QZ vs HS

Heya,
everytime i Quick Zoom someone (and i really shoot him cuz hes doing the "omg some nub shot me" move(and i see blood)) and he headshots me at the same time, im dead and i did 0 damage to him. Why?... Even when pings are about the same the headshot always wins >< thats very very annoying already
Please explain me why the headshot always wins over the quick zoom ;(
