J.L.
I have the same hair - not really curly but definitely not straight. All those that tell you about Curly hair tips/products do not do not have this kind of hair -- curly hair products/tips do not work - you just need a good cut.
I have been using Noel, an owner at Salon Aqua on Devon in Edgebrook(just east of Central, across from the library) and have been really pleased with how my hair looks for the first time in years.
And after many many years of experimenting, I finally found a solution to let my hair air dry and not look completely frizzy/unkept: a smoothing cream mixed with a curl defining gel - I go about 60 / 40. If I want to look polished, I still need to at least partially blow dry, but with this product mix I can at least have "Saturday" hair without looking like I just rolled out of bed.
good luck.
