TLDR Using chelants in hair dye reduces fiber damage by preventing harmful radicals.

The study demonstrated that the use of permanent hair coloring products could lead to the formation of free radical species, such as hydroxyl radicals, due to the reaction of hydrogen peroxide with redox metals like copper absorbed from tap water. These radicals were shown to cause measurable damage to keratin fibers. The research found that incorporating chelants, specifically N,N′-ethylenediamine disuccinic acid, effectively prevented this metal-induced radical formation, thereby significantly reducing fiber damage. This chelant was particularly effective due to its ability to bind low levels of copper even in the presence of high levels of calcium found in hair.
