Vitamin D is metabolized in the skin by keratinocytes. These are skin cells that process keratin, a protein found in hair, nails and skin. When the body doesn't have enough vitamin D, the keratinocytes in the hair follicles have trouble regulating hair growth and loss. Can vitamin D supplements help with hair loss? It depends on whether the hair loss is due to a vitamin D deficiency.
According to Chacón, “a laboratory analysis of hair loss should include tests to assess current levels of vitamin D. The good news is that hair loss due to vitamin D deficiency is often reversible. Once vitamin D levels are increased, hair follicles will normally begin to function properly and hair will begin to grow again. New hair growth can take several months to become visible, so be patient while you wait for the results.
Vitamins for hair growth, such as vitamin D supplements, are said to help curb alopecia and baldness to some extent. Vitamin D deficiency is thought to cause certain types of hair loss problems, such as alopecia areata and male pattern baldness. Low levels of vitamin D may be associated with a poor hair growth cycle, which can lead to slow growth, which could exacerbate hair thinning and the appearance of bald spots. Vitamin D supplementation is a good solution for restoring ideal hair health, but it may not be sufficient to treat the symptoms of serious hair loss problems.
Low vitamin D levels are also related to certain forms of hair loss, a topic we'll discuss in more detail below. Another study was similarly successful, and researchers found that a topical treatment with vitamin D was effective for hair loss in nearly 70% of the study participants. But be sure to consult your doctor first about the best treatment options for hair loss caused by vitamin D deficiency. While the precise role of vitamin D in hair growth is not well understood, more research from the National Center for Biotechnology Information shows that vitamin D receptors play an important role in the anagen phase of the hair follicle cycle, the phase in which new hairs grow from the follicle to their full length.
Vitamin D supplements may work best for hair restoration when taken in conjunction with appropriate hair loss treatments. In one study, a 45-year-old woman diagnosed with diffuse hair loss was treated with vitamin D supplements for three months. Research has shown that people with vitamin D deficiency often experience some degree of hair loss. While more research is needed to determine exactly how vitamin D affects hair growth, there is some evidence to suggest that it may play a role in maintaining hair follicle health and keeping the hair growth cycle going.
A study found that women who were deficient in vitamin D were more likely to suffer from hair loss than women who had sufficient levels of vitamin D. It is generally believed that the longer a person is deficient in vitamin D, the more likely they are to suffer from hair loss. However, overuse of vitamin D supplements can cause something called vitamin D toxicity, a potentially harmful condition that can lead to nausea, vomiting, constipation, weakness, weight loss, reduced appetite, heart rate problems, and even kidney damage. .
