Hair cutting can be a sign of a psychopath with a fetish as well as of a bully....
In the late 90s there were a few episodes of women having hair cut off on buses locally to my home by a strange man.
Then there was a very gruesome murder of a local woman.... and police found some of the cut off hair from the women on the buses placed on or near her body.
Luckily the total psychopath was caught before he murdered again - it turned out he'd murdered a schoolgirl plus cut the hair of strangers in his home country, but not been caught there!!
Also hair is of historic importance to women as a sign of femininity.
The Nazis shaved the heads of female death camp victims to degrade them & make them feel less human. (As well as to use the hair to make cloth).
The French Resistance shaved the heads of female Nazi collaborators again to insult their femininity & make them stand out amongst other women.
Many women (myself included) who have lost hair to medication, chemo or alopecia will know how hurtful & upsetting it is to your sense of self.
So for a man or boy to attack a young woman's hair is to attack her in more than just a physical way.
To those who just don't get it, try having empathy.
