I take your point UCMan about a bald head attracting more looks, although Islander only has some crown thinning not a full blown, slick bald head.
I think like Finasteride and Minoxidil side effects, some of the perceived negative reactions to baldness in public are imagined...
Now before you all bite my head off, I'm not saying it doesn't happen, I know it does myself and I'm only a NW3, I've had shopworkers openly take the p*ss, suggesting I buy a winter hat and I've had female barmaids take my order than look at my hairline with revulsion and disgust.
Sometimes however I think we can get carried away with this though, thinking every person having a laugh in public or grinning to themselves as they walk down the street is having a joke on us... I was in this situation last summer, having lost my job and lost my flat I was suffering from major depression and because my self esteem, confidence and self-worth was total rock bottom, I just assumed EVERYONE in public was laughing at my hairline...
But in reality that person laughing in the street is almost always laughing about something completely diferrent, their own private joke with their friend, likewise the guy walking down the street grinning as he passes you by, is most likely laughing to himself about a joke his friend told the other day (I know I do this myself all the time!)
Yes you will get a sad, pathetic few people who will take the p*ss in public definitely, but at the same time I think it's very easy to get over paranoid (almost delusional in my case) and imagine lots of bad public reactions which aren't actually there, especially if you step out the door with zero self-esteem, thinking you like like a total freak. The mind plays an important part here.
