The best benefit about a bob layered haircut is how it looks beautiful both for curly and straight hair. When you have straight hair, you will get the "Egyptian" look with a round sexy hair with bangs and curved edges. With curly and wavy hair, you will get a playful fun young look like Rihanna with her famous short bob hairstyle. It gives you a more carefree and playful look that many guys admire and find attractive.
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.
