“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.”

If this doesn’t explain what that baldy was doing with a bottle of Shampoo then nothing will..
