If hair and lip colors are the only concern that you want to revert you can have:
@CHARACTER previews mouthColor Red Matte
@CHARACTER previews hair Straight
and after, have it reverted:
@CHARACTER unpreviews mouthColor Red Matte
@CHARACTER unpreviews hair Straight
I think it can be used for outfits too, but I don’t think the preview command carries over to the next episode though. I could be wrong.
