Growing

The average human male grows 25,000 hairs on his face in the space of 24 hours. They will grow about half a millimetre in a day and 13mm in a month.

Genetic

Genetic factors determine the length, texture, colour and growth patterns of facial hair. Another factor that plays a part in hair growth is hormones.

Tug of war

Legendary King Alexander the Great ordered his soldiers to shave, as he feared that in battle the enemy could easily grab their bears and kill thim.

Plucking

The great Roman ruler Julius Caesar had his facial hairs pulled out one by one by tweezers, rather than trust anyone to use a razor on his throat.

Wet and dry

When put under a microscope and examined, a wet razor shave looks much smoother than a dry shave carried out by an electric shaver.
