How do you train your hair to curl under after a recent haircut?

I just got my hair cut to my chin -- I love it!! But I'm having trouble keeping the back ends to stay flipped under... I blow dry them to bend under and that seems to fail... then I used a curling iron to tame the ends and it still flips up, not under... :-\ Is my method wrong?How do you train your hair to curl under after a recent haircut?
You're doing the right thing but now get a round brush and as you blow dry your hair, use that to also curl it under. You have stubborn hair like me. I feel bad for you! :) Just do those to things and use a light gel when you blow dry your hair. That should be all you need. Good luck!
