day, and the results were just as clean, maybe cleaner. Now I start with the top on about half my clients, especially if they want a lot off the length. It just gives me a better guide. Anyone else work from the top down, or is that still a crazy idea around here?
