I haven't tried it. I have really thin hair and I'm always battling with split ends and dry hair. I find that Redken's Smooth-down conditioner and anything by Sebastian really works well for my hair, especially this one: link
Split ends are irreversible though.
Call a few salons and ask how much they charge for dusting and haircuts.
I'd probably be more help if I knew what kind of hair you had lol
