Query: OhYes!

I first observed this product on a friend's hair, who, like me, leans towards natural products. It looked great! I never even thought I'd color my grey...I was going to be one of those aware, "sage women." But when I saw the difference it made, I tried this product. It was easy, gave me great color, and did not smell nearly as strongly as what I've been exposed to on others. The irritation factor is also low to non-existent (changes from time to time).I've been using it for about eight years now.
