Just as it may not be right to judge a book by it's cover, admittedly, society tends to form first impressions of people based on their outward appearance. Cloth line, shoes, cars we drive, nails, make-up, and the prominent of first impressions -hairdo.
With that said, what does your hair say about your personality? We all know that it is what's on the inside that really defines a person. But your appearance, including your hair are a part of total package for anyone looking forward in their career or in life and should be considered as something you'd improve just like your resume.
