What does shampoo mean?
Shampoo is a noun and verb centered on washing the hair. As a noun, it names a liquid preparation—often containing detergents, conditioning agents, and fragrance—that is worked into wet hair and rinsed away; it can also denote the act of washing the hair this way. As a verb, shampoo means to wash the hair with such a preparation. The everyday sense is used in standard British and American English, though the word also reflects a regional history in South Asia. Its origin differs notably from its modern product meaning: English took it from a Hindi term associated with pressing or massage, and its earliest European uses referred to massage rather than hair-care products. It later developed the now-familiar meanings connected with washing and hair cleansers. Shampoo is worth knowing because it preserves a striking shift in cultural and commercial history while remaining an ordinary, easily understood household word.
A liquid preparation used to cleanse the hair and scalp; also, less commonly, the act of washing the hair with such a preparation.
"This shampoo is designed for dry or damaged hair."
When referring to the washing act, the noun is often used in more formal or traditional expressions such as “a shampoo and set.”
To wash the hair and scalp with shampoo.
"She shampooed her hair before the concert."
The usual form is “shampoo one's hair”; “to shampoo” also means “to shampoo one's hair.”

Shampoo began as a massage: its modern hair-care meaning emerged only after an Indian therapeutic practice became a European luxury.

Where does shampoo come from?
English borrowed the word from the Hindi चाँपो (chāmpo), meaning “press” or “massage,” during the eighteenth century, when Indian massage practices were becoming known in Europe. Early English uses referred to a therapeutic massage; the meanings connected with washing the hair and with hair-cleansing preparations developed later. Portuguese xampu and Malay syampu are further adaptations of the same Indic source through international borrowing.
