Honestly, the best thing to do would be to cut them off and then deep condition every time you wash your hair. And put a nourishing leave in product on the ends. If your hair is long it won't even be that obvious. You could start with two inches and see how it goes, that might be enough. I decided enough was enough a few months ago and cut two inches off. No one noticed, at least not straight away. And I have been cutting about 2cm off mine every six weeks for a few months now and it's in better condition for it and feels silky - no dry ends. It's necessary to cut to some extent for healthy hair, no biggy really.
