Coming out of your shell is another way of looking at it. People who have been so used to being treated in a way try to rebel and assert themselves by getting a new look. It is a way of rebelling from the stereotyping that they have been suffering from without being violent. They say that change happens as soon as people see them sporting a different look. What way than to have a new image to change the way people see and look at you and the best thing is that it makes you feel better with a new haircut.
