Wally World used to carry a thing called "Shave Secret". It was a small bottle of oil and after showering I would apply it to my head while the skin was still wet. After that I put on whatever shave cream I was using but a really nice one was Cremo which was really slick. The oil in Shave Secret softens the hair a little bit, I guess, but the main advantage I noted was that it seemed to make my skin a little slicker. Head Blade used to have a shave cream also, I don't recall the name but I can't imagine them having given up on it.
I'm not familiar with Bald Bros so I can't give any kind of report on that.
