Here is an example of the "undone" ponytail that I've mentioned before. My hair was styled curly (if you want to know how watch the video!) and finished with hairspray. Then, as the day passed it sort of relaxed and "fell" a bit. I grabbed a small clear hairband and loosely grabbed my hair behind my ears. I only wrapped the hairband once. In order to achieve lift at the crown, slowly loosen hair from the hair band until you have reached the desired lift.
The key here is loose. . .you can always pin, or spray, back any other pieces that fall!
