While companies are constantly improving their home hair coloring products and making them easier to use, the following list outlines the times that you should go to a salon and leave your hair in the hands of a professional:

1. Your hair is severely damaged. It breaks easily, and your brush and bathroom floor have more hair on them than your head does.

2. You want to lighten your hair more than three shades. Even if your hair doesn't appear to have any red tones in it, all dark hair contains some red pigment. Therefore, lightening your hair in one step will most likely turn your hair an unattractive shade of orange. A professional colorist can prevent this by using a toner to cancel out redness, thus providing a more attractive golden hue.

3. You're feeling dramatic and you want to do something crazy, like go from blonde to black. At least go to the salon for a consultation about what colors will look good with your skin tones.

4. You've already colored your hair, you screwed up, and you want to fix it. Don't stay in hiding, attempting again and again to correct your own mistake.
