I think this is very silly, it will just made harder to give U a good result, once U made mistake on it, the hair won't come back, and U cry to the hair stylist, they can just help U to shape it back to normal but it might become shorter as the length U have desire b4........!!! I tried that b4 I join hairstyling, and now I became a hair stylist, I hate that kind of customers........!!! Hair cut is a job that remove hair in a LIMITED area (means hair length), if U made that area smaller, we will get harder to provide U our perfect creations.......!!!^^
