I still feel kinda new to all this but...I wonder if maybe when you're plopping your pulling on those front, side strands of hair (or they're getting flattened with the towel) and thats why they're a little straighter than the rest of your hair. I think that is what is happening to me. Maybe you could experiment with leaving the very front strands out of the towel when you plop.

I love your hair though. Very nice color and curl. I wish my hair was that length.
