Often it's dehydration.   Its a good practice to drink a glass of water at fist sign of a headache.

Neuroinflammation in brain tissues can lead to headaches/migraines. Others neurological factors (ie emotional stress, traumatic brain injury) can also trigger neuroinflammatory pathways.

There are over 200 types of headache (including migraines).

which nerves give rise to the pain of headaches

Trigeminal nerves: ophthalmic, maxillary and mandibular

Trigeminovascular system-activation initiates cranial parasympathetic-mediated cerebral vasodilatation and peptide-release from trigeminal nociceptive afferents.

The following increase in vascular permeability results in plasma protein extravasation, mast cell degranulation and further dilatation of cranial vessels via neuroinflammatory prostaglandin-release.

You are right, despite containing billions of nerve cells, the brain has no internal sense of pain or touch. But, the structures around the brain, like the meninges, are richly endowed with sensory nerve endings capable of transmitting pain sensations which are referred to the head; that means that you experience activity within these nerve fibres as pain coming from within and around your head, so migraines, meningitic infection or a bleed around the brain, which all involve irritation of the meninges, all produce pain. But there are many other reasons for headaches, including tension and stress most commonly, dehydration, menstruation, raised intracranial pressure and so on. So, like backache, it's a simple symptom representing a complex set of underlying causes.
