For men, there are a lot of retro hairstyles from the really funky to the really sharp to the old gangster and mobsters of the past days. Retro hairstyles often look great on guys because the change is not as significant as women's styles. Some guys prefer retro hairstyles because they look better with them than many of today's current styles. Some of the best resources for men's retro hair styles include "The Great Gatsby" and "Gattaca" which both provide different styles. The Great Gatsby offers older retro hair styles while Gattaca offers a futuristic twist to it.
