Here's an Earth Day-flavored freebie for your hair: "like" Garnier Fructis on Facebook, and you can get a free sample of their new, greener 'poo and conditioner. How green is it? Well, the shampoo is 94% biodegradeable, and the conditioner is 92%. Neither contain any dye, and the bottle is 50% post-consumer recycled plastic. Not too shabby, huh?
Oh, you might also have to take some sort of hippie vow to do something green, but you're probably doing that already, right?
