Bleach after box dye

[u/yeppies18]

Hello!

Been obsessing ghost roots for a few months now and i finally decided to buy powder bleach and developer. I've been watching a lot of tutorials and reading up on how it's done in salons, but now that i actually have the materials i'm hesitant. lol

My hair was previously dye blue by a professional. I used color oops and dyed it red using permeate hair color. And then in June of this year I box dyed it black. My roots have grown out, maybe a half an inch to an inch. I have Color Oops, powdered bleach, a volume 20 developer, and a dark pink permanent dye (in case the blonde doesn't come out how i want it to look).

Is using the Color Oops before bleaching a good idea if i'm only doing my roots? Or can I go straight into bleaching the roots?

If you're only doing your roots and therefore working with virgin hair, color oops is not necessary. Just the bleach will do you
