Recently 1 month back, I have developed a alopecia areata patch in back of my head. I tried to check my vitamin level and found that I am vita min d deficiency. Vitamin d2 - 2 ng/ml, vitamin d3 - 6.07 ng/ml, vitamin b12- 252 pg/ml, vitamin b1-1.2 ng/ml, vitamin b2 -11.52 ng/ml, vitamin b3 - 2.93 ng/ml, vitamin b5 -98.05 ng/ml, vitamin b6- 15.54 ng/ml, vitamin b7 - 1.07 ng/ml, vitamin b9 - 0.98 ng/ml, vitamin k - 0.24 ng/ml, vitamin e - 13759 ng/ml, vitamin a - 416.75 ng/ml, I was wondering if my alopecia is because of my vitamin d deficiency?
