i am a hairstylist and i don't really like it when people bring in cartoons and drawings of haircuts. half of the people still are communicating or having realistic expectations of what their hair will do. i think it would be better if you can scan some magazines at a bookstore and find a picture of what you like. it would be a more realistic interpretation of what you want and your stylist will definitely be able to tell you if will work or not. either way, a picture is better than nothing. i personally keep my own portfolio for people who come empty-handed. you can't go wrong with a visual confirmation of what you expect for the outcome of your hair. good luck!
