Step 1
Get your hair professionally dyed. Black hair dye is very rough on hair and if not done correctly, you cause a lot of damage to your hair. In addition, if you get it professionally done, it'll probably last longer.

Step 2
Choose a dark black hair dye if you're going to dye your hair black at home. However, follow the directions carefully, avoiding leaving the chemicals on your hair for too long and be prepared for the color to fade quickly.

Step 3
Make sure black hair will work with your skin tone. If the veins on your arm are green, you have a warm skin tone. If they're blue, you have a colder skin tone. In general, black hair looks best on people with cooler skin tones.

Step 4
Know that removing black dye from hair is very difficult and involves stripping the color from the hair and then re-dying it a different shade. Make sure you want black hair before you change the color of your brunette hair.

Step 5
Consider dying your eyebrows too, especially if you're a lighter brunette. It looks odd to have hair one color and eyebrows another color. See an aesthetician about dying your eyebrows before you attempt to do it at home.
