L’Oréal Professionnel: hair care for coloured and long hair

L’Oréal Professionnel is a hair care brand that has supported hairstylists since 1909, and its products suit coloured, bleached and long hair. Our selection has two Serie Expert treatments: the Metal Detox oil for coloured hair and the Pro Longer cream for long hair. Read on to find out how the brand began, what Serie Expert offers and how these two products fit into your everyday hair routine.

A story that began in a Paris apartment

In 1909 a young chemist named Eugène Schueller invented the world’s first harmless hair dye. The story began in a modest Paris apartment, and the colour quickly became popular with hairstylists across Europe. More than 110 years have passed since hair colour was invented, and L’Oréal Professionnel has supported hairstylists the whole time. The brand’s founding mission is to develop the craft of hairdressing.

Several pioneering innovations are linked to the brand’s history: the first cold perm, the first skin allergy tests, the level of depth scale and tone-on-tone colour. Today the brand works with hairstylists in 66 countries. Initiatives support the hairstylist community too: the Style & Colour Trophy is the longest-running hair competition in the world and has been held since 1954. The Head Up initiative helps hairstylists look after their mental health.

Science and technology at the styling chair

The brand pushes the boundaries of science and technology and focuses on innovation and safety for hairstylists and their clients. Its work includes the iNOA [iD] colour diagnosis tool, the Absolut Repair Molecular range protected by six patents and the fourth-generation SteamPod 4 steam styler.

Serie Expert: care that works together

Serie Expert is the L’Oréal Professionnel care collection that gives its name to the products in our selection. Each line focuses on one hair concern: one keeps coloured hair vibrant, another rebuilds damaged structure, a third looks after the ends of long hair. The lines can be combined: a shampoo, a conditioner or mask and finally a leave-in treatment make a whole, so the routine stays clear.

Metal Detox: oil for coloured and bleached hair

Metal Detox is a line whose aim is to help remove metal deposits from hair. Our selection has a hair oil in a 50 ml size. It is a concentrated, lightweight oil serum that does not weigh the hair down. Its formula contains Glicoamine, which helps to prevent and remove metal particles.

The oil suits all hair types and textures, including coloured, damaged and bleached hair. It hydrates, locks in moisture and shine and leaves hair with a smooth, cared-for look. It helps to improve hair texture, protects against humidity and heat and gives heat protection up to 230 °C, so it fits before blow-drying and straightening. The small size fits into a handbag and is easy to take along when the shine needs a refresh during the day.

When colour, bleach or treatments have left a mark, a light but effective oil is a comfortable way to give hair back a smooth, glossy look. The oil is part of the finish and needs no special skill.

Pro Longer: the ends of long hair

Pro Longer is a line for long hair with thin ends. It is designed to renew lengths and ends. Our selection has a leave-in cream in a 150 ml size, a treatment that is not rinsed out.

The cream renews lengths and ends, protects against frizz and strengthens the hair fibre from root to tip, so hair is less damaged. Heat protection reaches up to 230 °C. The formula contains patented Filler-A100 technology and an amino acid. Using it is simple: apply the cream to clean, towel-dried hair, do not rinse, then blow-dry and straighten as usual.

The longer the hair, the longer its ends have lived with the blow dryer, the comb, the hair tie and the sun. The Pro Longer cream is made for that part and helps keep the length healthy and tidy.

Which hair each product suits

The Metal Detox oil is a good choice when hair has been through colouring or bleaching and you want care that does not weigh it down. The concentrated oil serum works well as a finishing step. Applied before blow-drying, it gives hydration, shine and heat protection in one go, and protection from humidity on damp days.

The Pro Longer cream is a 10-in-1 treatment for hair that is long but has thinned at the ends. It needs no rinsing, so it fits even a rushed morning: apply it to towel-dried hair and style as usual. If you are growing your hair, it lets you look after the lengths from root to tip after every wash.

How Metal Detox and Pro Longer work together

The two products complement each other. The oil is a finish that adds shine and heat protection; the cream is a treatment that looks after the lengths and ends of long hair. After washing, first apply the cream to towel-dried hair, then, if you like, a little oil through the lengths, and dry your hair. That way hair gets care, protection and shine without the routine growing long.

The pair also makes a thoughtful gift for someone who loves long or coloured hair. A small oil and a larger cream form a compact care set that you can give for a new haircut, a blonde shade or a colour change. A gift for hair is personal and useful, because hair needs care every day.

A glossy look every day

Hair is part of how we feel about ourselves. When the ends are in good order and the lengths are shiny, the hairstyle is easier and the morning is faster. That is why hair care is worth turning into a habit rather than a special occasion. A small care step after washing takes a couple of minutes but gives a result you see in the mirror every day.

Coloured and bleached hair look their best when they are well looked after. That makes the care that follows as important as the colour itself. Metal Detox is a choice for those who want colour and shine to last, and Pro Longer for those who are growing their hair long and want to keep the ends lively.

With long hair, care begins at the ends. Drying for styling and straightening are familiar moments, and a treatment cream brings care into them. Combined with a light oil, it gives hair that is soft, tidy and ready for a loose style or a ponytail.

Tips for building a routine

Start simple: one care product that you use regularly is better than ten products used rarely. First choose the one that matches your hair’s biggest need and add a second only when the first has become a habit. With long hair, for example, the first step can be the Pro Longer cream and the second the Metal Detox oil for shine.

Notice how your hair behaves: when it is softest, when it is shiniest and when it needs more care. These observations help you decide when to add treatment. That is how a routine forms that suits you, not an average hair type.

How to choose the right product

Start from the state of your hair. If it is coloured or bleached and you want shine and heat protection, choose the Metal Detox oil. If your hair is long with thin ends, choose the Pro Longer cream. To expand the routine, browse the whole range of hair care. After washing, hair conditioners are a good fit, and for deeper care there are hair masks.

Good hair care rests on regularity. Three steps are enough: gentle washing, care and finish. When the steps are chosen with care, the routine stays simple. Hair responds with a beauty and shine that last from day to day.
