The truth about cosmetic science is that there is not much basic research going on. In fact, there are a number of questions that remain unknown primarily because no one has taken the time or spent the money to investigate them. However, that doesn’t mean there is no basic research happening, for example there is this story about research conducted on hair by P&G scientists.
Copper is bad for hair
In their studies, researchers determined that one cause of damaged hair is a build-up of copper in the fibers. This copper comes from tap water and is soaked up by the hair. Once in there, it catalyzes all kinds of chemical reactions that break down hair from the inside and cause damage. And damaged hair is unruly hair.
Formulating for damage
While conditioners are proven to make hair better, this research suggests you could improve your hair formulations by adding chelating agents like Disodium EDTA. I’m not sure if you will see a measureable effect but this is a great area for further experiment. So, the next time you’re creating a hair formulation, crank up the level of EDTA and see if you notice any difference. You might just reduce hair damage.
