Please help, i have oblivion hair/fallout 3 hair/apachi hair as well as zzjay's custom unique hairs installed. IMO zzjay's hairs are the best but i want to enable these hairs onto NPCs.

I currently use mods that add random npcs in towns(something like populated cities) so i want to enable them to have custom modded hair instead of vanilla hairs. Also, even named npc ingames would be nice for them to have their hair changed

Does anyone know how?
