Hi Doc,
I am wondering if there any current links between supplementation of Vitamin D and potential hair issues. I am looking to try to minimize my acne and supplement with 2000 IU Vitamin D daily.
I also found an old study dating to 1937 entitled “Vitamin D in Acne” [PDF file]. In the study, I noticed a mention that “Three patients with alopecia areata grew their hair without other treatment” except supplementation with Viosterol (pre-Vitamin D). Is this method ever used today to ever treat hair disorders??
Thanks

The thing about alopecia areata is that even with NO treatment, the hairs usually grow back in a substantial number of patients, so I really cannot comment on the 3 patients that grew their hair back.
I do not know of any vitamin or pre-vitamin treatments for hair loss that works, and I suspect that in the 74 years since that study was conducted, if there was some actual evidence that it worked, it would be a common treatment by now.
