My husband had been complaining about the gray hairs in his mustache.  So I bought him a bottle of Just for men touch of gray.  He likes this product very much because it looks natural and it blends well with the rest of his mustache. I bought the Dark Brown shade and I was afraid it was going to look fake looking, but it is actually very natural looking. Also, you can apply it very sparingly (so you can keep most of the gray), a little more, or use a lot so you will just have a small amount of gray.  As he only uses it on his mustache, he only uses a little bit of the bottle.  The information packet states that you must discard after one use - but  he has used the same bottle three times now and it works just fine.   It will keep just fine as long as you do not expose it to the air. This is a no-mix product.  You simply open the bottle and start combing it into your hair.  As far as applying, if using just on your mustache, use an old toothbrush (just make sure there is no left-over toothpaste on it.)  This will work perfectly.
