Is it possible to have frizzy hair that will never be non-frizzy?

Ive tried pretty much everything for my frizzy hair (all hair products yes john frieda, all natural treatments like oliveoil, egg, etc, not straightening or blow drying, etc.). None of these things have worked at all, so please no suggestions of things like these already mentioned (if u have something completely new, go ahead). So i was wondering is it possible to have hair that is literally impossible to defrizz?
