After reading this post, I can say this....and again YMMV but this is what works for me.....

I have bled like a stuck pig every single time I've tried a cold water shave. My hair and skin do not like cold water. I'm softening in the shower, rubbing my face with later, and keeping my skin soft post shower until I start shaving.

I don't even experiment with it anymore. I just do hot water shaves.

Hope this helps a bit???
