All you need to know about Metal Detox Mask.

  • 1. What is Metal Detox Professional Mask by L’Oréal Professionnel?

    Metal Detox Professional Mask is a professional hair mask that intensely nourishes the fiber while helping protect hair from metal particles responsible for hair breakage, dryness and color shift.

  • 2. Why is this mask ideal after color and bleach services?

    After repetitive color and bleach services, hair is more porous and fragile; this mask helps protect the fiber from metal-related damage, reducing the risk of hair breakage and helping maintain vibrant, even color.

  • 3. How does Metal Detox mask help with hair breakage?

    The formula, enriched with Glicoamine, helps neutralize metal inside the fiber and protects against new deposits, so hair feels stronger, more resilient and less prone to hair breakage, even on sensitized, bleached hair.

  • 4. How do I use Metal Detox mask in my routine?

    After washing with Metal Detox shampoo, apply the mask on towel-dried hair, leave for 1–2 minutes or 15 minutes for a deeper care then rinse thoroughly; use it as your go-to hair mask after color, bleach or any service where hair is exposed to water.

  • 5. How often should I apply this mask?

    You can use it after every shampoo, especially if your hair is color-treated, bleached or prone to hair breakage and dryness, to maintain reinforced, hydrated and shiny hair over time.

  • 6. Is it suitable for dry and very dry hair?

    Yes, it delivers intense care for dry and very dry hair, leaving lengths and ends feeling nourished, smoother and easier to detangle without weighing the hair down. The lightweight creamy texture delivers up to 100 hours of intense hydration and +96% softness without weighing hair down, for a smoother, more manageable feel.

  • 7. Can I use this hair mask on bleached or highlighted hair?

    Absolutely; this hair mask is particularly recommended for bleached hair, helping to limit breakage, dryness and roughness often observed after repetitive bleach.

  • 8.  Is Metal Detox mask suitable for very damaged hair?

    Yes, this professional hair mask is ideal for damaged hair weakened by repeated color, bleach and heat styling, helping to reduce visible signs of damage such as hair breakage, roughness and dullness while leaving the fiber feeling stronger, smoother and more supple.

  • 9. Is Metal Detox mask suitable for natural, non-colored hair?

    Yes, even natural hair can accumulate metal from water, which can lead to dryness and breakage; this mask helps protect the fiber, keeping hair softer, shinier and easier to style.

  • 10. Can I combine it with other Metal Detox products?

    For the best anti-metal and anti–hair breakage routine, use the mask with Metal Detox shampoo and the leave-in protection products, especially after repeated color or bleach services.
