My hair is more sorta that beachy wavy... really on top its straight and underneath its sorta wavy... if I use the hair dryer and a round brush - straight hair without to much work.
Don't fight it... I pull mine up, pony tail, messy buns, twists.. I find using a product for curls help keeps it under control so it doesn't get all flyaway, if I am wearing my hair down going with a beachy wave... another trick is wetting it while in the parks, just wetting my fingers, a couple of times running them through my hair, seem to get things back on track...
