Olmert
I've tried a fair few shampoos over the years and I currently use Kerastase Capital Force for men. Its good stuff and it helps me a lot and I've got really soft fine silky hair.
Also for texture I use Sea Salt spray on damp hair.
When dried with a hairdryer the difference is amazing!

Try Bed Head for Men Charge Up Thickening Shampoo and Conditioner- it gets great reviews- just bought it 2 weeks ago and Love it

I started using Volumique System about three months ago and my hair loss stopped after 30 days and now after 90 days I am seeing some new growth. It seems to be the best at adding more volume to my hair. and the conditioner is great to. I heard the guy that came up with the Volumique devolped it beccause of his wifes hair loss.
