Bleaching and dying it green again after dying it natural colour

Heya there! I bleached and dyed my hair dark green a week ago (The undersides on the back and sides). Unfortunately my internship requirements (which I got just now) require me to have my natural hair colour (which is starting next week). I have a N2/3 2a hair that is not porous. I got it done at a hairdresser and not sure about the bleach, but the colours where from Keune.

The internship gets over in a month. So would it be a good idea to bleach and dye it green again or would the damage be really bad? Cheers!
