L'Oréal Professionnel Serie Expert Metal Detox Pré-Shampoing Pre-shampoo for sensitized and brittle hair 250 ml

SCIENTIFIC DISCOVERY
Wash after wash, the metal in the water penetrates deep into the hair shaft. This is one of the main causes of hair breakage. But did you know that porous hair is at a higher risk of breakage because it absorbs twice as much water—and therefore twice as much metal?

Daily stressors such as chemical treatments, heat styling tools, or UV exposure increase the number of micro-breaks on the hair’s surface and create cavities in the cortex. This makes the hair even more porous, causing it to absorb excessive amounts of water and, consequently, metal, leading to a higher risk of hair breakage.

SCIENTIFIC INNOVATION
Anti-porosity technology* to treat hair when it is most vulnerable to water: before shampooing. It is formulated with 2% Glicofiller, an active ingredient that works both on the surface and within the cortex to prevent excessive absorption of water containing metals:

- On the surface: it coats the hair shaft and fills in 1 million micro-breaks in just 1 minute*.
- Inside the hair shaft: it penetrates deeply and replenishes the hair all the way to the cortex.

This new pre-shampoo is part of the Metal Detox line, a comprehensive anti-metal regimen designed to prevent breakage and color fading.

1 MILLION MICROSCRATCHES IN JUST 1 MINUTE.
The fiber is less porous*, 25 times stronger, and breaks 96% less often after a single use**.
Hair is deeply hydrated: 72 hours of hydration, softness, and suppleness**.
Instantly plumped up, hair feels nourished and looks visibly healthier.

INSTANT DETANGLING
Instant and effective detangling for all hair types.
Prepares the hair before washing and makes it easier to use the shampoo.
