Morphology
The meaning is directly built from 'balloon' (to expand or inflate) plus 'head' (the body part), so a learner who knows both words can readily infer a head that feels swollen or inflated. Although metaphorical, the image is literal enough and follows common cross-linguistic inflation/swelling metaphors, making the phrase predictable for a B1 learner.
Etymology
Balloon head comes from the simple image of a head like a balloon—swollen and full of air so it feels tight or floaty. That's why it means 'a head that feels swollen, full, or uncomfortable'.
