I can relate to your frustration. The summer has been awful. One thing to note (which might help). The article What's the Scoop on Silicones (the one with the handy chart for what cleansers are needed) does say that cyclomethicone can be removed by co-washing or other gentle surfacants. Coco betaine isn't necessary (I would attach the link but I'm on my phone).
