Remember that hair grows forever, it doesn't stop. If you go out on a limb, drastically change your hairstyle and end up hating it, it can always be changed to something else, another style or color. Talk to your stylist to see if they have any fun celebrity hairstyles for you. You never know, they may have a style that they have been dying to try on you, but never had the opportunity before. Most hairdressers won't try to push a new style on you (nor should they), but if you ask, they love to share their creative side.
When men watch celebrities, with whom are they most interested in? Tom Cruise, Brad Pitt, perhaps David Beckham? Who ever it is that men tend to watch, they too go to their barbers and ask for specific celebrity hairstyles. The difference between men and women is that they don't necessarily tell each other that their hair is styled after a particular celebrity.
