Vitamin D Deficiency and Hair Loss
Does Vitamin D Deficiency Cause Hair Loss?
To the very best of my knowledge, there is no known link between hair loss and vitamin D deficiency. By that, I mean that I am not aware of any conclusive scientific research associating the two.
I searched the two terms in both Bing and Google, but the majority of the results were from Q&A forums and consisted largely of questions like the one you’re asking. There was nothing of relevance in the Google News results for the phrase ‘vitamin d deficiency hair loss’.
That is not to say that vitamin D deficiency does not bring about hair loss, merely that if science has determined that the former precedes the latter, I haven’t seen the evidence or the proof despite actively searching for it.
The truth of the matter is that I wouldn’t be the least bit surprised if in fact hair loss is a symptom of vitamin D deficiency, and that one day science establishes and then confirms that the two are in fact related.
I did a post on this particular nutritional deficiency several weeks ago. While researching the topic for the post, I learned of well over 20 different diseases and ailments that had been scientifically linked to vitamin D deficiency. Since I published that particular article, I have learned of several more that weren’t on my original list, putting the number at close to 30.
All that said, until further notice, the answer to the question is “no”, at least for the time being. There is simply insufficient evidence at this point linking vitamin D deficiency to hair loss and/or premature balding in men. Perhaps in the future there will be, but for now there is not.
In any case, vitamin D deficiency leads to so many diseases and other health problems and vitamin D3 offers so many important health benefits that it would be wise to make a point of taking a daily vitamin D3 supplement regardless of whether or not it impacts hair loss and/or balding.
