I'm looking for a product to put in my hair to make it air dry nicer?

Hi, I have blonde naturally wavy hair that is maybe a centimeter above my shoulders (too short of a hair cut) I also have bangs that are about down to my lips. Anyway, i prefer to shower at night instead of the morning because I hate using heat on my hair and when I blowdry my hair it gets way frizzy and uncontrollable. I'm looking for a product that I can put in my hair after my shower at night so that it will dry in the morning better. I would like it to be a little straighter or at least control the frizzy -ness. Because usually one side of my hair would be normal and the toher side would do something wacky like flip out. Drugstore products please :) also specific brands. Thanks!
