You have your hair colored regularly, but unfortunately, you are not always satisfied with the result. Often there are color deviations or even hair breakage. Then change the hairdresser? Does not have to be. Because these problems do not have to have anything to do with his / her expertise. This has now been shown by a new study.
After seven years of research in collaboration with Ioannina University, L’Oréal Professionnel Paris discovered that metal - more precisely copper - in hair can be the cause of color deviations and hair that becomes brittle quickly.
However, they are talking about too much copper here. After all, the element plays an important role in all metabolic processes in our body. Among other things, the pigment melanin, which is responsible for the natural coloration of hair and skin, is first formed with the help of copper.
For the hair coloring process (bleaching, coloration, balayage), high copper content in the hair (from 30 ppm) is not the best prerequisite, as the metal reacts on contact with the oxidant and this can lead to hair breakage and unreliable color results.
The level of metal concentration in the hair varies depending on the condition of the hair, but also on the water quality in the place where you live. Even the cleanest water used for showering contains metal particles. Because the water carries away copper from the water pipes. With each hair wash, more and more of these copper particles accumulate in the hair fiber.
L’Oréal Professionnel Paris has worked with Ioannina University to develop a solution to neutralize those copper particles in the hair during dyeing processes. Glicoamin is the name of the molecule that will be used in future colorations in the new professional service from L’Oréal Professionnel Paris with the name "Metal DX", and which cancels that copper effect - and thus promises reliable colors and less hair breakage.
The results were verified in 102 instrumental tests and more than 1,000 live tests by scientists and three international hairdressers.
