What volume / brand do I use?

Na

I’m working with virgin roots that are about 3 inches long, and about 8 inches of hair that was first box dyed with a light red and then had Paul Mitchell color in a darker red on top.

It’s been about three months and while the ends are definitely red, it’s been fairly faded.

If I wanted to lighten the ends, what volume bleach should I use for the least damage? Will the color even lift?
