I have been told endlessly by purists that canned foam is fit only for animals. I finally tried it for myself and was very pleasantly suprised. Works just as well as the soaps and creams, but with a fraction of the time and effort.
I was using the Poraso green shaving cream for some time, but thought I'd give the foam a go. It performs just as well as the cream, but spares the time and effort of whipping up the cream into a foam with a brush and bowl.
