no die in dye

so, i don't know if it's the end of winter or this weird haircut I gave myself, but i'm thinking about hitting the (dye) bottle again.
However, I don't want to hurt myself or anyone else in the process: which is why i'm checking out eco colors
and looking into other options from this great article on treehugger.
in general, beauty products are bad news for the environment, animal testing or extra packaging: does anyone have any good resources/companies/etc to share?
