Solution: Use the chart on the back or side of the box to see what result you'll achieve with your current color. Keep in mind that if you hair is naturlly blond, you're less likely to wind up with brassiness than a woman with dark hair who tries to go light. Stick to colors within two shades of your natural hair and look for blond shades in the cool category. The exception? If you have warm undertones, in that case a natural shade is the way to go.
