One product for wavy hair
I have the same hair type. While I can appreciate the surf spray's out there--they are not great for frizz and are very drying to the hair. Since curly hair tends to be on the drier side I like to use a leave-in conditioner for that beachy look--it leaves your hair really soft--not crunchy or dry in texture. I use it on wet hair but you can dilute it with water to revitalize curls and spray in dry hair. The ones I love are Living Proof No Frizz Leave-in Conditioner--it also repels dirt so you can go longer between washes (for the camper in all of us!)
Carol's Daughter also makes a lighter weight version in two scents--Black Vanilla and Tui.
Bumble & bumble makes one too-you can leave it in or you can rinse it out if you just want it to detangle--I like it when I want to wet my hair without starting over.
