For those whose perms don't turn out well

I heard that even if the same hairdresser uses the same method and products, some hair types turn out well while others don't. I was like, "Huh?" at first, but when I looked at my friend's hair, even though she said she got it done recently, it looked like it had been over six months since her perm—it had completely come undone. It was so fascinating.

Still, they said they were doing it to cheer themselves up.

I was stressed because my perm came out too curly, so I thought I shouldn't say anything.
