I just read this interesting article on wet shaving.
I have used a shaving brush for some time and I do think it helps.
I also use the following shaving cream:
This cream is glycerine-based (like the article recommends), lathers very well (a little bit goes a long way), and my wife digs the lavender smell.
I’ve never used the Trumper’s stuff (although I am curious about it because I’ve seen good things about it on the Web) so I can’t compare The Art of Shaving to Trumper’s.
