"It's really easy to do, and it's really cool and fresh," celebrity stylist Harry Josh says. "The key to making the side braid look interesting is to make sure it looks rough and not clean and nerdy. The more organic and loose it is the better it will look."

How to:

1) Gather your hair to the side of your head opposite your natural part (if your hair parts in the center you can go to either side).

2) Do a basic braid down one side and secure with an elastic band.

3) Pull it apart with your fingers and let a few pieces fall out, including long bangs, so that it looks casual and undone.
