Sounds like your issue might be the products you're using in your hair. Some ingredients build up quicker than others and I personally have never had a conditioner that did a good job of removing buildup from my hair. even so called clarifying conditioners. If your hair doesn't seem to be growing it's probably breaking and the culprit could possibly be lack of moisture. buildup will lead to a lack of moisture. when was the last time you clarified your hair?
