Vitamin D is needed to help keep your muscles, bones and teeth healthy, according to the NHS. If you don’t get enough vitamin D in your diet, it’s difficult to regulate the amount of calcium or phosphate in the body. A severe lack of vitamin D can even lead to some other complications, including deformities, rickets or osteomalacia. Vitamin D is used by the body to help with the hair growth cycle, which may be the cause behind the link.
While more research is needed, it’s still best to make sure you have enough vitamin D in your diet, said the clinic. “There have been numerous studies into the effects vitamin D has on our general health, most notably it plays a vital role in bone health and the prevention of cardiovascular disease and diabetes.
However, recent studies have also found a link between vitamin D and hair loss, namely whether having a vitamin D deficiency can result in hair falling out. The most recent study looked at women with hair loss, and does indicate that those women experiencing hair loss had much lower vitamin D levels than normal.
