About L’Oréal Professionnel
L’Oréal Professionnel Paris is a professional hair brand whose origins date to Paris in 1909. Its history is linked to chemist Eugène Schueller, who developed hair colour and built the business around the needs of professional hairdressers. That relationship with salon professionals remains central to the brand today.
The portfolio spans professional haircare, colouring and styling products for salons, hairdressers and customers who want to maintain professional hair results at home.
What is L’Oréal Professionnel known for?
Science, technical expertise and innovation have played a central role throughout the brand’s history. Its professional innovations range from early developments in hair colour to contemporary systems such as iNOA and Metal Detox, alongside advanced care and styling ranges.
Metal Detox uses Glicoamine technology developed to neutralise metal particles inside the hair fibre and reduce the unwanted effects associated with metals during colour, balayage and lightening services. Other ranges address needs including damaged or chemically treated hair, colour maintenance, blonde hair, curls and scalp care.
L’Oréal Professionnel products
The range includes professional shampoos, conditioners, masks, serums, oils and leave-in care. The current SalonLine assortment can be explored on the L’Oréal Professionnel brand page.
Serie Expert haircare
Serie Expert brings together targeted routines for different hair needs. Metal Detox focuses on the effects of metal particles in hair, while other ranges provide specialised routines for damaged, coloured, blonde, curly or scalp-focused haircare.
Professional colour and styling
The professional colour portfolio includes permanent and tone-on-tone colour systems, lightening products and related salon products. SalonLine also offers a dedicated category for permanent hair colours. For hold, texture, shape, volume and finish, customers can also explore professional hair styling products.
Who are L’Oréal Professionnel products for?
The range is relevant to professional hairstylists and salons as well as customers looking for targeted, salon-led haircare at home. Depending on the individual range, routines can be selected for damaged, coloured, bleached, curly or unruly hair, scalp needs, professional colour services and styling.
