HELP with communicating to a stylist

Be very very specific. In addition to showing the picture, tell them you don't want fringe, layers etc. Think in advance of words that perfectly describe the cut you want and what your hair needs to get there. If it just needs a blunt trim on the ends to get it to look like Jennifer aniston when she had the one length do (I don't know what do she currently has), just ask for a blunt cut trim, no layers. You should always talk to the person who will be cutting your hair before you get in the chair, ask them exactly what they're about to do, and if you feel like they'll take unrequested liberties with your head, tell them you want to think about it and make an appointment for a later date. Then if you don't think they'll do what you want, call and cancel your appointment and try somewhere else. Remember that its your head and you have the right to have the final say, and no one should make you feel uncomfortable, or suggest that you don't really want what you asked for. If they don't like that, go somewhere that respects what you want as their customer.
