It’s not a new theory in fact it’s the same as your wardrobe, dress for success they said but no one made a fuss about your hair. In fact most people neglect to put the same effort into their hair as they do their clothes.
When you are making such an effort to send all the right signals with beautifully fitted clothes, the right colors, the perfect shoes, most up to date look yet by the time you get to your hair it’s almost like you ran out of time & money or at the very least stop bothering to see it through.
When your dressing head to toe remember the stuff on your head! It’s the one thing that you wear daily and can’t quickly change in the washroom of the club. Get hair that suits you, says what you want it to say and that works for you.
