Hey! there..I am from India and for the longest time, Indian women have relied on Henna to color their hair. Henna in Indian salons colors hair in shades ranging from brown, red, dark brown, black etc based on a combination of ingredients - like tea, coffee, beets, cinnamon etc.

Although the effects are temporary it is better for the hair (does not penetarte the shaft, henna is a good hair-conditioner) and overall health.

I read somewhere that the natural hair color market is 10% of the annual $1.25B hair dye market..and growing fast.

Many companies like, Avalon Organics, Aubrey Organics, Dessert Essence Organics, Jason Natural Products and Simply Organic make all-natural hair colorings..I have not tried them yet, but I am pretty certain, switching to natural dyes will be compelling to many of us trying to do our bit to reduce the carbon footprint..:)
