Herb For Men Mustache & Beard Dye (Deep Brown, 3 Pack), PPD-Free Ammonia-Free, Vegan with Natural Ingredients, Odorless, Gentle for Sensitive Skin, No Skin Irritation

Excellent product. After having developed an allergy to another product that contains PPD, I decided to try Herb for Men (deep brown). The application method is a little different (and about 10 minutes longer) than the other product, but certainly not more complicated. My experience has so far been great. I haven't experienced any itching, swelling or oozing of my skin under the beard as I did with the other (unnamed) product. It's important to make sure that your beard is washed, clean (oil free), and dry before the application. I was somewhat concerned that the color would be too dark, but the resulting brown appears to be a medium brown that matches well with my natural hair color. I was able to slightly adjust the shade of color by adjusting the application time for both creams. The color seems to last well and gradually disappears after about two weeks once the old gray grows back. When showering, I use a sulfate-free, gentle shampoo without lathering too much on the beard.

Well finally a mustache coloring product that didn't cause an allergic skin reaction. It requires a long process, ie. 20 minutes of long to color the whiskers, but that's a lot better than a burning skin reaction.
