How to reverse a perm 🙄

So in May...my hair was to my bootycrack.

My sister and I were bored in quarantine and she asked if I would perm my hair so she could see what it would look like if she got one.

I did it. I hated it. I chopped my crispy hair up to my shoulders.

It has slowly gotten slightly less curly but is there any way to just totally reverse the perm without perming it straight?
