pogonotrophy 

The act of cultivating, or growing and grooming, a mustache, beard, sideburns or other facial hair.

Sam Brinkley was perhaps the world’s greatest authority on pogonotrophy. That’s right, pogonotrophy, the science of beard growing. Sam didn't start out to be an authority. As a young man he simply became disgusted with the speed with which his beard grew. Twice a day he had to shave the stubble from his face. So, in his early twenties he got mad and quit shaving, his wife’s protests to the contrary. His beard grew and grew — down to his chest, down to his navel and down to his waist.
