there's also trying to avoid being treated worse because of baldness. I think it's easy to be dismissive of this, and of course there are worse things, but nonetheless I think it's a real issue.
That's definitely a thing, when you go bald you will definitely be treated differently.
For a concrete example of this just look at TV shows and movies and compare the number of bald lead actors to the number of bald people you know in real life. You could argue over the percentage of men that are bald but you'd still be arguing over a significant percentage.
Where as you can probably name ALL of the famous bald actors without trying.
I'd bet that dating sites would also be able to extract some interesting data too.
It's much hard to extrapolate that other areas of life such as job interviews (obviously bald people have jobs where appearance is less important that skills or experience) but personally I'd guess there is still an effect that can be measured.
