I tried the no-poo thing briefly. Here's how I did the baking soda. I put some in a little paper bathroom cup and I dribbled just enough water into it to make a paste. Then I rubbed the paste into my scalp. It seemed to cover my whole head!

The no-poo thing didn't work for me in the long run though. I gave it a little over a month and I just felt too gross to continue.

Interesting note: My granny was around when I was trying to no-poo and I mentioned the vinegar rinse to her. She was tickled and said that when she was a little girl her own mother made them always rinse their hair with vinegar when they bathed because she said it would make their hair shiny. So people really did use it before shampoo was invented!
