Bleaching black hair?

I have black hair straight from the box and I’ve heard that it is extremely hard to bleach. Normally when re-dying my hair I separate the section that won’t be black but it’s an effort, so this time I was lazy and decided to cover my whole head in black dye, and now I’ll be attempting to bleach parts of it out.
Has anyone done this before that has any tips to make this easier on me or my hair?
Bleach brand recommendations?
Thanks!
