I need help

You probably could, I don't see why not - but how quickly in succession did you bleach, bleach again and then dye it? It might need a rest for a while.

You might find that the black dye fades towards the ends anyway over bleach, mine is dyed brown over bleach and it doesn't stick as well as it does at the top on my virgin hair.

It depends where the dark patches were from the bleaching.

If they were in the ends, or where you want your hair lighter, then no.

If they were where you want it to stay dark, it might. It depends on the dye and how you've treated your hair since dying.

I re bleached the dark patches after 6 months didn't make a difference the black dye fades away in 3 months If I dye it brown doesn't last a month  I thought I'd ombre it under the dark patch of hair but I'm  defo going to give it a rest for month

I have to dark patches on each side near my  ear  I was going to use the hair dye removal under the patches just ombre it since I can't dye it one colour because of the patches
