I cut my long hair about 8 years ago and never looked back. My wife often laments the loss but, oh well, short hair is so much easier to maintain, and wash, and comb, and cut.
I did not notice a difference in the way I was treated, but I went from 18 inch long curly hair to shaved bald. People still looked down on me because of the way I look. Even earlier this year I had a 6 inch goatee with shaved head and people still look at me weird.
