Even if men don't advertise which celebrity hairstyle they are copying or that they use styling products, they are copying and they do use the products, just like women. Men tend to use products such as mouse and gel, although newer hair products such as putty are beginning to make their way into more and more men's hair styling regimen.
If you have long hair now, it may be fun to try something short and funky, to mix things up some, and have fun with celebrity hairstyles. If you really like the length your hair is now, or it is already short, play with the color. So many fun celebrity hairstyles can be achieved by changing the color. Highlights are another idea that can produce a funky, different style.
