Vitamin D supplements are a great way to improve vitamin D blood levels. Unfortunately, there aren't many foods that naturally contain an adequate amount of vitamin D. If you keep taking your vitamin D supplements, you'll likely see the results of hair regrowth within six to eight weeks. The good news is that hair loss due to vitamin D deficiency is often reversible.
Once vitamin D levels are increased, the hair follicles will normally begin to function properly and the 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. Vitamin D is best taken daily, either as a supplement or by exposure to sunlight. If hair loss is due to a vitamin D deficiency, taking a supplement or increasing exposure to sunlight may help.
While vitamin D deficiency can cause hair loss, there are other factors that can also contribute to this condition. However, treatments such as minoxidil and finasteride can help slow the progression of hair loss and improve the appearance of weakened hair. Vitamin D is mainly absorbed through exposure to the sun, but you can take dietary supplements and eat certain foods to increase your intake of the nutrient. Exclusion criteria included topical treatment with vitamin D3 compounds or systemic therapy (phototherapy) during the past month, the use of vitamin D3 supplements and other chronic inflammatory diseases, such as multiple sclerosis, inflammatory bowel diseases, rheumatoid arthritis, insulin-dependent diabetes mellitus, systemic lupus erythematosus, lymphoma, non-melanoma skin cancer, or any history of cancer.
However, anecdotal evidence suggests that hair may stop falling out and regenerate as little as two months after treatment. The Pearson chi-square test showed no significant difference between the three categories of vitamin D in both groups (P %3D 0.5). Vitamin D deficiency has been linked to alopecia, also known as localized baldness, and to several other health problems. Extensive studies in animal models show that VDR plays an important role in the hair follicle cycle, especially in the anagen phase.
Vitamin D deficiency is a treatable condition, and if it's the cause of hair loss, increasing levels can help stop or prevent further 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. But be sure to talk to your doctor first about the best treatment options for hair loss caused by vitamin D deficiency. Your doctor can test you for vitamin deficiencies and other conditions that may be causing hair loss.
Following a healthy diet of foods that naturally contain vitamin D or are fortified with vitamin D can improve your levels. Individual variables are factors that affect serum vitamin D3 levels, such as age, weight, skin type and exposure to the sun.
