Honey, it comes from a plant, FFS. Not only is it Green, it's green! No chemicals, no horrid chemical stink, no BS, no PITA, no big expense. Your hair feels and looks and acts much happier and healthier than after an at-home or expensive salon dye job, too. It's easy to do yourself, but it's more fun if you get a goodly amount, grab a friend and some gloves, and help each other glop it on and wrap it up.

If it was good enough for Lucy, and if it's good enough for a zillion women worldwide (inc their palms and soles), it's good enough for you, too.
My pal Mark loved it - I'd help him and give myself a Red Stripe in the process - so it's good enough for you men, too, also.
