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 hrs but it did not quite reach the level of darkness that we were hoping for and there was always that slight tinge of green it was not enough to bother my husband thankfully so he will definitely keep using it until it is gone
