My mom has been using this product for years to cover her roots and I've used it in high school to color my hair. After years of use, it has made my mother's scape super dry. I've stopped using a few years back and haven't gone back. It's good for those every once in a while looks. But don't depend on it for year after year.
LOVE LOVE LOVE. Super gentle for my sensitive skin and takes off make-up! It's kind of pricey for even the smaller size bottle so I would try to get a sample at sephora to test try. If you are willing to spend the money, it's totally worth it. Just don't get addicted.
