I'm glad you liked the game, and thank you for your comment and nice words!
The characters' facial hair is not affected by the body hair mods. Also, if you were using a version of the patch that was not compatible with the game, you'd see a warning message both on the title screen and when starting the game, so you're probably fine.
In either case, you can always re-download both the game and nudity patch. Your saves and other progress will carry over.
