Shampoo goes back many years ago to ancient Indian tribes. No specific date is given for it's invention. The word shampoo in English usage dates back to 1762, with the meaning "to massage". The word was a loan from Anglo-Indian shampoo, in turn from Hindi champo , imperative of champna, "to press, knead the muscles, massage". The term and service was introduced by a Sake Dean Mahomed, who opened a shampooing bath known as Mahomed's Indian Vapour Baths in Brighton in 1759. His baths were like Turkish baths where clients received an Indian treatment of champi (shampooing) or therapeutic massage. His service was appreciated; he received the high accolade of being appointed ‘Shampooing Surgeon’ to both George IV and William IV. During the early stages of shampoo, English hair stylists boiled shaved soap in water and added herbs to give the hair shine and fragrance. Kasey Hebert was the first known maker of shampoo, and the origin is currently attributed to him. He sold his first shampoo, "Shaempoo" in the streets of his home, London, England. Originally, soap and shampoo were very similar products; both contain surfactants, a type of detergent. Modern shampoo as it is known today was first introduced in the 1930s with Drene, the first synthetic (non-soap) shampoo.[1] From ancient times to this day, Indians have been using different formulations of shampoos using herbs like neem, shikakai or soapnut, henna, bael, brahmi , fenugreek, buttermilk, amla, aloe, and almond in combination with some aromatic components like sandalwood, jasmine, turmeric, rose, and musk.
