The Secret History Of Hairspray: 7 Shocking Facts About Its Invention And Evolution

• minute read

The seemingly simple can of hairspray is a secret marvel of wartime technology and chemical engineering. While many people assume the product is a staple of the 1950s beehive era, the true invention of the first commercial aerosol hair lacquer actually dates back to the late 1940s, directly leveraging a crucial innovation designed for U.S. soldiers during World War II. Its journey from a sticky, shellac-based formula to the modern, flexible hold sprays of today is a fascinating timeline of consumer demand, environmental awakening, and scientific advancement.

As of December 23, 2025, the history of hairspray continues to be defined by its chemical composition, with manufacturers constantly reformulating products to comply with ever-stricter environmental regulations, particularly concerning Volatile Organic Compounds (VOCs). To understand the modern product, you must first look back at the military-grade technology that made the aerosol can possible and the post-war beauty boom that turned a canister of insecticide into a global cosmetic necessity.

The Pre-History: What Held Hair Before the Can?

The desire for a perfectly set hairstyle is ancient, but the methods were often cumbersome and messy. Before the invention of modern hairspray, people relied on a variety of natural and sometimes sticky substances to achieve hold. These pre-1940s hair setting solutions were a far cry from the convenience of a spray can.

  • Natural Resins and Gums: Ancient Egyptians, for example, used beeswax and natural resins to keep their elaborate styles in place. In later eras, ingredients like gum arabic (derived from the Acacia tree) and pine resin were mixed into setting lotions to provide a stiff hold.
  • Shellac: The early commercial hair lacquers of the late 1940s, before the term "hairspray" was coined, primarily used shellac, a natural resin secreted by the female lac bug. While effective, shellac-based products often left hair feeling stiff, brittle, and difficult to brush out, leading to the infamous "helmet hair" look.
  • Wet Sets: The most common method of styling in the 1930s and early 1940s was the wet set. Hair was rolled onto pin curls or rollers while wet, then saturated with a liquid setting lotion (often containing shellac or similar resins) and left to dry, sometimes for hours under a bonnet hair dryer.

The inconvenience of these methods created a massive market opportunity for a quick-drying, easy-to-apply product that could deliver instant, lasting hold. This opportunity was finally unlocked by a military invention.

1943–1950: The World War II Innovation That Created Hairspray

The true genesis of hairspray has less to do with cosmetics and everything to do with protecting soldiers from tropical diseases.

The Invention of the "Bug Bomb"

The pressurized aerosol can was not invented for beauty. It was a crucial piece of equipment developed during World War II to combat insect-borne diseases like malaria, which were devastating U.S. troops in the Pacific.

  • 1941: Agricultural chemists Lyle Goodhue and William Sullivan of the U.S. Department of Agriculture (USDA) developed the first practical, portable aerosol dispenser.
  • The Technology: This invention was a small, pressurized can that used a liquefied gas propellant (like Freon) to spray an insecticide. It was immediately nicknamed the "bug bomb" or "aerosol bomb."
  • Post-War Surplus: After the war ended in 1945, the patents for the aerosol can became available for civilian use, and the manufacturing technology was already established. Companies quickly realized this delivery system could be used for a wide range of consumer products—including hair lacquer.

The First Commercial Hairspray

The transition from a military insecticide dispenser to a beauty product happened rapidly in the late 1940s:

1948: The First Aerosol Hair Lacquer

In 1948, the first aerosol hair lacquer was bottled by Chase Products, marking the actual moment the product entered the commercial beauty market.

1950: The Coining of "Hairspray"

The product only truly became "hairspray" in 1950 when the famous beauty company Helene Curtis launched its own version. They were the first to use the generic, now-ubiquitous term "hairspray" for their new aerosol product, which they named Spray Net.

The combination of the convenient aerosol can and the post-war fashion for elaborate, structured hairstyles (like the bouffant and the beehive) led to a massive boom in popularity. By 1955, Helene Curtis’s *Spray Net* and its competitor, Aqua Net, were best-selling products globally, solidifying the hairspray can as a counter-culture icon.

The Environmental Evolution: From CFCs to VOC Compliance

The hairspray industry experienced its most significant upheaval not from a fashion trend, but from a scientific and environmental crisis involving its key ingredients.

The CFC Crisis and the Montreal Protocol

For decades, the aerosol cans relied on Chlorofluorocarbons (CFCs), such as Freon, as the propellant. CFCs were highly effective but were eventually discovered to be severely depleting the Earth's ozone layer.

  • 1978–1979 Ban: The United States took the lead, banning the use of CFCs in non-essential aerosol products, including hairspray, starting in 1978 and completing the phase-out by April 1979.
  • Global Action: The global community followed suit with the Montreal Protocol in 1987, an international treaty designed to phase out the production of numerous substances responsible for ozone depletion.
  • The Replacement: Manufacturers quickly reformulated, replacing CFCs with safer propellants like hydrocarbons and compressed gases. The film-forming agents also evolved, moving from sticky shellac to synthetic polymers like PVM/MA Copolymer (Polyvinyl Methyl Ether/Maleic Anhydride Copolymer), which offered a more flexible, brushable hold.

The Modern Challenge: Volatile Organic Compounds (VOCs)

The environmental scrutiny did not end with CFCs. Today, the focus is on Volatile Organic Compounds (VOCs), which are common solvents in hairspray that contribute to smog and air pollution.

  • CARB Regulations: The most stringent regulations often originate from the California Air Resources Board (CARB), which sets the standard for the rest of the country and the world.
  • The 55% Limit: CARB regulations lowered the amount of acceptable VOCs in hairspray from an initial 80% to a strict limit of 55% VOC content, which became effective in 2005.
  • Reformulation: This mandate required a complete reformulation of many classic hairspray products, forcing chemists to create new, high-performance, VOC-compliant sprays that use more water and less solvent while maintaining the expected level of hold and humidity resistance.

The invention of hairspray, therefore, is not a single date but a series of groundbreaking innovations: the 1943 aerosol can, the 1948 commercial release, the 1950 naming by Helene Curtis, and the continuous, environmentally-driven reformulations of the 1970s and 2000s. It remains a testament to how military necessity and environmental consciousness can drive rapid change in the consumer product industry.
