Having naturally dark blond hair, I was disappointed to find that the only two shades in the pencil are hazel and dark brown, however I bought the hazel one and it is a perfect match with my eyebrows. You have to be careful not to apply too much, otherwise it looks unnatural. It goes on really nicely and its easy to remove any mistakes.
I recommended to a friend and she bought the dark brown one too and now were never with out it, by far one of the most useful things in my make-up bag!
