What is the best color to dye light brown hair?

It really depends on the current color of your hair, and choosing the right color dye can make all of the difference. Start by identifying the shade of your hair. Hair levels are judged on a scale of 1 to 10, with 1 being black and 10 being the lightest blonde. As a reference point, level 5 is considered to be light brown. Examine your current hair color and rate it based on this scale. Then, compare you current hair color to the color on the box to find a color that is within 2 shades of your current hair color. That way you'll make sure your hair color will look more natural. Additionally, light brown hair dyes come in warm and cool tones, and one might work better for you than the other depending on your skin tone. If you have warm skin tone, then a warm-toned light brown dye would probably work best, and if you have a cool skin tone, then a cool-toned light brown is your best bet.
