making the most of my natural hair

I heard John Frieda Brilliant Brunette Simply Sleek straightening balm is a good curl booster. I like it because it makes my hair soft. Try molasses or honey. You can either mix it with conditioner and olive oil for a deep treatment, mix with your conditioner daily, or mix a tiny drop in with your leave-in conditioner. Or you can do a rinse with it by pouring a cup of warm water mixed with about a tablespoon each of conditioner and molasses over my hair and do a very quick rinse with cool water.

i have awful frizzy, big, wavy hair when i let my hair dry naturally so for the past few years i've resorted to straightening it. i hate it cause i know how bad it is for my hair and im wanting to grow it long so over the summer im going to leave it to air-dry. but basically i want to know how to make my frizzy waves more defined. i get the odd ringlet when i leave it but the rest of it is uneven waves so it looks horrible. what products should i use etc? i've tried some 'curl activater' products but they made my hair even worse. please help me
