L’Oréal Professionnel professional hair products

L’Oréal Professionnel Paris is part of L’Oréal’s Professional Products portfolio and focuses on professional hair care, hair color, lightening and styling. The brand has been connected with the professional hairdressing industry since 1909 and develops product systems for salon services as well as routines designed to maintain professional hair results at home.

The portfolio includes products for a broad range of hair and scalp needs, from everyday shampoos and conditioners to intensive masks, serums, oils, heat-protection products and leave-in care. Dedicated ranges address concerns such as damaged or chemically treated hair, color maintenance, curl care, smoothing and scalp care.

Hair care for specific concerns

Damaged and weakened hair

Absolut Repair Molecular and other restorative L’Oréal Professionnel ranges are designed for damaged-hair routines. Depending on the range and individual product, a routine may include shampoo, rinse-out care, a mask, serum or oil. This makes it possible to select products according to the condition of the hair and preferred treatment format.

Care for colored hair

Vitamino Color Spectrum is designed for color-treated hair. Its portfolio includes shampoos, conditioning care, masks and serums, together with tone-neutralizing shampoos developed for selected unwanted undertones. These products can form part of a maintenance routine following professional hair-color services.

Metal Detox and Glicoamine

Metal Detox was developed around the issue of metal particles such as copper entering the hair fiber through water. Selected Metal Detox formulas use Glicoamine. The range includes a professional pre-treatment, shampoo, mask, protective leave-in cream and oil, creating a system particularly relevant before and after color, balayage and lightening services.

Curls and scalp care

Curl Expression provides care and styling options for curly and coily hair, while Scalp Advanced focuses on specific scalp-care needs. When choosing a product, consider the individual hair or scalp concern as well as the usage instructions for the specific formula.

Professional hair color and lightening

L’Oréal Professionnel offers an extensive professional hair-color portfolio that includes permanent color, demi-permanent or tone-on-tone color, developers and lightening products. iNOA is an ammonia-free permanent hair-color range using patented Oil Delivery System, or ODS, technology. Majirel provides professional permanent color, while Dia Color is positioned in the demi-permanent color category.

The Blond Studio range covers professional lightening and techniques including highlights and balayage. Hair-color, developer and lightening products should always be selected and used according to the manufacturer’s instructions and any professional-use requirements.

Tecni.Art professional styling

Tecni.Art includes a wide range of styling textures and hold formats, including hairsprays, mousses, gels and gel-creams, pastes, powders and creams. Products can be selected according to the required effect, such as volume, texture, curl definition, smoothness, hold or preparation before blow-drying.

How to choose L’Oréal Professionnel products

Start with the main objective: damage care, color maintenance, smoothing, curl definition, scalp care or styling. Then choose the range designed for that concern and combine complementary products where appropriate.

• For damaged hair, explore restorative and strengthening hair-care ranges.
• For color-treated hair, choose dedicated color-care shampoos, masks and serums.
• For routines around color or lightening services, consider the Metal Detox system.
• For curls and coils, explore Curl Expression care and styling.
• For styling, select a Tecni.Art product according to the desired texture, hold and finish.

The breadth of L’Oréal Professionnel’s portfolio makes it possible to connect professional salon services with targeted home care while choosing products according to hair type, condition and the desired result.
