Hmmm not quite what we were expecting [SEP] My husband has been complaining of the grey in his beard, and I had read so many bad/scary reviews on the chemical dyes that I wanted him to use something "natural." This popped up and I read the info on the website and the reviews on Amazon and decided to purchase it for him. We purchased the base and the dye, and like what happened with many other reviewers, it gave his beard a slight green tinge even after following the directions perfectly. Yes the dye darkened over the next 24-48 hrs, but it didn't quite reach the level of darkness that we were hoping for, and there was always that slight tinge of green. It wasn't enough to bother my husband, thankfully, so he'll definitely keep using it until it's gone.
