Top back hair wavy, front and bottom curly???

Hello to All!I was wondering if the back side of my hair is transitioning or something else, the front and bottom of my hair is curly which I don't understand. I also have tried scrunching method, plopping, clips, and so on, but I am not sure why the curls don't match the front and bottom. Please comment if you know whats going on or have any other recommendations!Thank you so much!!
