I have fine brunette hair about 1-2 inches above my shoulder with just one long layer in it and side swept bangs (not sure you need to know this). I use a round brush everyday with a blow dryer with the diva styling glaze. However, I can't figure out which shampoo/conditioner to choose: advanced volume OR plump and thick. Which one? I like them both, but not sure which is better for my hair situation if I want to add volume but not dry out my hair.
