Actually, I am of the shaved head camp and on recent lab work noted low vitamin D levels (25OH D2, 25OH D3 and 25OH VitD total) . Of note, I do wear a cap more often than I used to prevent excessive cranial cold or burn.

“We found no evidence to support the hypothesis that the degree of baldness in men influences serum 25-OHD levels.”
Does degree of baldness influence vitamin D status? Mark J Bolland, Ruth W Ames, Andrew B Grey, Anne M Horne, Barbara H Mason, Greg D Gamble and Ian R Reid

I realize that there has been studies of vitamin D levels in humans comparing northern to southern climes but what about comparing hirsute to less hirsute individuals?

Subject: More on vitamin D in furry animals
For an obscure reason, I was recently in discussion with a national camelid expert from the Royal Vet School about the measurement of vitamin D. Apparently Vitamin D deficiency is well described in llamas and alpacas in Europe but not so in their S American ancestors/relatives – the guanacos and vicuòas. The main site of vitamin D synthesis is around the nose and ears (large and long respectively) where the hair is shorter, but come transfer to northern climes ……… Clinical rickets is seen in the young (crias) and supplementation advocated. A subject of much debate by our vet colleagues.
Guanacos have other adaptations to a dry (water not EtOH) life such as spherical red blood cells and extra bits of colon.
Seasons greetings.
