Cindy and I were wondering this morning where the word “shampoo” came from. I guessed French, probably something to do with “eau” (water). Google found an entry at Etymology Online indicating that the word’s origins are much more interesting:

1762, “to massage,” from Anglo-Indian shampoo, from Hindi champo, imperative of champna “to press, knead the muscles,” perhaps from Skt. capayati “pounds, kneads.” Meaning “wash the hair” first recorded 1860. The noun meaning “soap for shampooing” first recorded 1866.
