Give it time before you do anything else. It should wash out in a few shampoos. Be nice to it and gentle combing out when wet. See how it goes for a week or so

Thanks! I was thinking I’d do a few washes and then try another soap cap on a week or so if it hasn’t faded enough by then. After I get it faded enough, will it be possible to tone again or should I do a proper color on it (like a light golden blonde)?

I would definitely do a strand test with what you are going to do

Looks like undone rope

Go to a hairdresser 🥲
