Poofy and too soft

I've been CG since Dec 06 and because my hair seemed no different I went back to using poo. The main problem seems to be the texture.
I have bobbed length poofy (not dry) texturless thin hair but I know that given the right conditions my hair can produce a mass of curls with the odd ringlet here and there.
After I shampoo, my hair feels thicker and has more texture, but no curl only a poofy frizz. Whatever condish I use seems to make my hair too soft limp and lifeless.
I can't use too many products because it weighs my hair down.
I have been searching the posts to find similar problems to mine to no avail.
Can anyone please advise. :cry:
