Subject: Is alopecia universalis' frequency increasing and is it a sign of evolution

I hesitated before selecting the area of science in the light of which I'd like 
to get my question answered : it actually belongs to several categories at the 
same time : medicine, genetics, and evolution, at least.
Is the frequency of alopecia universalis increasing and can it be regarded as a 
sign of evolution of our species ? Is it ludicrous to imagine that AA could 
become the norm within a few thousands years (not to mention other changes, in 
average height, body proportions, skin hue and skull shape for instance)?
