I am not sure about this.
I have a lot of baggage, yet have medium length hair.
I can tell you that when a member of my family committed suicide, I had my hair cut 3 times in under a month.
It felt wonderful; also I have heard of people doing it (cutting hair) often, due to extreme unhappiness or stress.
For me, I was happy at that time...to have short hair, as time went by I let it grow....but that was some time.
I do not agree about women with short hair are damaged.
That to me is too much of a broad-statement.
