It was very interesting. It's a pretty well known concept that when your hair isn't subjected to all the stuff in shampoos, conditioners and product that your hair will return to it's natural self cleaning state. That's what I was trying, and yeah it worked.
...cool was it a good experience overall?
The only real bad part was the weeks it takes for your hair to go back to creating it's natural levels of oil. Shampoos and things remove oil so hair is typically in a constant state of overdrive trying to replace it, so it got greasy, real greasy - much greasier than anyone in this thread would be able to endure from the sounds of things.
But yeah, it was almost like one day it was back to normal clean looking and feeling hair. I think I went another four, maybe six months before putting anything in it again and it stayed clean.
