Interesting, makes me want to experiment but I'm not sure how well I could pull it off. Right now I am using TJ's tea tree shampoo and conditioner. I only shampoo every couple of days (every day is just unnecessary and is too much) but by day 3 I notice my hair starting to look greasy. How much does the success of going shampoo-free have to do with the natural texture and oiliness of one's hair? Mine is fairly thick, wavy, and I would say medium texture (not really fine but not coarse either).
