(Question for hairstylists) is bleach supposed to itch EXTREMELY bad & burn a little on your head?

I got my hair done and I’ve had it done several times with someone else, I love to do vivid hair colors, but this new girl I went to as soon as she started applying the bleach to my hair, it was EXTREMELYYYY itchy I couldn’t stop shaking in the chair, I couldn’t stop itching, it was HORRIBLE then it burned a little, so I don’t know why that happened, and I’m pretty sure there’s a reason why it happened..

Do you hairstylists have an idea on why that happened?
