I have the latest issue of Cosmo magazine, and yess Carrie Underwood does have a really nice hair color. I wish I knew what color her hair is naturally, or what color she started out with. I think you should keep trying to go blonde, as long as that is the color you really want and you're willing to put a lot more time into your hair for touch ups, and more visits to the salon. Also, if you're a person who flat irons their hair every week, (not saying you are, but my friend does this and wanted to go blonde so this is just a warning) it may not be best for you to go blonde with all the extra damage. Anyways, if you take good care of your hair, you don't damage it, and you baby it a little bit it should all work out fine. Best of luck.
