Chapter 3 · 1906

The first permanent wave

On a London morning in 1906, a German hairdresser named Karl Ludwig Nessler wound a woman's hair in spirals around brass rods, soaked it in an alkaline paste, and clamped an electric heater onto each rod. He turned on the current. Hours later, when the rods came down and the hair was washed, the curl was still there — and it stayed through the next wash, and the one after that. For the first time in three thousand years of trying, a curl had been made to last. It had cost the woman in the chair blisters on her scalp, and it would cost Nessler's clients a small fortune. The age of the permanent wave had begun.

The permanent wave, like every great invention, is usually attached to a single name and date: Nessler, 1906. Both are correct in the narrow sense, but both require care. Nessler is frequently confused in the popular record with a later American entrepreneur who shared his adopted name, and the precise circumstances of his demonstration are reported with more confidence than the evidence supports. What is not in doubt is the result: a machine, a paste, an electric current, and a curl that survived water. Everything that followed — the brass salon machines of the 1920s, the cold-wave chemistry of the 1940s, the digital perms of the present — descends from the morning Nessler switched on his heater and the curl did not wash out.

The man before the machine

Karl Ludwig Nessler was born on 2 May 1872 in Todtnau, a small town high in the Black Forest of Baden, just beneath the Feldberg. His father was a cobbler. The boy is said to have worked as a shepherd in the hills above the town, and to have drawn from that work the first germ of his idea: that wool, unlike human hair, is naturally crimped, and that plant tendrils curl ahead of rain. Whether or not the shepherd story is literally true, it captures something essential about his cast of mind. He was not a chemist, nor an engineer, but a barber's apprentice who never finished his training, and who spent two decades reasoning, by analogy and trial, toward a mechanical answer to a chemical problem.

He began an apprenticeship with a village barber in nearby Schopfheim-Fahrnau but dropped out within months. What followed was the classic itinerary of the ambitious young German craftsman of his generation: work in Basel, in Milan, and finally Geneva, where he completed his apprenticeship in an elegant salon, learned French and Italian, and adapted to the French-speaking world by adopting the name Charles Nessler and spelling his surname Nestle. From Geneva he moved to Paris, and from Paris — by way of experiments on long-suffering volunteers — to London. The Swiss and French years were also the years of experiment: Nessler was testing what heat and alkali together could do to a shaft of hair that heat alone had never done — hold a shape past the next washing.

Nessler has spent years testing alkaline dressings and heated rods on volunteers. The chemistry of keratin — the disulfide bonds whose rearrangement is the actual secret of a lasting wave — is not yet understood in the salon, but Nessler has reasoned empirically to the same place the chemists will reach by theory: that an alkali applied under sustained heat can reshape the hair. He needs a machine that will deliver that heat, rod by rod, to a whole head. He builds it himself.

A name, and a confusion to dispel

Before the demonstration itself, one point of identity must be settled, because it is the source of more garbled accounts of the permanent wave than any other. Karl Ludwig Nessler — the hairdresser of Todtnau, the inventor of the machine permanent wave — is the same man who later traded in the United States as Charles Nessler and Charles Nestle, and who held the 1902 British patent for artificial eyebrows and eyelashes. He is not a different person from "Charles Nestle." Nessler, the permanent-wave man, is the eyelash man: his New York Times obituary in 1951 noted plainly that "he also invented false eyelashes." When a secondary source credits "Charles Nestle" with the eyelash patent and "Karl Nessler" with the permanent wave, it has split one man in two. The hairdresser of Todtnau holds both honours.

Karl Nessler, Charles Nessler, and Charles Nestle are one man — the barber's apprentice from the Black Forest who patented both the first permanent wave and the first modern false eyelashes. Popular accounts that divide him into two inventors have simply misread his adopted names.

The London demonstration, 1906

Nessler moved to London, married Katharina Laible — the subject of his early Paris experiments — and established himself on Oxford Street, in the fashionable salon district. There, on 8 October 1906 — though the Library of Congress records the first successful demonstration on 8 October 1905, and the year is contested in the sources — he gave the first public demonstration of his permanent-wave machine before an audience of leading London hairdressers. The reception was cool. The method did not fail — the curl held — but Nessler's English colleagues regarded him as a competitor for their own clients. A German-born hairdresser on Oxford Street, threatening to make their daily Marcel-wave business obsolete: the trade closed ranks.

The commercial outcome was the opposite of the professional one. Whatever the hairdressers thought of the man, the women of London wanted what his machine could do, and the perm was an immediate success with the paying public. He patented the machine in London in 1909 (British patent GB190902931A, "A New or Improved Process of Waving Natural Hair on the Head," filed 6 February 1909), with further improvements in 1912 and 1914. The date now fixed to the invention is the 1906 demonstration; the legal protection followed three years behind it.

Nessler demonstrates the machine permanent wave to an invited gathering of leading hairdressers. The trade is hostile; the clientele is not. Within a few years the treatment is a London sensation, and Nessler holds the 1909 British patent that will define the field until the war interrupts his work and carries him to America.

The machine

The apparatus was unlike anything the nineteenth-century salon had contained. Its principle was the spiral wind: each section of hair was divided, tied close to the scalp, moistened with an alkaline paste, and wound in a continuous spiral along the length of a brass rod, so that the rod ran through the curl like the core of a ringlet rather than forming the ringlet around its own girth. The rods projected out from the head — contemporaries compared them to horns — and to each one Nessler clamped a self-constructed, electrically heated tong, of the kind he likened to a small waffle iron. The tong had to be held in place throughout the heating, its temperature judged by hand and eye. When the current was switched on, the brass rod grew hot, the alkaline paste activated, and the combination of heat and alkali did what heat alone had never done: it reshaped the keratin.

A brass rod was fixed projecting from the head — contemporaries compared the array to "horns" — and the hair was wound along its length in a continuous spiral, so that the rod passed through the curl like a core. An electrically heated tong, clamped over each rod, supplied the sustained heat that, with the alkaline paste, reshaped the keratin. (Author's schematic, after the description in Wikipedia's biography of Nessler and period accounts of the 1909 machine.)

Overhead, the rods and their heaters hung from a suspension of wires and counterweights, each heavy brass assembly held clear of the scalp while its heat was delivered to the wound hair. The whole array, when a full head was dressed, resembled a small brass chandelier suspended above the client — dozens of dangling rods, wires, and weights, each conducting its own current. The alkaline dressing Nessler kept secret, but it was, by the best accounts, a borax-based paste — the same borax that had served the Victorian dressing-room as a setting agent, now pressed into a far more demanding role. Applied under heat, it began to reshape the disulfide bonds of the keratin. It was the first time chemistry and heat had been made to act on the hair together, at sustained intensity, for hours.

The genius of the machine was not any single part but their combination: a spiral rod that carried the curl's shape, an alkali that reshaped the keratin, and an electric current that held the heat long enough for the reshape to take. Take any one away and the curl washed out, as it had for thirty centuries.

The client's ordeal

The experience of receiving a Nessler wave was, by every surviving account, an ordeal. The treatment took hours — the often-cited figure of roughly six hours in the chair is consistent with contemporary reports of a full head dressed rod by rod. (Some accounts give longer, up to twelve; the duration varied with the hair's length and density, and no single number should be treated as fixed.) Throughout, the client sat motionless beneath a frame of hot brass and live wire, unable to move her head for fear of disturbing the rods, while each heater did its slow work.

The danger was real and familiar. Nessler's earliest experiments, conducted in Paris on Katharina Laible before the machine was refined, had raised blisters on her scalp, and the first attempts had failed outright — the heat scorched the hair off before the curl could set. The successful wave came only on the third attempt, after prolonged washing of the rods. Even in the mature London practice, the countercurrent of heat rising from each brass rod toward the scalp meant that burns remained an occupational hazard, and the long exposure to the alkaline paste left the scalp irritated for days. A Nessler wave was not a comfortable service. It was, however, a lasting one — and that single fact outweighed every other consideration for the women who could afford it.

London, c.1906–1914

A full permanent wave takes the greater part of a day. The client sits beneath an overhead array of brass rods, counterweights, and live electrical cords, each rod wound with a spiral of her own hair and clamped by its own heater. The heat is intense, the alkali irritates the scalp, and the countercurrent of rising warmth keeps the skin close to the burn threshold throughout. She does not move for hours. When the rods come down at last and the hair is washed, the curl is still there — and it is still there after the next wash, and the next.

What changed

Why, then, does 1906 deserve the weight it carries? Not because Nessler invented the curl, the iron, or the setting paste — all three were older than recorded Europe. Nor because his machine was safe, fast, or cheap; it was none of these. The year matters for a single, narrow, epochal reason: after Nessler's treatment, the curl survived washing. The disulfide bonds of the keratin had been rearranged under sustained heat and alkali, and the new arrangement held its shape in water. The wave was, in the precise chemical sense, permanent.

This was the break that three millennia of heat and gum arabic had failed to achieve. Every curl before Nessler — the Egyptian tongs, the Roman calamistrum, the powdered wig, the Victorian iron, Grateau's Marcel wave — had been a temporary visitor, dissolved by the next wash. Nessler's was the first that did not dissolve. A woman who had paid for a Marcel wave two or three times a week could, in principle, pay once for a Nessler wave and wear it for months.

Before Nessler, every curl in history was borrowed time. After him, for the first time, it was time kept.

The limitation that sets up the rest of the story

And yet Nessler's method carried within it the very limitation that would, within twenty years, render it obsolete. The spiral wind demanded long hair. Each rod had to run through the curl along its length, which meant the hair had to be long enough to be wound spirally from the scalp outward — the dressed Edwardian hair of the first years of the century. Nessler had built his machine, in good faith, for the hair fashionable women actually wore in 1906.

He had not built it for the bob. When, after the First World War, women across Europe and America cut their hair short — blunt, boyish, to the jawline or above — the spiral wind became, overnight, impossible: there was not enough length to wind along a rod. The most fashionable hairstyle of the new era was, by a cruel irony, the one the machine that had invented the permanent wave could not serve. The demand for permanence did not vanish; it exploded, as millions of bobbed women sought the wave that the bob itself made unreachable by Nessler's method.

The resolution of that contradiction is the subject of the chapters that follow. The machine age of the 1910s and 1920s would carry Nessler's basic principle — heat plus alkali, applied rod by rod — toward safety and speed, through the work of Suter, Calvete, Rambaud, and Bishinger. But none of the spiral machines, however refined, could solve the bob. That required a different idea: a winding that began not at the scalp but at the ends of the hair, wrapping the short lengths inward toward the head — the croquignole, or flat, winding that Josef Mayer would present in 1924. Nessler had opened the age of the lasting curl. The bob would force the age of the modern perm.
