does coloroops work on black hair?

[xxprincessxx]

I'm the kind of person who likes changing their hair color a lot but every since I dyed it black I haven't been able to. A few weeks ago a friend and me tried to get it out with a bottle of bleach but it only worked on part of my hair, so we had to dye it back to black. I saw the coloroops stuff at the store and was wondering if it would take the black out of my hair, so I could dye it to a different color.

Yes it will, I used to dye my hair jet black and it lightened my hair significantly. Just make sure to get a few bottles just in case, you can return anything you don't end up using.
The bleach should have worked, did you have enough? If you put more bleach on some parts of your hair than others then it will become uneven. Make sure you're leaving the product on long enough as well, check your hair frequently while it is processing.
