I am not opposed to no-poo and find that the Nature's Gate and 365 shampoos seem really drying....my mom tried and raves about Wen so I figured I'd give it a shot. I really love how it makes my hair feel/look and how the frizzy ends are virtually non-existent now. My hair is fine and has become thin (Vit. D deficiency) and I keep it at my shoulders with long layers. Since I bleach part of it (partial highlights pretty heavy) and also use a large-barreled curling iron or straightening iron several times a week, it's prone to being dry and frizzy.
So my only "problem" with Wen is that my hair looks incredibly greasy within about 16 hours of using it. This isn't too much of an issue if I use it in the AM but I really prefer most days to wash at night so I can straighten it the next day without having to blow it dry first. With Wen it's so oily by the next morning when I go to straighten it that it doesn't look clean at all. Well, actually, it looks shiny and bright but is separating in a greasy way...so looks mostly like I am using too much condition and/or product.
