Today was my third shave with the Jack Black Supreme shave cream and, I must admit, I like it more and more each time I use it.
I did discover that it works best if you don’t add any additional water (other than what’s on your wet face between rinses). I had been treating it like other traditional shave creams, adding little dribbles of water to make a deeper lather. This doesn’t work with Jack Black, it just dilutes and thins it out. But even with the Simpson Wee Scot (the world’s smallest fully functional shave brush), it creates a plentiful lather for three full passes, and provides a very slippery and well cushioned substrate for the DE blade.
