Having recently completed treatment for breast cancer, I wanted to find a healthy alternative for coloring my grey. Also, my hair that isn't grey was growing back much darker. At my age (63), I prefer lighter haircolor. I was concerned that I would not be able to lighten it to my former copper, using an herbal product. I read reviews that recommended ordering a color two shades lighter than the color desired. I did this and my hair turned out perfectly. No smell, no trouble. This product is the best. I'm recommending it to all my friends and relatives, and have already passed the word to the nurses in my oncologist's office.
