Is there no way to get bled black dye out of bleached hair?

i have dyed black hair with white bleached highlights in them. the black dye bled into the white and turned it grey/silver..

i was told to rebleach it white, but this is impossible beacuse the hair will definatly break off. very fragile already. my hair stylists told me that after a weeks worth of wash, it will come out, but i havent seen any improvement, and its been 5 days. acualy been getting worse. will the bled black wash out soon...?

I would say listen to your hair stylist. You don't want to ruin your hair anymore! Go back and ask them for suggestions about what to do next.
