I am a Wen user and I absolutely love it!!! I will say there is quite a learning curve with using it though. For some of you who have mentioned a greasy feeling or that your hair feels dirty....you just have to find the right combo on how to do it. It was not love at first for me either but I had spent money on this huge bottle and so many people loved it I figured I must be doing something wrong so I kept at it for a few more washes. I would say by about the 4th time or so of using it I had it down. I need to use 3 pumps near my hairline, 3 on both sides of my head, 3 near the crown, and then another 1 or 2 near the nape of my neck. You have to rinse a lot more than what you are used to with reg. shampoos/conditioners. I also use one small pump as a leave-in near my ends. But honestly once you have the routine that works for you down you will love it! My hair has never felt cleaner, been shinier, or might lightweight than it is now. I have been using Wen for a little over a year and just ordered 3 gallons!!! I can never be without it!
