Query: Most safe and gentle hair coloring

I love this product and am very sorry that Clairol has chosen to discontinue it. No pyroxide and no ammonia...just easy to apply and goes on evenly; washes out so that the "root" thing doesn't happen. My hair always shines and glistens after using this hair color.Seller was excellent, rapid delivery and product just as described!
