Okay so i posted a couple of days ago about going blonde and finally getting rid of that awful brassy orange color in my hair. But now i have another problem. I went to the salon yesterday my stylist used the highlight cap to pull out enough hair and bleach it so now my hair has no tint of red/orange neither does it look brassy at all! Yay But now my hair is too ashy its a medium brown ash but i want it lighter and i want to tone down the green tint to it and add a bit more of yellow. I told this to my stylist and she said she would try to fix it she kind of fix it but not really it just go lighter to a dark ash blonde but there is still a lot of green tint to it and almost no yellow-whiteish tint i told her i want to tone down the green tint and have it blonder and she said she couldnt fix,that i should wait and maybe give the color a try, it i know i should have insisted but she refused to fix it anymore. I have no money at all to go to another place so lets cross out that option can you please tell me what can i do to add lil bit more of a blonde yellow-white color to it and get it lighter, what kind of color should i use? Ive wash it a couple of times but it has remained the same. please help me out!

Im desperate
