so about 6 months ago  I dyed my hair blonde and last weekend I went to get my roots done and toned it to be light and bleach some of the yellow strands in its but nothing changed with my hair It looks the same. I hate it and can't stand it anymore so I was wondering how long I should wait to dye my hair again cause I wanna go back to brown but I'd just use box dye cause I really don't feel like spending $100 at some salon again
