Where does the name 'shampoo' come from?

Oddly enough, the origin of ';shampoo'; has nothing directly to do with hair (and does not, puns aside, involve our modern word ';sham,'; meaning ';phony';). ';Shampoo'; comes from the Hindi word ';campo,'; meaning ';to press,'; and a ';shampoo,'; which entered English around 1762, was originally a full-body massage. In fact, until the mid-19th century, asking for a ';shampoo'; would get you pummeled by a masseur (or masseuse) and slathered with oils and lotions. Only lastly (if you lasted that long) would your hair be washed. By about 1860, however, ';shampoo'; had attained its exclusive modern meaning of ';washing the hair.'; Shortly thereafter, ';shampoo'; began to be used as a noun meaning either an act of shampooing or the special soap used on the hair.
