I went the other way. I used the baking soda and vinegar for several months, and then it just started getting longer and longer between using it, I mostly just washed my hair with water. Finally I ended up going without any shampoo completely. I have used shampoo maybe 12 times in the last 5 years. I still "wash" my hair very thoroughly with water, scrubbing and brushing thru it, I just don't add any man-made products to the process. My hair is thick and curly, I think that helps with it not looking or feeling greasy. I don't think it smells, but then, you never smell your own stink .
