I think you might be using too much product. I use use Shea Moisture Restorative as my leave-in, and I definitely don't need to use an additional rinse-out with it because it's so moisturizing. You said you cowashed, used a rinse-out, applied a leave-in, then used two stylers and and once more to SOTC. 3 conditioners and 3 stylers would, at least for my hair, not play well because my hair gets--for lack of a better term--confused and overwhelmed when I use more than just a few products. Plus, that must get expensive when you have to rebuy when you run out!
The cowashing probably cannot remove all of the product, causing the plasticky feeling. I'd recommend cutting out a few products. I would remove the rinse-out, pomade, and the gel, leaving you with just the low poo, cowash, leave-in, and KCCC. My hair gets weighed down easily, so cowashing never worked for me. I only use a low poo, leave-in, and styler right now, and my hair is very happy!
Hope that helps(:
