Hair dye is better living thru chemistry :)
LOL!
Why?
I come from a family of pre-mature grays. One or two Aunties were au naturale (no coloring for them). For the rest of us...well, we keep the chemical manufacturers in business. Seriously, I started going gray in middle school (just a strand or two). By HS my cool Aunt Cel got me 'started' and I have never finished coloring (and don't plan too). Just a choice :)
