Origin of shampoo

1755–65; earlier champo to massage < an inflected form of Hindi cāmpnā literally, to press

Explanation

Got dirty hair? Get yourself some shampoo and jump in the shower! Shampoo is soap made especially for washing hair. Use shampoo for the liquid soap itself, or for the act of using it: "I don't have time for a shampoo, so I'll wear my favorite cowboy hat." It's also a verb: "I love the way my hair smells after I shampoo it!" You can also shampoo a carpet—or a dog. Shampoo originally meant "to massage," stemming from a Hindi root, champo, "press or knead muscles."
