Umm... dude. Wut?
I don't see baldness as a disease.
I see it as variety.
That's a little like blue/green eyed people saying brown eyes are a disease because more people prefer light ones.
Or men who prefer all women to be smooth and hairless(neck down) women seeing "excess" natural hair below the chin as a disease. Some women are just more hirsute than others. It doesn't mean she needs drugs...
It makes the world a more beautiful place.
There is someone for everyone.
