Same for me on the cultural acceptance. Though, I was very hesitant to bite the bullet and shave my head completely. I just know that even for me, it was somewhat stressful to have random parts of my hair go missing. Doesn't help that I rarely look at myself in a mirror, so I wouldn't even always know when I was missing more hair. Would just get the occasional, "why did you shave right above your ear?"
Nowdays, though, it is just funny. My legs have spots where I have lost a lot of hair. Some folks assume it is because I bike. Explaining that I will likely lose all of my hair is one that I don't think most folks believe.
At any rate, if it were stressful for me, I can only imagine it would be worse for my daughters. Luckily, to date they have had absolutely none of my difficulties growing up. No allergies or anything.
I completely understand your concern about your daughters. I'm lucky that baldness is culturally accepted for adult men (and even encouraged), so I don't feel too self-conscious about alopecia. Hopefully we'll get a better handle on autoimmune conditions with this new class of drugs. Until then, organizations like NAAF (http://www.naaf.org/) are wonderful in helping people with alopecia cope with its medical, emotional, and psychological impact.
