This tip comes in from a friend who works in a day spa. They have a "master barber." When they hook you up with their $55 dollar shave service, this is pretty much what they do.
Get your bowl, your brush, your cream and your favorite exfoliate.
Go ahead and put equal amounts in a hot bowl.
Take your wet brush and start mixing it up.
Add water accordingly. You might find it's a little bit too thick at times. You've got a great lather now.
As you typically would, massage and spread the lather all over the parts of your face you intend to shave. It really is that simple.
