Book excerpt: Nobody will take you by hand on how to grow a beard.It just grows naturally.However,it's genetically designed to grow and for many of us,nobody jumps in to give a beard grooming tutorial.Surely,dad is there to teach you how to shave but you're likely out of the house and on your own by the time you need some beard trimming idea.In addition,since beards are generally a fixture of the past 10-20 years,dad might have never grown a beard for himself.So you're on your own.But,dont be afraid this book is written for you.
