This may also be particularly helpful during the winter months or for those populations listed above who are at an increased risk of deficiency. Also there is evidence that sunlight can cause the release of nitric oxide from the skin (21). Nitric oxide is a vasodilator that can reduce blood pressure and in the scalp may improve blood supply. Telogen effluvium is identified as a very common cause of diffuse hair loss by the Journal of Clinical & Diagnostic Research (19). Vitamin D is understood to be one of the most important nutrients required for the body to function optimally and for an individual to be healthy.

Vitamin D-related hair loss typically grows back once vitamin D levels are restored to healthy levels. How long it takes for vitamin D to improve hair loss depends on many factors, including how long the vitamin D deficiency has been present, supplementation dosage, age, and severity of hair loss. Research shows that vitamin D supplementation can correct deficiencies and may be an effective hair loss treatment for various vitamin D-related hair disorders. Overweight or obese individuals typically require higher amounts of vitamin D to support adequate blood levels. Vitamin D is stored in fat cells, and large amounts of body fat trap active vitamin D, lowering blood concentration levels and impacting vitamin D-regulated pathways. Almost all cell types in the human body have vitamin D receptors, indicating that vitamin D regulates normal cell function throughout the body.

Maintaining homeostasis—and by extension the proper concentration of active metabolite—is important for healthy hair [18]. The role of nutrition and diet in treating hair loss represents a dynamic and growing area of inquiry. In this review we summarize the role of vitamins and minerals, such as vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, iron, selenium, and zinc, in non-scarring alopecia. Iron is important for having healthy red blood cells, which carry oxygen throughout your body. If you don’t get enough iron from your diet, you can develop anemia, or a low red blood cell count, which is a cause of hair loss. Research shows correcting a vitamin D deficiency can help promote thicker, healthier hair growth.

Some of the causes for this condition can be deficiency of certain vitamins. These symptoms are not unique to vitamin D only and if you have any health concerns or notice any of these symptoms you should always talk to your doctor. Your team can come up with the best plan to address your concerns that are unique to you and your needs.

Vitamin D and AA
Since a child’s bones are still growing, demineralization causes bowed or bent bones. While reference ranges can vary, the National Institute of Health (NIH) suggests that levels of 50 nmol/L and above reflect adequate vitamin D levels for most people. Vitamin D deficiency is surprisingly common, but the symptoms are often subtle and nonspecific, so it may be hard to know whether you have a deficiency or some other health condition. It can be difficult to tell whether you have a vitamin D deficiency, as the symptoms may be subtle. Furthermore, it’s possible to have a vitamin D deficiency without experiencing any symptoms.

However, some people may have vitamin D deficiencies because of another underlying condition, including Crohn’s disease or celiac disease, which prevent the body from fully absorbing nutrients. In this article, we look at how vitamin D and hair growth are connected, if a deficiency causes hair loss, and if it is reversible. If your hair receives all necessary nutrients, it will look shiny, healthy, and appealing. Thus, start your hair care with adopting a healthy diet or taking carefully selected supplements.

In addition, a few case reports have been published relating TE with crash diet [134–136]. Venton et al. described the loss of pigmentation of the hair in four patients receiving TPN without selenium supplementation. The serum and hair selenium levels were 38 ± 11 ng/mL and 0.34 ± 0.13 μg/g, respectively. Hair started to re-pigment after 6–12 months of therapy with intravenous selenium [117]. Similar findings, including alopecia with pseudoalbinism, were found in 6 infants receiving nutritional support. In these six infants, after starting daily selenium therapy (5 μg/kg/day), selenium serum levels returned to the normal range of 5–15 μg/dL, and alopecia and pseudoalbinism improved [118].
This leads to secondary hyperparathyroidism (overactive parathyroid glands attempting to keep blood calcium levels normal). Vitamin D deficiency is common and has been linked to disrupted hair follicle cycles, hair loss, thinning hair, and baldness. The amount of time required to treat vitamin D deficiency depends on your age, the severity of the deficiency, and any underlying health conditions. A healthcare professional may prescribe adults vitamin D supplements like cholecalciferol for up to 10 weeks, while children may receive a prescription for 12 weeks. Some ways to help you increase your vitamin D levels include getting more sunlight, taking vitamin D supplements, and consuming more fatty fish. Similarly, a 2018 study in 98 adults with lower back pain linked lower levels of vitamin D to more severe pain.
Some research shows that selenium can help with hair loss, including among people who are getting chemotherapy. Unfortunately, there aren’t many clear-cut answers when it comes to which vitamin deficiencies cause hair loss. However, this article will cover what we do know about vitamin deficiencies and hair loss, as well as what nutrient intakes can impact your hair. If a vitamin D deficiency is confirmed, the good news is there are effective remedies.
Zinc is an essential trace element, which means that the body cannot generate it on its own; it must be supplied through the diet. Alcoholism, malignancy, burns, infection, and pregnancy may all cause increased metabolism and excretion of zinc. Management of alopecia is an essential aspect of clinical dermatology given the prevalence of hair loss and its significant impact on patients’ quality of life. Androgenetic alopecia (AGA), telogen effluvium (TE), and alopecia areata (AA) represent the three most common types of non-scarring alopecia [9]. There are several reasons to suspect a role for micronutrients in non-scarring alopecia. The most noteworthy of these is that micronutrients are major elements in the normal hair follicle cycle, playing a role in the cellular turnover of the matrix cells in the follicle bulb that are rapidly dividing [10].
While hormonal changes, alopecia, tight hairstyling, overusing hot tools, and environmental factors are among the most common causes of hair loss, vitamin deficiencies can play a role as well. Most adults shouldn’t consume more than 10,000 international units (IUs) of vitamin A daily. If you’re supplementing with vitamin A and notice hair loss, talk with a healthcare provider. Your doctor will advise on the dosage needed to restore your vitamin D levels to the optimal range.
The authors found that there was no significant association between dietary, supplemental, or total vitamin D intake and risk of developing AA [69]. Stress is linked with some types of hair loss including alopecia areata and telogen effluvium. While vitamin D may play an important role in treating some cases of hair loss, it’s not the only nutrient linked with healthy hair. Remember that sunlight is also a good source of vitamin D, and excessive use of sunscreen because of skin cancer concerns is likely a big contributor to chronically low levels of vitamin D among the population. You can also get vitamin D by eating more egg yolks and omega 3-rich fatty fish such as salmon and mackerel, which is also a useful anti-inflammatory food.
Can vitamin D deficiency cause hair loss is the specific question we’re going to consider in this article. But we’ll also look at the topic within the wider context of diet and lifestyle tips for healthier hair, plus why preventable hair loss might occur. However, not getting enough iron and developing anemia can cause hair loss. Unless you have a deficiency in a certain vitamin, supplementing with vitamins likely won’t do much for hair loss.
Because of this link, getting adequate amounts of vitamin D can support hair growth and regrowth. If you are sensitive to the cold, it's important not to discount this symptom by simply wearing extra layers or changing your environment. Your system may be off due to a deficiency or condition that doesn't allow your metabolism, circulation, or blood vessels to function properly. Alcohol use disorder, having undergone intestinal surgery, or having a digestive disorder can interfere with folate absorption, and you may develop a deficiency.
