This is a great topic Melvin. For me personally, it had a huge effect on my confidence. I think in part with dating in a large city like Chicago, it's a "competitive market" so you want to be on your A game as far as appearance is concerned. Like others have stated, dress and personality are things I used to compensate and did find some success with it.
Though after my transplants, my confidence has gone way up and there has definitely been more matches for sure. I think it's a case by case basis with some guys who don't mind shaving their heads versus us who seek a full head of hair. Personally hearing when something compliments me on my hair or facial features as a result of the illusion of how you're face is more well framed is priceless to me.
