Definitely not though it is something that, over the years, my friends have talked about.
I had long one side and short the other years before it came into fashion and my friends used to think I was quite crazy!
I do not think hair is a womans crowning glory, and I have not heard that long hair symbolises strength!
You live and learn.
Yes, the Sikhs believe that a man should never cut his hair as it represents his strength as a warrior and in the Old Testament Samson had enormous strength but only for as long as he kept his hair uncut, so his enemies got Delilah to seduce him then cut his hair when he was asleep.... two very different religions and cultures but both with the same (slightly bonkers IMHO!) idea.
