Volumizing/thickening product

Hey, I'm male and I have short to medium length hair. My hair is naturally quite fine/sleek and I often use product/hairspray on my hair; however, my hair does not take to it and it becomes flat and gunky within a couple of hours.
 
I believe my problem lies within the pre-drying/straightening process. I've already tried a thickening shampoo, and I've already found that it is making my hair more thicker and less sleek/flat; however, I still want something that will allow my hair to naturally have a dry, matte and volumized finish so that when I blow-dry, straighten and then add product to my hair, it will remain styled and textured throughout the day and styling products will take to my hair easily.
 
I was hoping you could suggest some sort of pre-blow drying/straightening product which can be put on the damp hair and allows your hair to have the most naturally textured and volumized finish so that when adding product such as hairspray or wax - it takes really well to the hair, and keeps a strong hold/lift.
 
I've noticed products such as Bed Head's cooky and Bed Head's Superstar and also Bumble and Bumble Thickening Spray and their Surf Spray.. but I cannot decide which is best for me. I want the one which offers the most extreme lift/volume.
