Is there any type of product that can straighten my roots and curl the rest of my hair atthesametime

I've noticed when some people start taking more care of their curls and start using certain products their roots go from puffy to straight. I wanted to if there are any treatments or recommend products that can help straighten my roots?

Kinda depends on what type of hair you have. Most 4 type hair won't do that but 3 and under will. You could smooth them with a good clear curl activator gel of it's managable. That would work for me. 
It seems to me that as your hair gets longer the curl gets more pulled out, and your hair will be the most straight at the roots (where it's carrying the most weight) and more and more curly  as you go down the length.
