This may not be the reply you expect, but bear with me.
One of my girl friends as a child suffered alopecia, totally bald! She was at turns self-conscious about her condition, and at the other extreme very capable of shrugging off the worst abuse. In her early teens she was still learning about human cruelty and facing it head-on. Obviously women were expected per religious and social tradition to have long hair, but she chose a short wig, and when some horrid boy ripped it off her head one day, she joyously proclaimed, "Thank god, that thing was making me hot!" Little did she know that her humorous resistance to juvenile cruelty made her all the more attractive to boys like me. We lost touch, but this was the imprint she made.
Fast forward to my twenties, thirties, *cough* wot-have-you.....

and a mate or three wot suffered the gene that left him follicly challenged ( as opposed to me ), and perhaps one found their gender fluidity. My opinion is that masculinity isn't defined by a full head of hair, and neither is femininity. I admire a slave, no matter their genitalia, who embraces their flaws and hales a hearty FUCK-YOU to bullies. That is beauty and character.
