Hey everybody. I've been using a Merkur long-handle DE razor since 2015. A few years ago (maybe 3?) I stopped using a brush and soap and switched to just using canned shaving cream. In the last month, though, my razor has stopped shaving effectively. I've tried swapping out blades (Shark, 7AM, Treet), but that didn't solve the problem. I also thought maybe the switch from Barbasol to Gillette cream might have been at play, so I swapped to the old puck of Proraso soap I had in the bathroom for my last shave. That didn't fix the problem, either. The razor will slide across my skin not cutting any hair but just removing the cream that's on my face. I haven't changed my technique, at least that I'm aware of. Any idea what might be going on? Thanks for the tips!
