I've been experimenting with home-based soaps and shampoos for several years.  I've also tried to use household items for cleaning agents whenever and where ever possible.  Baking Soda, Vinegar, Cream of Tartar, Lime Juice, and tons of other things can come in real handy.

For the last year or so, however, I've been researching and trying out the No 'Poo, No Soap thing.  I started with a baking soda/vinegar replacement for the carcinogen-laced, industrial detergent known as Regular Shampoo.  Eventually, however, I started to transition towards using no shampoo at all.

I absolutely love it!  It took a while to transition, but my hair fills healthier than ever.

I've since researched a lot on the web about what is in shampoo and how others approach the no shampoo method.  There is a lot of information out there!

One of the best starting points seems to be: http://beyondshampoo.com.  You can read about the basic and the toxins in shampoo.  Plus, you can post questions.  It seems to be a growing community.
