Wow, can't believe I'm asking this, but if you want to go for the trimmed look, how do you do it? Do you just take haircutting scissors and hack away? Or do you use a special razor that leaves a half inch or so behind? (I know there are special razors men use on their faces that leaves hair behind for the "unshaven" look.) How much do you leave behind if you want the trimmed look? An inch? A half inch? A quarter inch?
