Hi Jenn,
Avoiding putting more 'stuff' into me is a big reason as to why I have never colored my hair. Although I do have to admit that as a redhead, I'm not going gray, but white. So I now look more like a platinum blonde more than a redhead!!
Also - I'm too lazy to keep up with coloring my hair!!!!
I do believe your thinking is correct though - we spend a lot of time & effort in detoxing - we
do need to be very choosy about
what we voluntarily put into & onto our bodies!!!
