Troll M to Night Elf M Hair problems

[Sholita]

I have the rogues vengeful leather helmet on but the hair goes threw it and it even has a chunk of the hair missing in the back in the middle, il post a picture if it is needed. If someone gives me a little tutorial i'd be very greatful, im not a total noob in model editing. Thanks in advance, il be helping out others as much as I can afterwards.
