Morphology

lose + one's + head

The components 'lose' (to cease to have) and 'head' (metonymically used for mind or composure) give a clear metaphorical clue that someone has lost self-control or clear thinking. However, the precise idiomatic sense ‘become very upset/confused or unable to think clearly’ is an extended, conventionalized meaning that a B1 learner may not reliably infer from the parts alone, so it is only partially transparent.

Etymology

Lose one's head comes from the vivid idea of actually losing your head, the part used for thinking and control. When people panic and cannot think, they act as if they have 'lost' their head, so the phrase means 'to become very upset or unable to think clearly'.
