I would maybe look into altering your hair routine, perhaps try CG or a low poo to avoid unnecessary stripping of moisture. Get a great conditioner and leave-in, try to give your hair some of its moisture back. Unfortunately there's really only so much you can do for damaged hair, keep up with your trims or maybe do a Big Chop and start over.
