Shaving

Shaving was practised by multiple people, including the Tenth (TV: Time Crash) and Eleventh Doctors (COMIC: The Lost Dimension) as well as John Who. (PROSE: Nostalgia Corner)

The TARDIS was equipped with several shaving machines. (PROSE: Mire and Clay)

Upon arriving in a street in what he called "Kingdom United", Lucifer got distracted from mimicking a guy who told him to find Lilith by the matter of his inability to shave; as he spoke, he stroked his wirey beard. (WC: )
