Well sure enough, the Lock Actor check was on for the head object. I KNOW I checked before when you or someone else mentioned it. And sure enough the MT works perfectly.

Just to be sure, though. I loaded a new instance of the hair and unchecked the Lock Actor on the Head, and tried a magnet again, still wouldn't move. I just needed to make sure we didn't go through all this due to my own stupidity.

Thanks for all the help from everyone!
