Check out this site for a tea to get healthy color. I have been using the rosemary/sage tea for a number of years. My hair was white and made me look like a ghost but the tea makes my hair a champagne blonde. I was very light blonde as a child and even at the hair salon have gotten comments on the beautiful color of my hair. I do the tea every month after a hair cut and will never use chemicals again. If I can eat the herbs--my hair can have a bath in it, I leave it on about 8 hours, then wash out. Am thinking if it is on longer it will take better but who knows.
