There is a sort of no-poo following, which is people who don't use shampoo.
Well, I'm one of them - mostly.
I don't use shampoo, but my hairdresser does. That's how I can be honest that I don't use it.
What do I do, then?
When I take my shower, I massage my head as if I were shampooing it. Besides, a good massage is worth a million bucks or so, and my masseuse (that would be me) knows what I like!
I brush my hair several times each day.
Both these activities spread my natural oils through my hair, and make it look shiny and clean.
About every six or seven days, I put a heaping teaspoon of baking soda in an empty ketchup bottle. I take this with me into the shower, and add one to two inches of warm water. I mix this well and sprinkle it into my hair. I don't add it all at once, but I do massage it into my hair. I do this until all my hair has been massaged with it. It gets gritty and oily, but I think that's part of what makes it work. After I've gotten all my hair this way, I rinse it out. My hair feels slick and soft.
My hair is very short, so I guess that someone with more hair would use more baking soda and more water, too.
EVERY FOUR TO SIX WEEKS
When I get my hair cut, my hairdresser shampoos my hair. That's how often that happens.
I mentioned my no-poo methods to someone at work, and she said, "Oh, yeah, that's what you do when you want to get all the 'product' out of your hair." Gee, I didn't know that. Did you?
