Chemistry / Why are some dyes so long-lasting?

It works by staining the upper layers of the epidermis. The pigments of the dyes/henna seep through to the first layer of the skin. Dyes/henna are recommended to be taken off only after at least 2 hours, the longer it is left it, the longer the dye/henna will last.
Don't get me wrong, but if you wash your hair every day , you are more likely to make the henna/hair dye fade faster, compared to another person who washes their hair once a week. (as an example)
