A very heavy hat and a very sharp cattle grid may yet be the answer.
Chris, try this.
When hitting the ball, dont worry about your head coming up, it's supposed to.
Just keep the angle set between your back and hips a little longer.
I'd say its not your head coming up that's the problem.
Stay in your posture longer and that will keep your head where it shoud be.
