Shampooing every other day always makes my hair look fuller. Cleaning it, separates the fine strands, giving the appearance of more body. As soon as my hair gets oily again, it begins to "pack together' and looks thinner. Shampooing always temporarily reverses this. One major shampoo manufacturer states this exact same thing on its site. Regardless, it's what I've found to be true for my own hair.
I've also found that coal tar shampoos are the best for temporarily giving my hair a fuller appearance. However, I only use them once a week. Denorex is my favorite.
