If she doesn't need a hood or beanie for warmth, there are lots of cute do-rags available. Some have a pocket to corral long hair; all of them keep hair out of your face and protect hair and scalp from the sun, and come in many colors and patterns. The Scuba-do rag has a ponytail pocket (I used to use one when my hair was long). There's also the Dee-rag (made by an SB-er; I'm sure somebody has the link), and tube shaped do-rags available at sporting goods stores like REI. A bandanna can work too, but cotton takes forever to dry.
Another advantage is, you can always find her under water!
