Hair Dye Answers

if so, how long should the dye stay in the brows & how long will the color stay in the brows?
do i have to constantly dye it from now on?
does it have to be a shade darker than the head hair color?

I originally have dark brown hair, & I dyed my hair black (worst mistake I’ve ever done to my hair), I want to remove black hair dye. Would Loreal Color Zap work? If it does, would my hair turn back to dark brown, or would it turn into some different color since Color Zap does contain a small amount of bleach?
Thanks.

I currently have black hair, but i want to go back to my natural color, which is a Ashy Dark Brown. I heard that Extra Bleach Extra Blonde works well for lightening/bleaching hair.
But my question is, if i use that is it alright to use color hair dye afterwards? Do i have to wait a couple of weeks before i can color it? Or if i do it right after i bleach my hair will it damage it even more or not turn out right?
Thanks,
Michelle.
