Helmets with hair: How do I make them?

[Karukos]

For some screenshots, I want to have a dawnguard helmet where the ponytail of the character comes out at the back (like on the correct spot) How do I do that? Like how do I bring the hair into the creator and all that stuff.

In CK copy dawnguard helmet, change ID slot to sth different than helmet , do the same for nif. Copy nif and change partitions to same thing.

 

Thats basicaly all, you might need to sculp hair later around the helmet.
