Hello Meeko!
Have you found a groomer to take her to? or sometimes you can find mobile groomers who will come to you. I'm mobile, but I also have a room at home for grooming some cats, coz some are better behaved away from their own home!! You might also find that he tolerates it better with someone else doing it - they are sooo good at playing up their owners!
Hopefully the groomer will comb out all the loose dead hairs, which will make it easier to manage, but you might want to think about a regular appointment, every few months or so, to keep on top of it.
