need help and assistance with curly hair

I need help, i've got curly hair, but i don't know what products to use, to define my curls and make them more looser and bigger, without the frizziness, and for it to be more moisturized.

can someone help please!!!

Hey, my hair is fairly thin but I have a lot of it.  I use potion 9 by Sebastian when I first take my hair out of the towel then I spray curl booster by fx after the potion 9.  I used to hate my curly hair becasue I didn't know what to do with it but once I found this combo I have learned to love my hair.  The potion 9 is kind of expensive but if you have a Trade Secret store near you (normally in malls) they have it on sale right now because they changed their packaging so the old ones are on sale.  You can find the fx at any grocery or drug store.  You don't need a whole lot of the 9.  I also use thermasilk conditioner on my hair to prevent further frizzing.
