I dyed my hair black 2 months ago, and I'm now tired of the color. What's the best way to remove the color?

The only way I would see to remove the color, honestly, is to go to a salon, have the hair bleached and stripped, which is a damaging process, and then dye it another color. It's important to make sure you can live with a hair color as long as it takes to grow out before you dye your hair. :(
