Are you talking about washing hands or hand washing clothes?
If your talking about washing hands, here's what I do. Actually, I think I got this idea from Ruthla some time ago.

I use a natural dishwashing liquid (Trader Joe's or 7th Gen) I fill a foaming soap dispenser with 3/4 water and 1/4 soap. Shake it up. And your good to go. It works very well, does not dry my skin and it's super cheap. Smells good too.
I use to do the same thing w/ Dr. Bronners. It also worked well but I have very hard water and it left a lot of soap scum in and around my sink. It always looked dirty. I'd clean it and a couple hours later it looked dirty. Now I don't have that problem.
