I am wondering if anyone else has this "problem." My crown area is the most silkiest and finest part of my hair. It's not very curly as the rest of my hair but more wavy. That would seem to make it easy to straighten, right? Nope! It's the part that holds on to the wave like it's in a competition or something. I don't understand it. No matter what I do to straighten my hair, it gets straight everywhere and even there - except, there's ALWAYS traces of waves left! Why is the wave soooo strong and resistant in this section? Anyone else have this problem? What do you do to ensure the wave completely disappears. I believe my hairtype is 3c but I would classify my crown area as closer to 3b.
