Hi everyone, it's my first time posting here after always coming back to read, nice to meet you guys! :)
I've been hopeless going for pink hair and decided to ask pink hair experts.
My hair adventure began last year when I finally decided to go pastel pink. Being asian hair and making mistake of doing henna before, it took me a long time, a lot of money, and much damage until I got to the blonde that was light enough.
As I don't have any experience with bleaching hair I went to a salon, and at that time she broke base to brown instead of bleaching the root(almost an inch), which turned a bit brassy later on.
About a month ago, I finally put pink (Ion Rose mixed with a little bit of Ion purple) and was loving it so much. Then it faded really quick, and second time I mixed a lot more purple, and later my hair faded into ashy blonde with a little bit of pink inside as it was a bit more stubborn to fade. At the point of dyeing, I had roots that's about half an inch of black and almost an inch of brassy brown, and I ended up putting the dye on the roots as well trying to cover whole head evenly.
So here comes the problem.. I thought I should go back to salon at least for root bleach and do pink again myself. She put bleach on my root for 45 minutes, and she washed my hair. Then I was terrified to find that I had NEON orange/salmon band that's about an inch thick around my whole head, like the color in this picture (I tried to find a picture online that looks like what my came out, please let me know if it causes any issue I will put it down):

She put another session of bleach just on that band, but it did nothing. Then she put lavender on my entire head hoping it will kill orange, but I still have very obvious band, just a bit less bright as in the pictures (It's a bit more pastelized due to phone camera):

She blamed my pink dye and told me I should only use Pravana, nothing else. I bought a bottle of Special Effects Atomic Pink as I heard it has stronger staying power, but she didn't know the brand Special Effects and told me not to use it.
Is it really the pink dye that made my roots neon orange? Have you ever had that experience? Is it possible that pink faded on blonde but was still sticking on the roots and bleached to neon? Am I supposed to never put dye on my roots that's to be bleached? Or could it be from breaking the base? She charged me 200 dollars for doing all this for my hair, and I'm not happy with it. Is there anything I can do about this root?
I'm really afraid what I will look like when the lavender fades, and that I would never be able to go back to nice blonde base as even bleach is not helping it..
Thanks for reading the long post, and I will appreciate any advice! Please help!
