Product to enhance waves?

Hi, I`m wondering if anyone can help me ... I`m looking for a product to use that will enhance and hold more wave in my wavy hair. I have thick hair that is about 3-4 inches long on the top and tapers on the sides and back down to about 1 inch. I`m wondering if anyone has used a product, or knows of a product that would work to "scrunch" into my hair (or any other styling technique - time to style is NOT a real big concern). I`d like to get as much wave, or possibly curl out of my style as I can. So any input regarding cut would be appreciated as well, particularly if you have tried a combo of cut and product that really has worked well to this end.

THANK YOU!
