Note: Thanks to Diana for this!

01. It's okay if you have day old hair but it's always good to wash your hair! If you wash your hair, blow dry or air dry it--it depends on how much time you have.

02. Comb out your hair and while you are, heat up the curling iron. If you want, apply heat protection spray. Make sure you have a side parting.

03. Once your curling iron is heated, curl 2 or 3 inches of your hair around your head. To give it that wavy, beachy look, run your fingers through your hair so everything looks loose.

04. Take a piece of your hair on both sides, and meet them together on the back--tie with an elastic band.

05. Apply some hairspray, but what I would always do is to add some mousse all around so I get extra volume and I don't have to mess with the hairspray stuff. Plus, it makes your hair look soft and smooth, so it's definitely recommended.
