People make dying your hair unnatural colors seem like something taboo...
I can look around any room and find mainly brown, blond(e), and black hair dominates the scene. The thing is... Who wants to be just like Fred & Ella over there? Especially when you can have RED, PINK, BLUE, PURPLE, GREEN, ORANGE, or YELLOW and any color in between! It's amazing what a splash of vibrant color can do.
