You MUST try the Synergy Shaving Soaps from
How To Grow A Moustache - A Guide To Facial Awareness & Lifestyle . After having tried many other soaps, this is among the best I've ever tried!! Best of all, you can get them quickly and easily from Amazon, or order direct from their website. The also sell razor, moustache wax, shaving oil, etc. Everything you need. It is now my one-stop-shop for moustache, beard and shaving needs.
I think Bay Rum synergy soap is the best!
