Hi! I have visited another doctor to consult about my condition. Actually I don't really have a "serious" symptomps. The problem that bothers me the most is hairloss, and sometimes I got very tired and headache, also burning head or scalp. He suggested me to have vitamin D tested. I also checked for allergic. The result is I got 17 ng/mL, which the standard should be 30-100. I take vitamin D about 2000 IU/day now. I want to know if you have vit D deficiency and your experience about it. I also read that vit D also good for hair and skin, and it is a prohormone that linked to autoimmune. I hope this could be solution for my hairloss.
