I second a swim cap, but understand if you don't want to wear one (I probably wouldn't) I have read that you should get your hair wet and coat it with conditioner/oil before getting into the water. This is supposed to prevent the hair from absorbing as much of the chlorinated water. Then wash it/rinse it asap after.
