Burnt my hair with hairspray

I hate myself because I knew I wasn’t supposed to do this! Last Saturday I had straightened my hair and put in hairspray afterwards. I slept with my hair like that. Morning after I decided to curl my hair ( I didn’t wash my hair) so I technically curled my hair while having hairspray from yesterday and now my hair took damage and it has left a few stringy hairs on top of my head and is very much dry and damaged at ends. Every time I pull those top pieces they curl and my hair isn’t curly it’s frizzy but not curly. 💔 when it’s wet or dry it looks so fragile and so so thin! Any advice would be helpful!

The only things I’ve been doing is washing my hair every 2-3 days, braiding it every night, no heat whatsoever and oiling it with argan oil.
