L'Oréal Professionnel

L'Oréal Professionnel is a French professional haircare and hair-colour brand headquartered in Paris and operating within the Professional Products Division of L'Oréal Group [8]. It traces its origins to 1909, when the chemist Eugène Schueller began formulating his own hair dyes and selling them directly to Parisian hairdressers — a salon-distribution model that became the founding business of the wider L'Oréal company [9]. The brand develops hair colour, care, styling products and professional tools sold through salons, and according to the company it works with independent and in-salon hairstylists across 66 countries.

Today it presents itself as the professional or salon-facing arm of L'Oréal Group, distinct from the consumer-facing L'Oréal Paris. Its catalogue is built around professional colour lines such as iNOA, Majirel and Blond Studio, alongside care collections including Métal Detox and Absolut Repair.

The brand's roots lie with Eugène Schueller (1881–1957), a French chemist who developed an early hair-colour formula in 1907 and, in 1909, registered a company in Paris under the name Société Française de Teintures Inoffensives pour Cheveux — the "French Company of Inoffensive Hair Dyes" — which later became L'Oréal [9]. Schueller manufactured the dyes himself and sold them to working hairdressers, and L'Oréal Professionnel treats this salon channel as its own founding heritage, since the professional trade was the original business model.

The company's US site dates the brand only vaguely, describing it as founded "more than 110 years ago" [2], while its UK site, Wikipedia and Britannica give the specific year 1909 [7][8]. The brand says it began in a "modest Paris apartment" where Schueller created what it calls the world's first harmless hair dye.

From the start the brand tied itself to the hairdressing profession. It established an early hairdressing school in 1938 and, according to its own account, was behind a series of technical firsts in salon work, including the first cold perm and the first skin-allergy tests for hair colour.

In 1954 the company founded the Style & Colour Trophy, a hairdressing competition that began on Tottenham Court Road in London and which the organisers describe as the longest-running live hairdressing competition in the world; by 2026 it reached its 70th edition [12]. Later milestones reflect a shift toward devices and patented chemistry: the Steampod professional steam styler launched in 2012 through a partnership with Rowenta, part of Groupe SEB, rolling out in 45 countries [14], and the Métal Detox range followed in 2021.

L'Oréal Professionnel is the original founding business of L'Oréal Group and now sits inside the group's Professional Products Division [8]. That division also houses sister brands created or acquired by the parent company over the decades, among them Kérastase, created by L'Oréal in 1964, and Redken, acquired in 1993 [8]. The group reports that, as of 2024, it is the world's largest cosmetics company by revenue. L'Oréal Professionnel does not have a separate corporate Wikipedia entry; it is documented as part of the parent group's history.

The company frames its purpose as developing the professional hair industry, a phrase it presents as its founding mission. It describes its character through a "pioneer spirit" and a "passion for science," and positions the brand as "born in tech and science," with a stated focus on innovation, technology and safety for stylists and their clients.

Positioning is built around the salon professional rather than the retail shopper. The brand emphasises education programmes for hairdressers and runs a mental-health initiative for salon workers called Head Up, described by the company as created by people who understand salon life.

The portfolio centres on professional hair colour and care. Its colour ranges include iNOA, an ammonia-free permanent colour whose name the brand glosses as "Innovation, NO Ammonia" and which uses what it calls an Oil Delivery System; the permanent crème colour Majirel; the demi-permanent Dia Color and Dia Light; and the Blond Studio lightening system.

On the care side, Métal Detox launched in 2021 around a patented synthetic molecule called Glicoamine, developed with the University of Ioannina in Greece, which the brand says neutralises metal inside the hair fibre; the company claims the range delivers 87% less hair breakage [13]. The Absolut Repair Molecular line is described by the brand as protected by six patents. Beyond formulas, the brand sells professional tools, including the Steampod steam styler developed with Rowenta [14] and, more recently, the AirLight Pro hairdryer.

The company has set environmental targets across three areas: water, packaging and energy. According to its commitments, it aims for all of its factories to use closed-loop "waterloop" technology to treat and reuse industrial water by 2030, and to reduce the water needed to rinse products by 25%. On packaging it states goals including a 20% reduction per gram of formula against a 2019 baseline and making all plastic packaging reusable, recyclable or compostable. The brand also reports that 90% of its products are made in facilities running on renewable energy, with a stated goal of carbon-neutral owned and operated sites.

The founder's wartime record has drawn scrutiny. In 2017, reports surfaced that Eugène Schueller had been a vocal supporter of the Nazi regime in occupied France during the Second World War [10].

As part of L'Oréal Group, the brand is also tied to wider corporate controversies. The group remains on PETA's "do test" list because it sells cosmetics in markets such as China, where animal testing of certain products can be legally required; as a result L'Oréal Professionnel is not certified cruelty-free under PETA's programme [19]. The parent group has separately faced litigation in the United States over the safety of chemical hair-relaxer products, claims that primarily target consumer brands but to which the wider group has noted exposure [10].

L'Oréal Professionnel is active. It functions as a flagship brand of L'Oréal Group's Professional Products Division, with distribution through salon channels in 66 countries. Recent product launches — including the AirLight Pro tool, Keratin Alpha Sleek and the Absolut Repair Molecular Bi-Phase Oil — feature on its current sites, and its Colour Trophy competition continued into its 70th-anniversary year.
