Headaches and Vasoco: Headaches occur because of the dilatation of the cerebral arteries. Precluding, dimishing or shortening the duration of this vasodilation will have a beneficial effect on the symptom.
Dr. William Singer

Several ways: Classic vasoconstrictors have several mechanisms to help. The first is by quieting the release of neuroinflammatory chemicals released from the center causing headaches. The second is by interfering with the dopamine relationship between the headache driver and the vomiting center. The third and probably least important is by vasoconstriction.

Decrease pull: The theory behind vascular or migraine headaches is that the blood vessels in the covering of the brain (meninges) are dilated and pull on it, causing pain. The vasoconstrictors reduce this.
