I'm experiencing a glitch where werewolves are automatically assigned one of my CC hairstyles and I can't remove it. I don't want to remove it from my mods, so I'm wondering if there are any cheats or mods to remove someone's hair in-game instead? Kinda like how you can change body part values and such in MCCC, which is essentially CAS-stuff done in live mode. Are there any ways to "take off" hair with cheats or mods?

you might want to check for updates or new mods on community websites like ModTheSims or The Sims Resource. Always ensure that any mods you use are compatible with your game version and come from reliable sources.

Open the package file of the offending hair in Sims4Studio, there will be an option to disable it for random or you can even disable it for werewolves.
