I've been doing the no-poo for about 9 monthes now, or has it been a year? Well anyway, I love it! If you want the details on the method you can buy a book called Curly Girl which is what started the whole thing. Currently because I have braids extensions, I use shampoo now once every two weeks (while in extensions only) then I go back to no-poo when I am out of braids. On the no poo I have not had a problem with buildup, or itchy scalp. I really love it!
Everyone else gave you some good "how-to's" of the method , so I though I'd give you a testimonial, since I've used it consistanlty for 9 mo's.
