Most people would tend to think that women are the only ones who are interested in celebrity hairstyles; this couldn't be further from the truth. While most men may not want to admit it, they are just as interested, they are just quieter about it.
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.
