Do a patch test. Before dyeing, apply color to a hidden chunk of hair behind your ear to get a preview of the results.
Protect your skin. To avoid staining your skin, rub petroleum jelly onto your hairline and ears. And wear gloves!
Apply it right. Aim the applicator at your scalp, work the color in from the roots to the ends, then comb through.
Set a timer. Leave dye on for the full amount of time listed in the instructions. Rinse with lukewarm water.
