How can i make my hair less greasy?

Lately my hair has been really greasy around my roots...I have straight, medium length, somewhat fine hair...i wash it every night (i am aware that sleeping on wet hair makes it more greasy, so i wash it early at night so it has time to dry completely before i go to bed) I use a few different types of shampoo (sometimes i use all of them at once, sometimes by themselves) I use Aveeno Nourish+Volume Shampoo, Herbal Essences Body Envy Shampoo and Herbal Essences Drama Clean shampoo. I also use 2 different conditioners (Pantene Beautiful Lengths Frizz Control Conditioner and Herbal Essences Drama Clean Conditioner) and i dont put it on the top of my head, just the back of my head all the way down to my ends. I rinse my hair very thoroughly with warm water, then after that i put some anti frizz serum on the ends, comb it, and let my hair air dry....Yet Somehow by the end of everyday my hair feels and looks limp and greasy. What should i do?
