To avoid getting color on your skin, delicately apply a thin layer of petroleum jelly to your hairline with your fingertips. Get as close as possible to your hairline, but be careful not to get any in your hair.

Unclip the section of hair with the most visible grays. You're going to start here. Use the included brush to paint the color mixture along your roots, or wherever you see silver strands. Once you've completely coated your first section, repeat on the rest of your hair, until there's color on all four quarters of your hair.

Set your timer for 10 minutes -- or 15 if you're battling particularly stubborn grays -- and relax (or even pamper yourself) while you wait for Root Touch-Up to work its magic.

Give your hair a good rinse, and apply your conditioner of choice. Now you're ready to blow-dry, style and rock your newly colored mane.

The only thing left to do? Confidently flaunt your lustrous, richly colored strands. Bonus: When people inevitably ask you who your fab colorist is, you can take all the credit.
