My bf started losing his hair in his early 20s and the effect it's had on him is devastating.
He's an actor and he was dropped by his agent after he stopped hiding his hair loss. The roles he was cast in narrowed and shifted from more heroic characters to villains, and eventually he became so miserable about it that he stopped going to auditions altogether.
He used to enjoy dyeing his hair bright colours, and he lost that means of self expression. It alienated him from his own appearance, which knocked him back in coming out and exploring his queerness. The way he talks about it often feels dysmorphic. He says shaving makes him feel like he's "rotting" - like he's "scraping the mold off [his] head".
I've seen drunk people and teenagers yell at him in the street and mock his baldness. I've seen people come up to him and slap his head or touch it without asking for permission. I've witnessed this behaviour from other trans people and women who I know would absolutely kick off if he took such a degrading or entitled attitude towards a part of their body, but seem to think it's OK to do it to him.
Since going bald people perceive him as more masculine. He feels people are more suspicious of him. Women are less likely to approach him. Folks are quicker to put him in a box or misread his behaviour as aggressive or threatening, when the reality is that he's neurodivergent and can't conform to rigid social norms.
Baldness is a heavily gendered characteristic. If someone is conventionally masculine enough and/or is protected by other intersecting powers and privileges (eg wealth) then baldness can reinforce their maleness and the harm to their social standing is minimised. But if their performance of maleness is complicated by something like queerness or disability, it creates a dissonance. They have what is perceived as a hypermasculine trait standing in sharp contrast with their refusal/failure to perform normative, idealised masculinity.
And that's how baldness is typically read - as failure. Especially when it exists outside of wealthy, successful, heterosexual masculinity but tbh even there too - just look at all the jokes about Jeff Bezos' baldness or Elon Musk getting hair plugs. It's similar to insulting Trump over his weight. Like yeah fuck those guys but all you're really doing is revealing to the fat and bald people in your life that you think their bodies are deserving of mockery.
And God help you if you're a bald woman. All women with receding hairlines are at a huge risk from transmisogyny.
Sorry for the essay. Baldness is absolutely a body neutrality issue. It's an ageism issue, and a trans issue, and I WISH there was a broader recognition of this.
