What Else You Need to Know

Everyone has metals in their hair.

• The cause: Metals erode in our pipes, mixing with our water and ultimately accumulating inside the hair fiber.

• The consequences: When metal particles mix with hair color and lightener oxidants, they can lead to unreliable color results and breakage.

• The solution: Metal Detox.

After cleansing with Metal Detox Shampoo:

1. Apply evenly on towel-dried hair and leave on for 1 minute, or 2-5 minutes for high formation hair.

2. Rinse thoroughly.

Rated 5 out of 5 by from Best hair mask Best mask I’ve ever used. It’s so powerful even the most dull hair it will bring back to life. My hair has never looked better after using this.

Rated 5 out of 5 by from A fantastic mask I really like this mask. It’s thick and creamy but it doesn’t weight my fine hair down at all. I use the entire system, pretreatment and shampoo and I definitely noticed a difference in both the feeling and the tone of my hair. I highly recommend this to anyone but especially to anyone living somewhere with hard water.

I started using it once a week with the whole system. My hair looks and feels so much healthier. I have noticed less breakage and my hair doesn't feel like it has a ton of buildup on it. This is a must have!!

Rated 5 out of 5 by from Great product line I received this product for free and exchange for a review. I have been using this product line for years. I especially love the metal detox shampoo and the mask is great as well. I leaves the hair feeling soft and shiny. It can be a bit heavy on finer hair so I just use a little bit less, but it makes dry ends feel smooth and healthy again.

Rated 5 out of 5 by from Great all around mask This product works really well with the other products in the system. As a stand alone mask it’s definitely nice and moisturizing but works best with the treatment and shampoo. Smells amazing and leaves the hair feeling soft and bright.

Rated 4 out of 5 by from Great This metal detox mask made such a noticeable difference in my hair. It left my strands feeling lighter, softer, and noticeably shinier without stripping or drying them out. My color looks brighter and more even, and my hair feels healthier overall. I love that it helps remove buildup from hard water and environmental metals—especially important before or after color services. Definitely a staple in my routine now.

Rated 5 out of 5 by from Great I have been very impressed with the L’Oréal Metal Detox Mask. It feels like the perfect finishing step in the Metal Detox routine, restoring moisture and softness without weighing the hair down. After using the mask, my hair feels deeply nourished, smoother, and noticeably healthier, especially after a detox-focused shampoo. What I appreciate most is how well it balances hydration with lightweight conditioning. My hair feels softer and more manageable immediately after rinsing, and the brightness and clarity of my color remain intact rather than muted. The mask helps seal in the benefits of the detox process, leaving my hair feeling polished, silky, and easier to style. I received this product for free in exchange for an honest review, and all opinions shared are my own. This mask has become a staple in my routine and pairs beautifully with the Metal Detox pre-treatment spray and shampoo. I would confidently recommend it to anyone looking for a deeply conditioning treatment that supports hair clarity, shine, and overall hair health.

Rated 4 out of 5 by from Wonderful mask! I love the smell of this product! The shine is wonderful without feeling heavy or greasy. My only complaint it the label is too thin, making it nearly impossiblew to read without putting something behind it.

Rated 5 out of 5 by from Instant softness without weighing your hair down [Employee of saloncentric] This mask is a game changer. It makes my hair incredibly soft, shiny, and manageable without feeling heavy or greasy. After using it, my hair looks healthier and feels stronger, especially on the ends. A little goes a long way, and it works fast. Perfect for restoring hair that’s been colored, heat-styled, or exposed to hard water.

Rated 5 out of 5 by from Game changer for color and hilights This metal detox is a game changer. The shampoo pulls out the mineral buildup from the hair. And the mask fills in the so to speak holes that are left in the hair to keep the minerals from building back up temporarily. The hair immediately feel soft.

Rated 1 out of 5 by from Terrible scent I noticed some difference, my hair was softer after using but the smell is unbearable. The Malibu c hard water packets work way better and don’t smell. Even after blow drying with products you can still smell this mask. It is over powering and smells like cheap men’s cologne. Almost want to throw this product away.

Rated 5 out of 5 by from Game-Changer for Healthy, Silky Hair! I am absolutely obsessed with this product! After just one use, I noticed a huge difference in the way my hair felt and looked. My strands instantly felt softer, smoother, and more manageable, like I just left the salon. The texture is rich but not heavy, and it melts beautifully into the hair, coating every strand without weighing it down. What really impressed me is how healthy and revived my hair feels. This mask deeply nourishes and protects against the build-up of metals and impurities that can come from water or coloring, which is something I never realized was dulling my hair before. After rinsing, my hair looks shinier, feels stronger, and is noticeably less frizzy. Even better, it doesn’t just give temporary results—it feels like it’s actually improving the health of my hair with every use. The scent is also absolutely luxurious—fresh, clean, and salon-quality. It lingers lightly in my hair, making it feel refreshed and pampered throughout the day. I’ve gotten compliments not only on how soft and glossy my hair looks, but even on how amazing it smells.
