I have a lower layer hair that is less curly than the top and my nape hair is clearly wavy rather than curly. Usually goes from 2C styled and damp to 2B dried to even 2A four days after washing... And yes, I have a hard time accepting it, partly because I don't know if it is how the hair "should" behave or if it's damage and partly because I don't know how to handle it. I cut it a bit shorter yesterday so that it doesn't stick out but if I end up with some hair hanging it sometimes still looks like just forgot to curl it or something... :/
