I had a weird graphic bug when I created my character, and now he has ridiculous red hair. I know there is a console in this game. Is there a command to launch face editor again? Most games have that.
If you get to the Black Emporium (revealed on the world map) there is a Transformation Mirror there that lets you edit your character. I got there around level 4 or 5...pretty early in the game. It gives you unlimited character editing at no cost.
