Review (4/5): What do you know, it works.
I bought this product for my wife, but I got the idea to start putting it on the patchy spots in my beard, and low and behold it has made a difference in two weeks. The hair that has grown in is lighter in color, but I have blonde and black hairs in my beard anyway. The tube is very tiny, but it doesn't take a lot to make a difference. I have been putting this on daily for about two weeks and you can hardly tell that we have used any.
