I've been shampoo free for three years, now. It's like the parent says. My transition period lasted 4 weeks and I wore a hat the entire time. After that, my hair was the softest it's been in its life. No fuss, no muss. I wash it daily with water, when I shower. I use neither shampoo nor conditioner, just water.

Here's an article[1] by a guy who did it as well. He was linked on boingboing in 2009 and 2011. His site also has several updates, as much as a year later[2]. I think one of the boingboing guys did it too. There are links to the boingboing articles in the first link[1].

On the soap issue, I remember reading a study conducted a while back about the difference in bacteria counts after going to the bathroom. They compared not washing to washing with water to washing with soap and water. There was one particular bacteria that was only effectively eliminated when soap was used. Apparently, it was small enough to hide deep enough in the folds of your skin that water alone couldn't touch it. So, I do wash with soap after going to the bathroom, but I don't use soap on my body when I shower.
