Just asking? Really? Funny, I don't see the OP's question as naive at all, but rather someone with an agenda wanting to stir the pot since this is the SECOND time she's started a thread on the topic.

But to answer the questions....
1. WEN is NOT Shampoo!
2. When you consider how many products the Cleansing Conditioner replaces, the cost really isn't all that exorbitant - especially when you are able to get on a cleansing schedule of just a few times a week.
3. The "presenter/spokesperson" - aka Chaz Dean, creator of WEN, is not questionable at all. He has a definite philosophy about hair care and a commitment to using quality skincare type ingredients. I may not agree with everything about him, but I do believe he's honest, genuine, and has integrity.
4. Chaz' hair is not greasy. It's very soft and fine. I think the cameras are deceiving because he's got highlights and the combination of his coloring and texture plus the lighting on the set, it's likely to come across in looking greasy when it's not.
5. The models' hair....No one is trying to deceive. When the models' pictures are shown, there is a caption that says "professionally styled". During the WEN shows, the models get their hair pinned up when they're off camera to keep the style in for when they go back on camera. I doubt that they do this when they're on for another vendor. Could a user do that at home if they wanted to? Of course, and many users do something to hold a style while they're sleeping. No one is inferring that someone will use WEN on Day One, go to bed, and wake up with beautifully styled hair and no bedhead/pillowhead.
