In the early 20th century, Eugène Paul Louis Schueller (1881–1957), a French chemist, developed a hair dye formula called l'Auréale.[7] Schueller formulated and manufactured his own products, which he sold to Parisian hairdressers.[8][9] On 31 July 1909, Schueller registered his company,[10] the Société Française de Teintures Inoffensives pour Cheveux (Safe Hair Dye Company of France), which eventually became L'Oréal. In 1920, the company employed three chemists; the number of employees continued to grow, with 100 by 1950, and 1,000 by 1984; in 2021, there was an estimated total of 85,252 worldwide.[11]
