Yeah - I've heard of this. My graft was from the inside of my wrist - thankfully I don't have that issue. As Christine said it is a common problem. Hopefully this is the worst of it and you won't have to worry about rads. You could have it lasered but that would likely hurt... I would wait until your tongue is fully healed (say six months) before doing anything about it. One of the guys on here would have to trim it... admittedly KINDA GROSS. But this disease does that to you. It may after a while wear away as you use it more. The guy I was talking about was unable to eat by mouth so it would essentially grow and grow. I think over time that may change and the hairs will wear away. Some else here might be more helpful. Hugs and welcome.
