I have been using it for two years, I wouldn't call it a wax but more like clay, it is very black and spreads perfectly. I have tried every black product available in gel, clay, and wax form and I have ended up with this one. The only negative thing I would say is that it slightly smudges when you touch your head and rub it on a pillow, but not too much. When you touch it with your hand, it doesn't come off at all, and I forgot to mention that it completely covers gray hair.
