I have been having similar issues with some NPCs walking around lately, I just figured it was because at some point I updated the drivers for my graphics card.
Ask someone else to make a toon with the same hairdo. If they have the problem too, it's because of the game/engine/PW. If they don't, check you graphics card and see if it a. needs updating or b. needs a driver rollback.
I think I saw this before where it indeed was a graphic driver issue. If you need help tonight with testing, let me know. Good luck.
It's a bug with some hairstyles. I had it happen to a companion in a module (not the same hair as the one in the pics), but I don't know if the author ever managed to fix it.
