A professional grooming would probably be a great start. I've never seen a husky get truly matted though. You need to get a special brush for dogs with an undercoat. It looks like a rake, works like crazy!

Shaving a husky is generally discouraged. The undercoat protects them from heat and cold. They need in the summer too. They also have quite sensitive skin and can sunburn easily if they are shaved too short. I've heard horror stories of huskies who's coat never grew back after they were shaved. THey could no longer tolerate cold the way a husky should be able to.
