I would love to read a an actual study on this. The article from this link doesn't mention that AA is an autoimmune disease. As Wise has stated there is a link between V D and autoimmune diseases but no real connection to hair loss.
As it happens I saw my family doc today. result of a current VD test was borderline low...pretty standard living in Toronto. She said no more then 1000 iu daily. not a good idea to take more.
