I’m currently looking for accurate Kirk/78 hair that is publicly available. If you have any links or suggestions on where I can find it, please feel free to share. Thank you, everyone!
I know this is an old topic but I heard that someone had the hero hair tested and it was said it was yak hair so here is some blond yak hair I found.
