Epilator. Still gotta get a trimmer to knock down the overgrowth but epilators work wonders for long term hair management. Warning though, it's painful at first. Just do little sections at a time and use plenty of moisturizing lotion afterwards. Might take a couple times to get all the thick hair follicles out but once you do, it'll just be the baby fine hair that grows back and an epilator cleans that up fast and painless.
