L’Oréal Pro Serie Expert Metal Detox Pre Shampoo

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

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

If you have colour, balayage, or bleaching, 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% Glycofiller penetrates deep 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 fade after colouring.

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

The 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 with a light, soft, and deeply nourished feel.

It is the ideal product for those who want to protect their colour, prevent breakage, and maintain a healthy, shiny appearance 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 home. Transform your hair care routine into a true professional ritual, with visible results from the very first use.
