Thank you so much for not allowing vampires to use it.

I must agree, the fact that we have to cure and re-contract vampirism to even change the smallest things such as warpaint and hair is such a hassle, but I guess it's better than we have it for non-vampires than not having it at all.
I am satisfied that filthy bloodsvckers do not have the luxury of undergoing plastic surgery.
I am dis satisfied that I must pay a thousand septims if I want a haircut.
While 1,000 gold does seem a bit steep for something as small as a haircut, I don't really mind. I'm sitting on mountains of gold and there's not much else to spend gold on in this game, sadly. Perhaps they could have charged you gold depending on what you changed. For example, 100 gold for changing hair, 200 gold for changing hair and color, 200 gold for changing war paint, 500 gold for changing appearance, etc, but honestly like I said it doesn't really matter much because there's not much else to spend gold on in this game.
