L’Oréal Pro Serie Expert Metal Detox Pre Shampoo

L’Oréal Professionnel Metal Detox Pre-Shampoo – The Essential Base for Strong, Long-Lasting Colour

Hair care starts before shampoo. L’Oréal Professionnel's Metal Detox Pre-Shampoo is the first step for a truly effective hair care routine for coloured or bleached hair. Developed with professional technology, this treatment works on the internal structure of the hair fibre, filling micro-fissures and strengthening strands from the very first use.

If you have colour, balayage or bleached hair, this is the treatment that will transform your hair: less breakage, vibrant colour and anti-porosity protection that prepares the hair for a safe wash, without compromising colour longevity.

The concentrated formula with 2% Glicofiller penetrates deeply into the hair, filling porous areas and restoring its uniformity. This simple step before shampoo prevents excessive water absorption - one of the main causes of breakage and colour loss after colouring.

With just one application, you will feel your hair softer, denser and more resilient. Up to 99% less breakage, 1 year of damage repaired in just one night, and visibly more reliable and long-lasting colour throughout washes.

Metal Detox Pre-Shampoo is not just a technical treatment: it's a gesture of care and regeneration. Its rich texture glides easily onto wet hair, facilitating detangling and leaving strands feeling light, soft and deeply nourished.

It's the ideal product for those who want to protect their colour, prevent breakage and maintain a healthy, shiny look every day.

Created in collaboration with experts, this pre-shampoo is one of the best-kept secrets of salons. And now, it's available for you to use in the comfort of your own home. Transform your hair care routine into a true professional ritual, with visible results from the very first use.
