For a few years now and getting older I have gotten uneven streaks of gray in my moustache. Which I hate because it interrupts the shape line. So I have gone to Sally Beauty Supply to get dye to cover or fill in. I have no idea if the females working here have an knowledge or not, but I do know they are always very nice. The store it self as are all of them a pain in the ass. The isles are narrow and I mean narrow, get to big butted folks from apposing ends and one will have to turn around and come in for the other side. Or if as most often is a person leaning down to read a produce, forget moving for a few minutes. But other than that it is a fine supply joint.
