HAIR FALLING OUT!!! HELP!!! 😭😭

I put in a deep conditioning thing my mom gave me. I read the directions and did exactly as they said. But when I got in to wash it off, it began to burn and my hair started falling out in chunks!! After getting it out as quick as I could, it started to slow but hasn’t stopped... I have coconut oil sitting in it, but I think it is still breaking. I read that I must be allergic to it. My scalp is red and burning. It is the middle of the night and I don’t have a car today. My mom borrowed it and she is gone... Any suggestions on how to stop it so I can get to a salon to fix it?? Please, I’m so upset! The redness and burning have gone down and almost stopped, but my hair is definitely breaking still.
