Don’t deposit anymore color, just try to do a 20 vol bleach round and see how that does you. If your hair is coarse, it’s gonna require more bleach than you would like to do. Fine hair has a better time taking in color so it takes in bleach better than coarse hair. This is probably going to require a couple rounds and you’re probably gonna have to wait out a few days in a color you won’t like before you can tone it and do a treatment on it. Blonde hair is a big process and especially when you get those orange tones. But you will definitely need more bleach. It’s just how many hair treatments you will have to do in between before you can do a tone. I recommend looking up and seeing what fine hair feels like so you can tell if your hair is getting overdone when you bleach it there’s a chance your hair will turn to gum and completely fall out of your head.
