There is no need for concern when making your emo hairstyle, what you feel like doing goes! It's not a normal look so therefore people expect it to be all over the place and to be and over all crazy hair cut. Most emo girls and men guys to the jet black hair for their hair cut and they like the unnatural, uneven look it gives it more spunk. Even though the emo look is becoming more common, it is still an uncommon way for a hair cut. So have fun with it dye it black, chop it up and add some crazy highlights.
