Review (5/5): A world of difference.
This works exactly as advertised. I'd started with the [[ASIN:B00T0HZDF6 Organic & Natural Dark Brown Beard Dye]], but noticed that I'd started to turn a little pinkish-purple around the edges of my beard after a week or two (note: most hand cleaners and lotions contain alcohol, so they'll start to tinge your coloring). I had to double the portions to really coat my beard, but the end result was just what I wanted. The purple tinge was replaced by a much more natural looking dark brown.
