L'Oréal Professionnel Paris Metal Detox Leave-In Hair Oil — Anti-Frizz Heat Protectant, Color-Protecting Lightweight Oil (for Dry

L'Oréal Professionnel Metal Detox Leave-In Hair Oil is a lightweight, professional leave-in treatment that detoxifies metal build-up, protects color and heat-styled hair, reduces breakage, and leaves strands soft and shiny.

This salon-grade leave-in oil is designed for all hair types, especially dry, damaged, or color-treated hair that needs extra protection from the invisible effects of hard water and styling heat. Formulated with glicoamine, the formula targets metal deposits that can dull color and weaken strands, while delivering anti-frizz benefits, slip for easier styling, and long-lasting shine without a greasy finish. Use after washing or as a finishing step to help maintain color fidelity and reduce hair breakage between salon visits.

How does this oil neutralize hard-water metals and protect hair color?

The product contains glicoamine, a molecule that binds to metal traces left by hard water and environmental sources, preventing them from accelerating color fade and causing hair roughness. Regular use as a leave-in helps preserve tone and reduces the oxidative effects metals can have on dyed hair.

• Binds metal particles to limit color dulling and brassiness.
• Helps maintain true-to-tone color for longer periods.
• Recommended to pair with Metal Detox Shampoo and Mask for deeper metal removal.

Will it protect hair from heat styling and reduce frizz?

Yes — the lightweight oil forms a protective layer that helps defend against thermal stress from blow-dryers and styling tools while smoothing the hair surface to cut frizz. It works as a thermal barrier without weighing hair down or leaving a heavy residue.

• Apply 1–2 pumps to towel-dried hair before blow-drying or styling.
• Provides anti-frizz control and smoother styling playability.
• Can be used post blow-dry to tame flyaways and add shine.

How does the oil improve hair strength and shine?

The formula enhances conditioning, reducing mechanical breakage and improving hair manageability. According to formula testing, it visibly increases surface smoothness and reflective shine while lowering breakage compared to non-conditioning routines.

• Delivers slip for gentler combing and less snapping.
• Boosts shine for a polished, glossy finish.
• Helps decrease breakage through conditioning and smoothing effects.

How do I use it in my routine for best results?

Use 1–2 pumps on towel-dried hair after cleansing and conditioning, distributing evenly from mid-lengths to ends. You can leave it in as a styling base or add a small amount after drying to polish and control frizz.

• Apply after Metal Detox Shampoo and Mask for optimized metal removal and protection.
• Do not rinse out; style as usual or use a small drop for finishing shine.
• Suitable for daily use or whenever extra protection is needed.

Who is this for: L'Oréal Professionnel Metal Detox Leave-In Hair Oil is ideal for people with color-treated, chemically processed, dry, or heat-styled hair who want to protect tone, cut down on frizz and breakage, and add salon-worthy shine. It’s also a smart choice for anyone living in hard-water areas or who regularly uses hot tools and seeks a lightweight protection that won’t weigh hair down.
