Might partly just be the way your hair is, many of us do have a mix of curl types. Also might be that you need a haircut to take some of the length/ weight out of the canopy, what products you are using or how you are styling.
Have you read about the Curly Girl method here on NC? Many of us find that our hair gets progressively curlier as it is more hydrated. No sulphate surfactant shampoo, no silicones in conditioner or stylers, no towel turbans, no brush or comb, leave in conditioner, styling products are usually scrunched into soaking wet hair, regular intensive conditioning treatments.
My hair depoufed the first week of conditioner-only washing instead of shampooing, and silicones make my waves and curls go so limp, especially if they build up, so do a clarifying or chelating wash. Check out the stickies on this board and the newbies board, loads of information on CG and techniques for encouraging curl.
