Barbie, Marilyn Monroe and Jane Mansfield are all fashion icons known for their beautiful blonde hair. Blondes are typically thought of as fun, stylish and personable. However, if you're growing bored with your golden tresses and could use a change, consider dyeing your hair a darker color. Since blonde hair is so light, dyeing over it is a cinch. Your hair will easily absorb the dye and transform your hair color.
Do a strand test. Mix a small amount of the dye in a bowl. Apply it to a small piece of hair in an area no one can see, such as behind your ear. Wait for the dye to process and rinse it out. Check the color and make sure it looks how you want it to. Give yourself another 24 hours before dyeing the rest of your hair to make sure you don't have any allergic reactions to the dye.
Wash and condition your hair 24 hours before dyeing it, which gives your hair enough time to redistribute the natural oils that help dye penetrate the strands.
Slather some petroleum jelly on your forehead, ears and the nape of your neck. You want to dye your hair, not your skin.
Put your gloves on. Mix the dye ingredients as instructed in the hair dye's directions.
Apply the hair dye generously from root to tip. Put the dye in your hair using the nozzle, then use your hands to run it evenly through your locks. Set a timer for the amount of time stated in the instructions.
Hop into the shower and rinse the dye out. Scrub at your scalp and continue rinsing until the water runs clear.
Let your hair air-dry and observe the color. If your hair hasn't absorbed the color as much as you'd like it to, wait a week and then re-dye it.
Pick a hair color one to two shades darker than your natural eyebrow color. Picking a darker shade ensures that your hair and eyebrow colors match.
Use a semi-permanent hair color, as permanent hair colors can look one-dimensional. You don't want to look like you're wearing a wig.
