Have been using Proraso Green every day for the past few weeks now. Usually a user of Williams Mug Soap. I only own one brush atm, a Simpsons Commodore X2 that I've had for about 3 years. This brush has rarely shed hair, maybe one or two when I bought it but none since, but now I have switched to Proraso I am shedding about two hairs every shave. Surprising since I am now using the brush more gently being as though the Proraso is so soft and loads very easily compared to a hard puck. Was wondering if there is something in the Proraso that is harming the brush? Thinking about picking up a synth if this continues.
