How do I get tousled beachy waves?

At night, what I tend to do is put some straightening balm in my hair (even though you want your hair to be wavy, most also protect against frizz) and then either put my hair into high buns, or into braids. Another thing you can do is put curlers in at night but put them in very loosely. This way, in the morning you will get beachy waves! =)
