How often are you using the CJ cleansers? Did you try the Suave mousse with the CJ cleansers? I ask because the CJ cleansers (even Daily Fix, the cleansing conditioner) have coco betaine, which is a non-sulfate cleanser that can remove and prevent silicone build up (the Suave coconut co-wash you listed as trying at the time would not be able to do that). If the only issue with the mousse was that the co-wash you used at the time couldn't deal with the silicones, then it might be worth revisiting now that your routine includes gentle products that will prevent silicone buildup.
