The appearance of one's hair is an important signal to others. Coco Chanel observed that
“A woman who cuts her hair is about to change her life.”
Sometimes the matter of hairstyle is not a question of personal choice. In North Korea 2014 hairstyles of students are dictated by the government. Only 18 styles for women after marriage ( less before marriage) are allowed.
For North Korean men 10 styles for are currently stipulated .
Older men, whose brains are presumably already rotting away anyway, are allowed hair as long as 7 cm.The programme allows men aged over 50 seven centimetres of upper hair to cover balding. ( a redundant concession in my case !)
The edict stresses the "negative effects" of long hair on "human intelligence development", noting that long hair "consumes a great deal of nutrition" and could thus rob the brain of energy.
It got me wondering
"What might be a Selling lifestyle hairstyle ?".
