The proper way to see your hair is akin to the way you would see a fashion accessory. It is meant to express to the outside world what you are all about. If you are a fun, impulsive, risk-taker then your hair should reflect that about you. That being your personality type then your hair should be as ever-changing, risky and fluid as you are.
Play with shape, colour and length if you so desire. Hair does not have to be one colour or length. Go against the grain!
