L'Oréal Professionnel Metal Detox is a professional treatment system that targets damaging metal particles—especially copper from hard water—deep inside your hair. Using patented Glicoamine technology, it neutralises metals that cause breakage and unpredictable colour results, leaving hair up to 87% stronger and visibly smoother. Whether you're a regular at our East Grinstead salon for balayage, highlights or full colour, Metal Detox ensures your service delivers the most reliable, even and lasting results possible.
More information
What Happens During Your Treatment
Metal Detox fits seamlessly into your colour or lightening appointment as a three-step protocol:
- Pre-treatment spray – Applied to dry hair before your colour service and combed through lengths; it neutralises metals in the cortex while your stylist mixes your colour, adding no extra processing time
- Sulfate-free cleansing cream – After your colour is rinsed, this gentle shampoo removes neutralised metals and cleanses without stripping
- Targeted mask or conditioner – Chosen by your stylist based on your hair type (lighter conditioner for fine hair, richer mask for thicker or sensitised hair), left for a few minutes to smooth, nourish and protect against new deposits
The entire process happens within your usual colour appointment time—Rebekah, Marie, Jade and Katie will tailor each step to your hair's needs.
Who Benefits Most from Metal Detox
This treatment is ideal if you:
- Colour, balayage or lighten regularly, especially if you're blonde or have porous hair
- Live in a hard-water area like East Grinstead, where copper and minerals accumulate in hair over time
- Experience breakage, dryness or patchy colour that doesn't take evenly
- Want to protect your hair from the inside out and maintain vibrant, reliable colour between visits
Metal Detox suits all hair types and textures—from fine to thick—and works alongside any professional colour or lightener brand we use in the salon.
Results You Can Expect
With Metal Detox integrated into your service, you'll notice:
- Up to 87% less breakage during and after lightening or colouring
- 100% more reliable colour results—fewer unexpected tones or patchy areas caused by metal reactions
- Hair that feels stronger, smoother and more nourished, with improved shine and easier detangling
- Longer-lasting colour clarity, especially in hard-water conditions
Results are optimised when you continue care at home with Metal Detox shampoo and mask between appointments, keeping metal buildup low and your colour fresh.
Aftercare and Maintenance
To maintain the benefits of your in-salon treatment:
- Use Metal Detox shampoo at home as your first cleansing step to gently remove new metal deposits
- Follow with the Metal Detox mask on towel-dried hair for about one minute, then rinse to protect and nourish
- Consider Metal Detox leave-in oil or cream to further guard against metal entry and reduce daily breakage
- Book Metal Detox with every colour service (typically every 8 weeks) for ongoing protection and the best colour outcomes
Your stylist will recommend the right home-care routine based on your hair type and how often you visit the salon.
Frequently Asked Questions
What is L'Oréal Metal Detox and how does it work?
L'Oréal Metal Detox is a professional treatment system that uses patented Glicoamine technology to neutralise and remove metal particles—especially copper—from inside your hair. These metals accumulate from hard water and the environment, causing breakage and unpredictable colour results. The system traps metals before, during and after your colour or lightening service to protect hair and improve outcomes.
How much does Metal Detox cost and how long does it take?
Metal Detox is £15 as an add-on to your colour, balayage or lightening service. It fits seamlessly into your appointment with no extra processing time—the pre-treatment is applied while your colour is mixed, and the shampoo and mask steps happen during your usual back-wash routine.
Who should have Metal Detox treatment?
Metal Detox is ideal if you colour, balayage or lighten your hair regularly, live in a hard-water area like East Grinstead, or experience breakage, dryness or patchy colour. It suits all hair types and textures, and is especially beneficial for blondes, porous hair or anyone wanting stronger, more reliable colour results.
Can I have Metal Detox without a colour service?
While Metal Detox is optimised for use with colour, balayage or lightening services, it can also be used as a standalone detox treatment or add-on during cutting and blow-dry appointments, particularly if you have fragile, breakage-prone hair or live in a hard-water area. Speak to your stylist about the best option for you.
What results can I expect from Metal Detox?
You can expect up to 87% less breakage during and after chemical services, 100% more reliable and even colour results, and hair that feels stronger, smoother and shinier. Results depend on your starting hair condition and home care, but most clients notice improved manageability and colour longevity straight away.
How often should I have Metal Detox treatment?
For best results, have Metal Detox with every colour or lightening service—typically every 8 weeks. Between salon visits, use Metal Detox shampoo and mask at home to maintain protection against metal buildup and keep your colour vibrant.
What happens during a Metal Detox treatment?
Your stylist applies a light pre-treatment spray to dry hair, combs it through and leaves it on while mixing your colour. After your colour is processed and rinsed, a sulfate-free cleansing cream removes neutralised metals, followed by a mask or conditioner chosen for your hair type, left on briefly and rinsed. The entire process happens within your usual colour appointment.
Is Metal Detox suitable for all hair types?
Yes, Metal Detox is suitable for all hair types and textures, including fine, medium and thick hair. Your stylist will choose the right mask or conditioner for you—lighter formulas for fine hair, richer masks for thicker or chemically sensitised hair—to ensure optimal results.
What aftercare is recommended after Metal Detox?
Use Metal Detox shampoo at home to gently remove new metal deposits and maintain colour vibrancy, followed by the Metal Detox mask on towel-dried hair for about one minute. Avoid harsh clarifying shampoos, minimise excessive heat, and protect your hair from hard water where possible. Your stylist will recommend the best routine for your hair.
How is Metal Detox different from a clarifying shampoo?
Unlike clarifying shampoos that only cleanse the surface, Metal Detox uses patented Glicoamine technology to target and neutralise metals inside the hair fibre. This protects the inner structure, reduces breakage and improves oxidative colour and lightening outcomes—it's a professional system rather than a simple surface cleanser.
