Can I use direct dye on a chemically burnt scalp?

Last week I got 10vol bleach put on my roots and it ended up burning so much that i had to ask for it to be taken off. My scalp was so sore for a few days but now its just flaky and scabby but doesn’t hurt. I got my roots retouched so I could dye them blue for a concert that i have tonight and i only use direct dye. Can i do this or is it going to make my scalp worse? im not a professional ofc but to
me direct dye seems like it wouldn’t do much harm and especially if my scalp feels fine.
