To start with, ethanol is an immediate vasodilator. Being a vasodilator, it dilates your blood vessels by relaxing the smooth muscles present in them, thereby increasing the overall area that the blood has to flow through them. And in certain individuals, this vasodilation can be a reason for headaches.

Diuretic

Secondly, ethanol is a characteristic diuretic which means that it increases the outflux of water from your body in the form of urine.
