You have one anecdote of a situation where you know nothing about the girl nor the dynamics of their relationship, and I can show you countless others where the opposite is true. I noticed you conveniently left out your Norwood and responding to my request to try dating while bald for yourself, I guess you won't do it because, well, why do it? It would be an unpleasant experience and we all know it.
Again, you can improve all other aspects of your life. If you are out of shape, you can get in shape. If you are short, well, as long as you are not too short you will be fine. Most girls are shorter than guys anyway and as long as you meet the equal or taller criterion, you're all good.
"But that doesn't mean that if you are bald you will have problems. there will be problems with your way of thinking."
No, it means exactly that. You will have problems. Again, I invite you to try it out for yourself. Looksmax everything else, start lifting everyday, buy expensive clothing, do whatever you want to do.
You can overcome these problems. You can fake confidence as well. Fake it till you make it can work. But things will be significantly harder. Your odds become slimmer and slimmer. Odds are just odds, probabilities that may go your way or not, and with enough effort, they can be overcome.
The point still stands that your dating life just became much more difficult no matter how else you try to compensate.
Remember, I'm eager to be proven wrong. As a high Norwood I want you to be right. To see evidence of you being right would be a great thing for me and many high Norwood guys out there.
