A hair style can tell many things about a person's character and personality.  Always take good care of your hair and the way you showcase it, since you never know who might be interviewing you, or worse checking you out!  Also, don't forget that some people, even prospect employers, can go to extremes when it comes to judging a person on a first impression.  Many people have experienced the cruel reality of having been completely and solely missjudged by the way their hair was displayed during an interview or on a first date!!!  Scary isn't it?!
