L'Oréal Professionnel Metal Detox Hair Mask 250ml — Colour Protection & Breakage Prevention for Colour-Treated Hair

Protect your colour. Strengthen your hair. Neutralise hard water damage.

Hard water deposits copper and other metal particles directly into your hair fibres with every wash. Over time, these invisible metals weaken the hair structure, dull your colour, and cause breakage — without you ever knowing the cause.

The L'Oréal Professionnel Metal Detox Hair Mask targets this problem at the source. Powered by Glicoamine, a patented molecule small enough to penetrate deep inside the hair fibre, it tracks and neutralises metal particles from within — not just on the surface. The result is stronger, smoother hair and colour that stays vibrant wash after wash.

Key Benefits

• Up to 87% less breakage (clinically tested)
• 2× shinier hair after use
• Protects colour from metal-induced fading and colour shift
• Instantly moisturises, smooths, and softens lengths
• Suitable for all hair types — colour-treated, bleached, balayage, or virgin hair
• Creamy, easy-to-rinse formula with a luxurious citrus and musky wood fragrance

How to Use

1. After shampooing with Metal Detox Anti-Metal Cleansing Shampoo, apply the mask to towel-dried lengths.
2. Leave on for 1–3 minutes.
3. Rinse thoroughly.
4. Use regularly for sustained protection between colour services.

For best results, use as part of the full Metal Detox routine — in-salon pre-treatment combined with at-home care delivers the full clinically tested results.
