I have been using this product for a long time. I love the new formulation which allows you to mix as you go instead of the one use like the other formulation. The application is better too, they give you a small cup to put the mixture in and a brush applicator to apply the dye. The old applicator was a sponge tip at the end of the bottle which often wore out before you were through your touch up process, This product is easy to use and much better over all than the original Revlon Root touch up, I HIGHLY recommended!!!
