Personally, I don't think younger generation is as concerned. I would think the same applies to something simple as glasses. My age bracket and probably older, there was a slight negative connotation towards glasses i.e., "four eyes", etc. However, I don't see that in the the younger crowds. They are pieces of accessories.
I personally think, the sample probably applies to hair as well. We are starting to lose our hair younger and younger from various factors and I am starting to see more balding ("M" shaped hairlines) pictures/models used. There are people here who, I think are simply deluded into thinking balding is not sexy. Sure not the best thing in the world but clearly there is more to life and yes, you can still get laid if you are bald. Just play your cards right.
