If you push down on your head with your hand, sure, it'll put pressure on your neck...
but if you put an expanding force between the top of your head & the inside of the helmet, no force will be transfered down to your neck... only the top of your head & your cheeks as the helmet lifts off & they're in equal & opposite directions, canceling each other out.
