I agree that a good cut is essential....and clipping your hair would also help...if it's difficult to clip with the duck bills, then you could try the smallest claw clips...I'm not sure how you apply your products....but scrunching upside down Will help add volume to the crowne area...and I use gloves to SOTC and try to fluff that area up...using gloves will cut down on frizzy, and allow you to put your fingers in your hair
