What It Is

A pre-treatment that neutralizes metals inside the fiber before each color, balayage & lightening service.

What It Does

• Netralizes metal before a color, balayage or lightening service.

• Provides 87% less breakage.

• Delivers 100% reliablle color results.

• Is compatible with all lightener & hair color brands.

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.

Before a color, balayage or lightening service:

• Spray (Mist) on dry hair, focusing on the lengths. Keep the trigger spray 8 in. away from hair.

• Short hair - 8-10 sprays.

• Long hair - 15-20 sprays.

• Let it air dry, while prepping formulas.

• Do not rinse. No added time needed.

• Follow with color, balayage or lightening service.

Powered by glicoamine, the only active agent small enough to trap & neutralize metals inside the hair fiber.

Rated 3 out of 5 by from Not impressed I'm not sure that I would use this product again. I was not impressed. I did not notice a difference with my hair after using.

Rated 4 out of 5 by from great for blondes with well water! I received this product for review purposes and immediately tried it on my clients who have well water. It did a great job of brightening their blonde and making the hair softer and more manageable.

Rated 4 out of 5 by from Good Good pre-treatment to remove metals before coloring service. Nice it’s a spray bottle.

Rated 3 out of 5 by from Just Average.... No noticeable difference even after a couple uses. while the product concept is great for the protection of regularly colored hair, preventing breakage and hair protection, I didn't notice much of a difference. I liked that this was a spray instead of a cream or alternate base form. Although, the end result left the hair soft and manageable in a hard water and cold weather climate, it was overall still average.

Rated 3 out of 5 by from No noticeable difference after one use I like the idea of this product as a pre-treatment for coloring services. The best part is that it’s a spray bottle which makes it easy to use and provides even coverage. I was able to target and spray more on the ends. There was not a noticeable difference after doing a permanent color service but hair was soft and manageable. I think this would be something that needs continued use.

Rated 4 out of 5 by from It was just okay. I didn’t dislike this product but I didn’t love it either. I felt like it didn’t make a huge difference while coloring hair. I didn’t get a chance to use it before lightening. My clients hair felt a little softer.

Rated 5 out of 5 by from Perfect canvas I love how this pre treatment spray creates a perfect canvas. I have used it before both lightening and deposit only color services and it works amazing. I don't go without it anymore because I get great results every time!

Rated 4 out of 5 by from Excited to keep using this! I’ve only used this for permanent color but I’m excited to try it before a global blonding. For permanent color I noticed that I definitely got better gray coverage and it deposited more evenly. I live in a city with pretty hard water so this is a game changer! I received this product free as part of a sampling program.

Rated 5 out of 5 by from Great way to reduce breakage I noticed hair was softer, shiner, and helped to keep color vibrant. I also noticed a visible reduction in breakage when used before lighting services.

Rated 4 out of 5 by from Will use with lightener but not color Used before a color and it definitely helped with porous ends however I feel it weekend the color and made it somewhat translucent

Rated 4 out of 5 by from Would probably buy again Overall, I think this does a great job. All of my clients seemed to like how their hair felt. It didn’t seem to impact lift for my blondes either!
Date published: 2025-01-06
Rated 4 out of 5 by from Nice, but works cumulatively I like the way this product worked. smells nice, leaves hair feeling smooth. But I think it would take several uses to really see a huge difference in aiding in the metal buildup removal & removing any/all brassiness.

Rated 5 out of 5 by from So good I love this so much. It protects my clients hair really well
Date published: 2025-01-06
Rated 4 out of 5 by from Worth trying if you have hard water clients Overall I didn't mind using this. It's easy to use and seems to make the hair porosity a little more even. I definitely would have to use it for longer on regulars to see what the real effects are.

Rated 3 out of 5 by from Made hair sticky, unoticeable results. It smells good, its hard to tell how effective it really is. I sprayed it all over before a highlight service. It made the hair feel sticky (like a sea salt spray), making it difficult to foil. My client liked how it smelled. It did seem like her raw lift was a tad brighter than normal. I personally probably wouldn't purchase this product again.

Rated 3 out of 5 by from Works Didn’t love the way it made my hair feel. But seemed to have better application of color after
Date published: 2025-01-06
Rated 5 out of 5 by from Highly recommend! I used this product before a lightning service. I have hard water in my area so a lot of times blonde doesn’t come out as bright as it should. I used this product on a blonding service for new growth. I am pleased to say the blonde came out beautifully! The hair was also nice and strong.
Date published: 2025-01-06
Rated 5 out of 5 by from Buy it. Love this product! It truly helps remove buildup from the hair. I had a client whose blonde locks turned a bit orange from her well water and this took it out while her highlights were processing. Time saver and hair helper.

Rated 3 out of 5 by from Not my favorite Didn't see a big difference. I think I used too much and made the hair somewhat sticky
Date published: 2025-01-06
Rated 5 out of 5 by from Great stuff! This really helps prepare the hair for a nice even foiling. I could see the buildup coming off when I rinsed. It also leaves the hair feeling very soft & manageable

Rated 5 out of 5 by from Like k18 Very much like k18, spray. Do the color and shampoo/condition.

Rated 4 out of 5 by from Great aid in highlighting I enjoyed this product when using it for highlighting. I noticed it help lift with an effortless ability in a short amount of time.
Date published: 2025-01-04
Rated 4 out of 5 by from Worth it! This does help with pulling any metal build up off of the hair to make the hair lift not only better but more even, it help to pull through the brass.
Date published: 2025-01-04
Rated 4 out of 5 by from Left the hair smoother and feeling softer I did not notice an effect on the color but I did consistently notice the hair feeling softer, looking shinier, and blow drying was much easier after using this product. I like the smell and it was easy to use. It did not effect the processing time.

Rated 5 out of 5 by from Great for areas with hard water Thank you L’Oréal for letting me try the Metal Detox Professional Pretreatment spray in exchange for my review. I applied the spray to prepare hair before my client’s coloring service because we have older plumbing and hard water in our area. Depending on the amount of metal in hair, it can cause breakage, dull or uneven color, and less predictable results when lightning the hair. The leave-in spray quickly absorbs into the hair to neutralize and removes metal deposits. I used in conjunction with the Metal Detox Shampoo and Mask to help protect the hair against receiving new metal particles. The spray does not have a smell or heavy feeling to it. This service only took an additional 5 minutes. My client’s color took beautifully, very even and shiny.

Rated 5 out of 5 by from Metal Detox Pretreatment - Amazing! This product really works well to avoid brassy hair and seems to help keep color longer.Amazing!
Date published: 2025-01-03
Rated 5 out of 5 by from Use it everytime Great product! I noticed it does wonders with more even colors and nicer lifts. I like the way the hair feels after services as well.
Date published: 2025-01-03
Rated 5 out of 5 by from Great The smell of the product was nice, I noticed it had more of a smoothing effect after use. It didn’t weigh the hair down or leave any residue.
Date published: 2025-01-03
Rated 5 out of 5 by from Hard Water Hates to See Metal Detox Coming I live in an area with extremely hard water and this product has been very helpful. Chemical services have a more favorable outcome when I use this product. Color processes more evenly, and the hair has life instead of just laying flat.
Date published: 2025-01-03
Rated 3 out of 5 by from I don’t really get it I think over time I would be able to see the benefits of this product. But only using it for a short time with the sample given, I just don’t get it.
