Hi elvis ... never used waxworks but I`d assume as it`s a type of pomade [?] your leave-in conditioner would probably be wasted `on top` of it as the hair/s would be coated with an impervious layer..... when I use Brylcreem I just go with that on it`s own.... I find `Enhance`is best used on `clean` moist hair and allowed to dry-in naturally..... my guess is you`d be wasting it if applying on top of products like Waxworks...
