If you've been craving a true blond color like Carrie Underwood, it's important to know which shades will flatter your skin tone. Look for dyes that include the words warm or golden on the box if you have a warm skin tone. Pick shades described as cool or natural if you have a cool complexion. If you're looking for a big change, blond isn't the way to go. Making the jump from a very dark color to a very light shade requires serious bleaching, which strips away moisture, leaving hair damaged. If you choose overall color (as opposed to highlights), go only one or two shades lighter than your natural shade.
