I must be doing something wrong. I have been a regular user of Wool Fat shaving soap for a couple of years now and have been very happy with it, no matter what razor/blade combination I am using it gives me a clean, close and well cushioned shave. After reading several rave reviews of Tabac Shaving Soap here and elsewhere I purchased a puck a couple of weeks ago and began using it. It lathers well (though not any better than my Wool Fat) but shaving with it has been a disaster. It is as reliably awful as my Wool Fat is reliably good. Again, no matter what the razor/blade combination, if feels as if my blade is grabbing each whisker and pulling it out of my face by its root. It turns even my normally efficient ATT Aluminum SE1 into an unimaginably inefficient shaver requiring multiple passes in all directions. Has anyone else experienced this with Tabac and if so were you able to fix it and how? Clearly a YMMV experience.
Do you bowl lather or face lather? I only ask because when I used to bowl lather, there were plenty of times where I experienced what you did, with various soaps. I learned, after switching to face lathering, that I was under-hydrating my lather on a consistent basis. Face lathering helped, because rather than making a lather that *looked* right, I aimed for a lather that *felt* right. My shaves improved dramatically after that.
All this to say, if your lather looks great, but you feel like it’s not slick enough, try adding more water. Tabac gets very dense and pillow looking with minimal effort, but it takes a little more water to get really slick. Good luck!
