Etymology: Trichophagia is a compound built from two Greek elements: "thrix" (genitive "trichos"), meaning hair, and "phagein," meaning to eat, which gave the suffix "-phagia" for the act of eating something. Put together, the word describes eating hair, and it belongs to a family of modern medical terms that pair a Greek stem with "-phagia," such as geophagia (eating earth) and pagophagia (eating ice). The Greek roots are ancient, but the compound itself is a later coinage. Medical and psychological writers assembled it from classical parts to name a specific compulsive behaviour, so the word is a technical creation rather than something ancient Greek speakers used. Its meaning stays close to its parts: the eating is the defining act, and the clinical concern lies in what happens afterward, when swallowed hair can collect in the digestive tract.

Synonyms: hair eating, hair chewing
