Getting a hair transplant carries a stigma in society, so "accept" could use some qualifiers.
People don't get murdered for getting hair transplants & people getting hair transplants aren't being targeted politically, so considering the scale of stigmas associated with gender affirming care, no, I don't think it does.
I think you've added context that I didn't write. I'm not saying it's as "unaccepted" in society as, say, HRT for transitioning. Just that it's not accepted and is still a point of derision.
I've never heard of this stigma myself, can you explain
