Newbie asks for advice

Hi, everyone. I'm very, very new to this (my last shampoo was on 28th February, 2013) and have been using water only and combing my hair under the running water when I do so, every second or third day. I just found this comm. My hair is naturally wavy/frizzy, (think Hermione Granger hair) and to the bottom of my shoulder blades, and it seems to be responding surprisingly well to the no-poo method so far, much easier to control. However, I'm not thrilled at the oily feel of the hair when I touch it and I'm concerned about potential smell as I hang around smokers a fair bit. I've read things about egg washes and rinses with different types vinegar and baking soda and citrus juices/essential oils and all sorts of things. Does anyone have advice for someone with hair like mine?
