I'm glad you started this thread, maverick. It has been fun to hear everyone's thoughts on this topic. One thing that I have discussed a little with Tom is that perhaps with length comes a little easier manageability? Neither one of us uses much product anymore and we were both previously fairly heavy users (of product, ).
I agree with Triibeard, that a pleasing scent is a good reason to use beard oil. I have a few scented oils that I still use when I go out because both my wife and I like the scent. Its no different really than wearing an all natural cologne.
