Using herbs and extracts to wash hair has been around since ancient times in India, which is where the name 'shampoo' as a hygienic haircare product originated in the 1860s. It derives from the Hindi word cāmpo, meaning 'to press', and referred to a form of therapeutic body massage, one often witnessed by 18th-century British visitors to India. The term gained popularity thanks to Sake Dean Mahomet, a celebrity ex-soldier from Bengal, who was appointed Shampooing Surgeon to King George IV in 1822.
