The biggest disappointment for those who love red hair is that the color's longevity is much lower compared to other shades. No matter how high-quality the dye, reds fade faster. This isn't due to the quality of the dye itself, but rather the molecular structure of the pigments.


The vibrant, bright pigments that create red hair are classified as "Block" secondary dyes in chemical terms. The most defining characteristic of these pigments is that they don't react after penetrating the hair and therefore don't swell. "Unblock" dyes, which create permanent shades like brown or black, swell and become trapped within the hair through a chemical reaction. Because red pigments don't swell, their molecular size remains small, and they wash out of the hair much more easily with each wash.


Practical Implication: This means the fate of your red hair isn't solely dependent on the dye brand. To increase color longevity, using sulfate-free and color-protecting shampoos and conditioners that slow down the removal of molecules from the hair and seal the cuticle is a chemical necessity.
