I tend to think one's curl pattern is what it is regardless of product use or not. What I think is happening is the tendency for the hair to not clump, so the curl pattern is not as obvious without product. This leads to poofiness. IMHO product does not change what you have, but rather aids the hair in clumping so it becomes apparent.
