Does having a vitamin D deficency cause hair loss? I’m a 26 yr. old female and I’ve been going through what the Doctors are calling TE. After all the blood work, my iron levels were just below normal, but the more alarming results were my vitamin D levels. I was wondering if you thought a vitamin D deficency could result in hair loss?

Some researchers believe that vitamin-D regulates the expression of genes. When scientists knocked out those genes in mice, the mice displayed vitamin D deficient symptoms of rickets and hair loss. Correcting vitamin-D makes sense if you believe you are deficient in vitamin-D. Check with your doctor about how to manage the process.
