The History of Shampoo: From Soapnuts to the Brighton Baths

Few everyday words carry as much history as shampoo. Today it means a bottle in the shower and a quick lather before work. For most of its life in English, though, it meant something quite different: a vigorous, oiled massage of the head and body, a treatment rather than a product. The story of how that massage became a liquid detergent runs from ancient India through a Regency bathhouse on the Brighton seafront to a chemist's shop in Berlin and the synthetic chemistry of the 1930s.

A word that means to press

The English word shampoo dates to 1762. It comes from the Hindi cā̃pō, itself traced to a Sanskrit root meaning to press, knead or soothe ^[1]. The historian writing for History Today gives related forms, champoo, champi and champna, all carrying the sense of kneading or massaging ^[4]. The first English speakers to use the word were describing a technique they had encountered in India, not a substance.

That older meaning lasted a long time. Before the 1860s, shampooing referred to therapeutic massage of the whole body, usually before bathing ^[4]. The meaning of shampoo as washing the hair is first recorded in 1860 ^[1], and it did not settle into its modern, hair-only sense until late in the nineteenth century ^[4]. When you read the word in a Georgian or early Victorian source, it almost never means what it means today.

Soapnuts, shikakai and amla

The Indian subcontinent had cleansing hair preparations long before the English word existed. Ancient Indian texts describe the fruit of the soapberry tree, Sapindus, as ksuna, and call its lather phenaka ^[1]. Soapberries, also known as soapnuts, contain saponins, natural compounds that foam and lift oil much as a modern detergent does ^[7]. Their scientific name even means "soap of India" ^[7].

A well-known early recipe combined boiled soapnuts with dried Indian gooseberry, or amla, and other herbs, using the strained liquid to wash the hair ^[1]. Shikakai, the pods of a climbing shrub, was another favourite. Archaeobotanists have found traces of shikakai mixed with soapnuts and amla in pre-Harappan levels at Banawali in present-day Haryana, dated to roughly 2750 to 2500 BCE, which makes it some of the oldest physical evidence of hair care in South Asia ^[6][1]. Hibiscus flowers, ritha and arappu were also used ^[1].

Washing hair around the world

India was not the only place with a sophisticated approach to clean hair. Akkadian and Neo-Assyrian texts from ancient Mesopotamia refer to medicated washes, and Neo-Assyrian tablets record a medicated shampoo used to treat scalp eruptions ^[1].

Elsewhere, people used whatever cleansing plants and minerals were at hand. In Indonesia, early shampoos were made from the burned husks and straw of rice, whose alkaline ash formed a lather; the hair was then oiled with coconut oil to replace the moisture the ash had stripped out ^[1]. In the Philippines, the soaked and rubbed bark of the gugo vine produced a cleansing foam that is still used in hair tonics ^[1]. The Costanoan peoples of coastal California used extracts of the coastal woodfern, and in the Andes the soapy saponin washed out of quinoa before cooking was used to clean hair ^[1].

Europe's record is thinner. The Gauls made a soap from goat fat and beech ash that was used to brighten hair, while the Romans, who did not make soap in the modern sense, cleaned their bodies and hair with mixtures of oil and sand ^[1].

Wigs, oils and powders

In seventeenth-century Europe, fashionable men and women of the upper classes wore wigs, and washing the natural hair with water was widely discouraged. Instead, hair was dressed with oils ^[1]. In the eighteenth century, powders made from starch were used to absorb oil and scent both hair and wigs ^[9]. These were the ancestors of the dry shampoos that came back into fashion in the early twentieth century, a story we tell in our journal piece on hair powders in 1910.

Hair oils remained a mainstay well into the nineteenth century. Macassar oil, sold from the 1790s by the London barber Alexander Rowland, was one of the first products in Britain to be advertised nationally. It transferred so readily from heads to furniture that, from about 1850, washable cloths called antimacassars were draped over the backs of chairs to protect the upholstery ^[8].

Sake Dean Mahomed

The man most often credited with bringing shampooing to Britain is Sake Dean Mahomed. He was born in 1759 in Patna, in what is now the Indian state of Bihar, and served with the East India Company's army, by his own account as a trainee surgeon ^[2]. In 1784 he travelled to Cork in Ireland, where he studied English and married Jane Daly ^[2]. In 1794 he published The Travels of Dean Mahomet, which made him the first Indian to publish a book in English ^[2].

After moving to London, Mahomed worked for Basil Cochrane, a wealthy former East India Company official who had installed a steam bath in his house in Portman Square and promoted its medical benefits ^[2][4]. According to History Today, Mahomed presented himself to Cochrane as an expert in Indian therapeutic massage, and his family later claimed that his "champi or shampooing" was one of the baths' main attractions ^[4]. In 1810 he opened the Hindoostane Coffee House near Portman Square, the first Indian restaurant in England. It closed in 1812 because of financial difficulties ^[2].

The Brighton baths

In 1814 Mahomed moved to Brighton, then at the height of its popularity as a sea-bathing resort, and opened a bathhouse near the seafront ^[3]. Sources differ slightly on the exact site and opening date, but they agree on what it offered. Bathers could soak in sea water that had been piped in and warmed, a far more inviting prospect than being dipped in the cold Channel ^[3]. Mahomed also introduced treatments from India, including "Shampooing with Indian Oils", a form of aromatherapy massage, and the Indian Medicated Vapour Bath, in which clients sat and breathed steam infused with medicinal herbs ^[3].

His advertisements were confident. In a local newspaper he described the vapour bath as "a cure to many diseases and giving full relief when everything fails, particularly Rheumatic and paralytic, gout, stiff joints, old sprains, lame legs, aches and pains in the joints" ^[3]. An advertisement in the Sussex Advertiser on 1 May 1815 added that "Mr. and Mrs. Mahomed Possess the Art of Shampooing" ^[4]. Jane was a partner in the business and superintended the ladies' baths ^[2].

The baths were a success. Mahomed became known locally as "Dr. Brighton", hospitals referred patients to him, and he was appointed shampooing surgeon to both George IV and William IV, treating them at the nearby Royal Pavilion ^[2][3]. He published his own books on the subject, including Shampooing; or, benefits resulting from the use of the Indian medicated vapour bath, which went through editions in 1822, 1826 and 1838 ^[2]. A Brighton historian writing in 1862 claimed Mahomed had treated a thousand cases by the end of 1815, though that figure comes from an admiring local history rather than an independent count ^[4]. The business eventually ran short of capital and was put up for auction in the late 1830s ^[2].

It is worth being clear about what Mahomed was selling. His shampooing was a massage with oils inside a steam bath, aimed at aches, stiffness and general health. It was not a bottle of hair soap. But by making the word fashionable in one of Britain's most fashionable towns, he helped give English the name for the product that would follow. Brighton & Hove Museums still hold a collection of portraits, costume and personal objects connected with him ^[3].

From massage to hair wash

As the word drifted from massage toward hair washing in the second half of the nineteenth century, the practice itself was simple. Hairdressers in England boiled shaved soap in water and added herbs for shine and fragrance ^[1]. Ordinary bar soap was harsh on hair and, in hard water, left a dull film, which created a market for something better.

Commercially made shampoo appeared around the turn of the twentieth century ^[1]. In 1900 the German perfumer and hairdresser Josef Wilhelm Rausch developed a liquid hair-washing soap in Emmishofen, Switzerland, and named it "Champooing" ^[1]. By 1914, American magazines carried advertisements for products such as Canthrox Shampoo, shown being used by young women washing their hair in a lake at camp, and Rexall's Harmony Hair Beautifier and Shampoo ^[1].

A name sometimes repeated online, Kasey Hebert, is often described as the first maker of shampoo. We were not able to find a primary source for that claim, so we have left it out of the timeline.

Schwarzkopf and the powder in a bag

In Berlin, a chemist named Hans Schwarzkopf opened a shop selling paints, drugs and perfume on Passauer Strasse in Charlottenburg in 1898 ^[5]. The company story has a customer asking him to order a powdered shampoo she had seen in Britain. He eventually decided to make one himself, and after several years of development launched a powder that was dissolved in water before use. It sold for 20 pfennigs a bag, one wash per bag, and was more convenient than any hair-washing soap then available ^[5]. His biography dates the launch to 1904; other accounts give 1903 ^[5][1]. It became the first branded hair cosmetic product in Germany ^[5].

Schwarzkopf died in 1921, and his widow Martha Schwarzkopf ran the company until 1935. In 1927 she founded a hair research centre, and the same year the company produced the first mass-produced liquid shampoo ^[5][1].

Detergents replace soap

Until the 1930s, shampoos were essentially soaps. They shared the same naturally derived surfactants, and the same drawbacks in hard water. That changed with Drene, launched in the 1930s as the first shampoo to use synthetic surfactants in place of soap ^[1]. Synthetic detergents rinsed cleanly in hard water and opened the way to the clear, foamy liquids that dominate bathroom shelves today.

A modern shampoo is typically built on a surfactant such as sodium lauryl sulfate or sodium laureth sulfate, combined with a milder co-surfactant such as cocamidopropyl betaine, and thickened with ordinary salt ^[1]. Citric acid is commonly used to bring the pH down to around 5.5, because the scales of the hair's outer layer, the cuticle, lie flatter at slightly acidic pH, which makes hair feel smoother and look shinier ^[1]. Baby shampoos use less detergent, a near-neutral pH and gentler surfactants to reduce stinging if the product runs into a child's eyes ^[1].

Conditioner followed a parallel path. The perfumer Edouard Pinaud presented a softening product called Brilliantine at the 1900 Exposition Universelle in Paris, and over the twentieth century silicones, fatty alcohols and cationic polymers gradually replaced simple oils ^[8].

Dry shampoo also returned in a new form. The first commercially produced dry shampoo powders were sold in the 1940s, including a brand called Minipoo, marketed for "surprise dates" or for days spent sick in bed ^[9].

Shampoo and the scalp

Shampoo is now also a delivery system for medicine. Anti-dandruff shampoos contain antifungal ingredients such as ketoconazole, zinc pyrithione or selenium disulfide, which reduce the yeast Malassezia associated with flaking ^[1]. In the United States, shampoos intended to treat medical conditions such as dandruff or an itchy scalp are regulated as over-the-counter drugs rather than cosmetics ^[1]. Contact allergy to shampoo ingredients is also well documented, and patch testing can identify the culprit ^[1].

This is educational history, not medical advice. Persistent flaking, itching or hair shedding is worth having assessed by a qualified professional.

The history of shampoo in one paragraph

People have cleaned their hair with plant saponins for at least four and a half thousand years, from soapnuts and shikakai in South Asia to rice ash in Indonesia and quinoa water in the Andes. English borrowed the word shampoo from Hindi in the eighteenth century to describe a massage, and Sake Dean Mahomed made that massage fashionable in Regency Brighton. Only from 1860 did the word begin to mean washing the hair. Commercial shampoos appeared around 1900, Schwarzkopf's powder became Germany's first branded hair cosmetic, the first mass-produced liquid shampoo followed in 1927, and synthetic detergents in the 1930s created the product we use today.
