With reviews, I consider myself really back, but this product really deserves a review: At first I was still quite skeptical. Had several other options and products tested: either the product too expensive or the result was handling too complicated, not optimal. But for this price it was worth trying to make the gray hair in mustache and sideburns finished off. Included in the package are two small tubes whose contents must be mixed together. The handling is really easy. Mix two strands of the same length in the enclosed container with a spatula and briefly with the small brush that is on the other side of the blade, brushing. Two small strands from the tube of about 6 cm in length, however, only go for the mustache. But as time has out you how much mixture has to be prepared if more gray hair to disappear. After brushing his hair or his beard still provide a countdown timer, the best four minutes because the result is otherwise very dark. Then rinse immediately wash out with shampoo. The result is unbelievable: everything Gray was blown away and the hair color including beard seemed very natural. The same is true for graying hair sideburns that now belong to the past. I am thrilled with the ease of use and great results. Faster and easier it gets. Five Stars !!!
