Okay, I'm mtf (just starting hrt, with very long hair)
How long are some of you guys talking?
In my experience, shoulder length, they will mostly ignore. Anything more than your shoulder blades and people will really start to talk and look at you strange, of course age, job and a few other things my effect this as well. At this length it also becomes a hassle, but some of you are probably aware of that.

My hair has been the topic of more than a few conversations behind my back. I have had some strange comments made and a few people have actually threatened to cut my hair off. Men think it's strange and not appropriate for business and old ladies just seem to really have issues with it. My great grandmother would disown me if she saw my hair even half the length it is, she complained as a child if it went close to my shoulders. It's at my waist now. Some just think it was a reaction to getting out of the military and being forced to have short hair so they often do not bother me about it (hehe, I was always out of regs). Some don't want to mention it, others are downright rude but it always causes a commotion these days.
