no-poo shampoo

My partner has been using "no-poo" for about 3 months and I joined the crusade against polluting our streams with chemicals, even "organic" ones, a couple of weeks ago.

Baking soda paste applied directly to the scalp. If desired, you can follow with a watered down vinegar solution (1 part vinegar to about 10 parts water). I stopped using the vinegar and will try a touch of lemon, since they're in season. I was also told about using yucca flowers instead of baking soda. Since they're blooming all over the hills right now, I will try it and report back. They smell much nicer than vinegar. So... more to come.
