The men’s classic side part haircut is one of the most common and popular haircuts throughout the history of barbering. This is a conservative hairstyle that can be worn by any age group. It works great with a suit and tie in a professional atmosphere. However, in recent years it has become a trendy haircut that you see a lot in main stream media. Most notably, this hairstyle was worn by Justin Timberlake for his performance at the latest Grammy Awards Show.
