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 I have several clients that have well water and I’ve been preparing their hair with Metal Detox line for about 6 weeks now. I am in love with the results. I start my chemical services with clean hair now. Specially for my blondes. You can feel a difference on the hair after the first use. The lift on the hair has been less orange since I started using this products. I use the mask after I tone my chemical process. To seal in the color and help longevity of the service. My clients have been in very happy with their new results.

Rated 5 out of 5 by from Impressed I used this product with the recommended system at home before deciding to bring it into the salon, and I can say I actually noticed a difference in my hair after one wash. My natural waves were more defined. My hair felt cleaner, lighter, soft, and hydrated. I was impressed and I look forward to continuing use of this system and implementing it in salon services.

Rated 5 out of 5 by from Love this! The L’Oréal Professionnel Metal Detox pre-shampoo, shampoo, and mask has been a total game-changer—especially for anyone dealing with hard water or mineral buildup. From the very first use, I noticed a dramatic difference in how my hair looked and felt. The pre-shampoo does an incredible job of gently removing metal and mineral residue without stripping the hair, which sets the stage for the shampoo and mask to actually work at their full potential. After the full treatment, my hair felt noticeably softer, lighter, and healthier. My color looked brighter and more even, and my highlights had new life again—less dullness, more shine. One of my favorite things is how quick and efficient this system is. It delivers professional-level results without long processing times, making it perfect for both in-salon treatments and busy clients. I also noticed improved curl hold and overall manageability, which is a huge win for color-treated and extension clients alike. This is an absolute must for anyone with hard water, frequent color services, or hair that just isn’t behaving the way it should. I confidently recommend Metal Detox to my clients and will continue offering it as a professional treatment in the salon.

Rated 5 out of 5 by from I recently had the opportunity to try L’Oreal's Metal Detox Mask. It made my hair feel softer, brighter, and shinier. I would definitely recommend using this product especially with the full Metal Detox line.

Rated 5 out of 5 by from Best mask ever! Hands down best mask. They hit the mark with this one. The smell is nice, but the ease in using it and the results speak for themselves. Hydration and protection for your hair like no other!

Rated 5 out of 5 by from Great for hydration after shampoo! Loved this mask for hydration after using the detox! It helped add back in moisture while not weighing down my hair at all. I really loved using all three treatments together and will def be adding this to my back bar!

Rated 5 out of 5 by from Standout mask The L'Oréal Metal Detox Mask is more than just a deep conditioner; it’s a protective shield. If you find that your hair color turns "muddy" quickly or your hair feels brittle after your salon appointments, this is worth the investment. It bridges the gap between a standard moisturizing mask and a technical repair treatment.

Rated 4 out of 5 by from Decent if needed Got this free to try. The system as a whole works well and this is a great add on. However, there isnt a lot of people in my clientele that need the metal detox. Also, this system seems to have an issue with scent. Its so strong!

Rated 5 out of 5 by from shes a keeper Adds great slip, easy to use smells great. Have been using since the line was introduced and have been happy with results everytime. (I use the entire regimen)

Rated 4 out of 5 by from It’s ok but I’m not ecstatic about it! This product I think would work well I areas where large amounts of metal are present in the local water. This did make my hair a bit softer but I didn’t see a big change in myself or others I used it on. I gave it 4 stars because I typically like this brand.

Rated 5 out of 5 by from beautiful hair I received this as a sample in exchange for a honest review . I loved this mask!the hair was soft and very manageable . It is part of a 3 step process . I would highly recommend the system to anyone with well water or metal buildup

Rated 5 out of 5 by from Love it! Great mask. Hair was so soft after use. Fingers ran right through it when it was still wet. Perfect ending! The smell reminded me of a chemical Christmas tree, wasn’t sure what to make of it. I kind of liked it, but the chemical smell threw it off for me. Overall, I enjoyed this product and will get past the scent, because if a product can make my hair soft and untangled, it’s a win for me!

Rated 5 out of 5 by from Great mask I really loved this mask. It leaves the hair feeling so soft and makes it so much easier to detangle and blow dry. A little but goes a long way and it’s moisturizing enough for coarser hair while still being light enough for finer hair. It has a citrus and musk scent that I really liked. It’s a piece of a multi-part system and works better with the pretreatment and shampoo, but I found it still works well on its own.
Date published: 2026-01-08
Rated 5 out of 5 by from Amazing Most hydrating mask I’ve ever used. Completely revives the hair. Use in the system for best results.
Date published: 2026-01-08
Rated 5 out of 5 by from Perfect I love this mask in conjunction with the pretreatment shampoo and shampoo. This is great for after a scalp treatment, buildup removal or application of a toner. Ideally you can use this whenever I just prefer it for these specific services. Price point is perfect. A little goes a long way so it’s a great bang for your buck! It’s lightly scented but still leave a gorgeous hint of fragrance on the hair.

Rated 5 out of 5 by from Best mask! Great mask that is so moisturizing and luxurious! Great for all hair types and works the best with the whole 3 step metal detox process— with the pre-treatment and shampoo. But does perform well on its own! So much shine and manageability after use.

Rated 5 out of 5 by from Detox, then Induldge This mask isn’t here to just feel good — it delivers real reinforcement where hair needs it most. After shampooing, it dives in to trap and neutralize metal particles inside the fiber while giving hair a surge of moisture and slip. The result? Smoother, silkier, more resilient strands that handle styling with less breakage and show richer, more vibrant color. Whether you’re maintaining processed hair or prepping for your next service, this mask makes hair look and feel healthier without weight or residue.

Rated 5 out of 5 by from Good product I received the 3 step system in return for an honest review. Overall, this is a great product. I have used it two times so far and my hair feels clean and the mask does It’s job. My hair is left feeling soft and manageable. Definitely recommend this product.
