Hairstylist Kathy Nunez Answers 9 Questions about L’Oreal’s Metal Detox



We all love surprises, except when it comes to our hair coloring services. There’s nothing worse than trying to carry out a successful color application for your client only to be left with unexpected results, like say a patchy all-over color or worse—orange-tinted strands. 

Unfortunately, surprises like these are pretty much inevitable thanks to the appearance of heavy metals, like copper, in our water, aka “hard water”. You see, with every wash or shower, these metals in our water start to build up and accumulate inside the hair fiber. For colorists, this accumulation of metals is pretty much their worst nightmare, because when metals in the hair come in contact with oxidants during color, balayage or lightening services, it can lead to  breakage and negatively impact color results for their clients.

Thankfully, L’Oreal Professionnel Paris has the perfect solution to combat these issues: Metal Detox. This breakthrough professional protocol is capable of neutralizing metals and detoxifying hair, thanks to its key ingredient glicoamine—the only molecule small enough to penetrate and target metals inside the hair fiber. Not to mention, the three-step system is compatible with all hair color and lightener brands and includes a pre-treatment to neutralize metals before color services, a cleansing shampoo to detoxify hair after the service, and a conditioner/mask option to prevent new particles from combing back. Most importantly, the results are incredible: 87 percent less breakage and 100 percent reliable color results.

Given the innovative nature of Metal Detox, it’s only expected that stylists will have a lot of questions about how best to utilize this treatment system in their salon and with their clients. That’s why we reached out to hairstylist and blond specialist Kathy Nunez, who’s quite the expert on all things Metal Detox. From how to price the treatment in your salon to when to use certain products in the system, she’s here to answer all of your burning questions.
