From ancient fats to modern polymers: the chemistry of hair control
In short: The substances we use to sculpt our hair have evolved from animal fats and wax to sophisticated chemical polymers. While modern sprays and gels offer precise textures, they trace back to ancient techniques used to preserve identity in the afterlife and manage the very first chemical relaxers of the 20th century.
The history of hair styling is a progression of material science. Ancient Egyptians used a fatty substance—now recognized as hair gel—to maintain the individuality of the deceased during the embalming process. Similarly, the Gauls developed a waxy, soap-like substance to style hair, a substance that would later transition into a cleaning agent. By the 11th century, 'bear grease' made from bear fat and marrow was marketed as a remedy for baldness, while 18th-century innovations like Rowland's Macassar Oil introduced oils as primary conditioners for European grooming.
The industrial era brought rapid diversification. In 1900, Édouard Pinaud introduced Brilliantine, a petroleum-derived product, while 1909 saw the debut of the first American hair relaxer, created by tailor Garrett Augustus Morgan. The mid-20th century saw the rise of hair spray, first packaged by Chase Products in 1948. This innovation utilized polymers to stiffen hair without snapping the strands. Early versions used chlorofluorocarbons (CFCs) as solvents, which were later replaced by alcohols and hydrocarbons to protect the stratospheric ozone.
Today, the market is segmented by desired texture and hold. Hair wax provides a pliable finish, whereas hair gel offers a stiffer, more defined structure. Mousse provides volume without buildup, and pomades—often oil-based—create slick, tight styles that require deep-cleansing to remove. Modern 'volumizers' use humectants to pull moisture into the hair, swelling the strand to create the illusion of thickness. While most products are safe, the chemical interplay of solvents and waxes can occasionally strip natural oils, leading to dryness or buildup.
