This happened to me recently. I go to a beauty school so cost isn’t really an issue, they did a mild bleach wash and I was pleased with the color after that. You could get the products to do this yourself at home at Sally’s or another beauty supply store and ask them for guidance or Google the process. It doesn’t damage your hair the way a true bleaching would do, my hair was a little bit coarser but not terribly so.
The other alternative that works a little slower is to buy a bottle of T-gel shampoo and use it daily for a few weeks - it will fade the color noticeably.
