An estimated 42 percent of Americans are deficient in vitamin D. Even more interesting, in a 2007 study from the US National Library of Medicine, nearly 53 percent of Caucasian women, 94 percent of non-Caucasian women, and 100 percent of African-American women participants were found to be vitamin D deficient.<\/p>\n\n\n\n
The relationship between vitamin D and hair loss:<\/strong><\/p>\n\n\n\n Our bodies need vitamin D (and other nutrients) for healthy bones, skin, and hair. If we aren\u2019t getting enough, we\u2019re at increased risk for many health problems, including hair loss. Some of the most common conditions linked to vitamin D deficiency include:<\/p>\n\n\n\n Telogen effluvium, a condition in which hair falls out as a response to stress. Alopecia areata, an autoimmune hair loss disorder most commonly found in women under the age of 30 and Female pattern baldness.<\/p>\n\n\n\n The relationship between vitamin D and hair growth:<\/strong><\/p>\n\n\n\n Just as vitamin D deficiency has been linked to hair loss, having the right amount of vitamin D in your body has also been linked to hair growth. In fact, a 2012 study in the journal Stem Cells Translational Medicine suggests that vitamin D may actually help create new hair follicles and stimulate existing follicles that have become dormant.<\/p>\n\n\n\n If you\u2019d like to supplement your diet and support hair health with vitamin D supplements, talk to your doctor first to find out how much is right for you. Although rare, too much vitamin D can lead to nausea, vomiting, poor appetite, stomach pain, and constipation or diarrhea. Excessive doses of vitamin D may also lead to bone loss and kidney failure.<\/p>\n\n\n\n
