Always consult your doctor to discuss potential underlying causes and health issues. There are some correlations between low vitamin D levels and hair loss, but there have been no conclusive studies to date. While people with hair loss have tended to have lower levels of vitamin D, this is not evidence in itself. Approximately 40% of the population is vitamin D deficient, and most of them are asymptomatic. A simple blood test can determine your vitamin D level and your physician can recommend a course of action to remedy it.

Vitamin D is an essential nutrient that plays a role in many of the body’s functions. While anybody may be uncomfortable in the cold now and again, if this feeling persists or your sensitivity is extreme, you should promptly contact a healthcare provider to find out the cause. Certain medications, such as proton pump inhibitors (PPIs) (taken for acid reflux), metformin (taken for type 2 diabetes or insulin resistance), or nitrous oxide (an inhaled anesthetic), can deplete your B12 levels. According to Michon, you will likely get a good amount of vitamin D through natural sunlight even if you are applying sunscreen regularly because, again, sunscreen application is never perfect. Currently, there’s not enough evidence to show that sunscreen decreases vitamin D concentration, and researchers believe that it doesn’t cause vitamin D deficiency. As long as the vitamin D deficiency is not too severe, a change in diet can bring about the first positive changes.

Moreover, exogenous biotin interferes with some laboratory tests, creating false negative or false positive results. There are a few studies addressing the relationship between hair loss and folic acid or vitamin B12, but the lack of extensive studies precludes any recommendation for vitamin B12 or folate screening or supplementation. Hypervitaminosis A causes hair loss, and data on the effects of isotretinoin in hair loss support this association. Goette et al. described nine patients who developed TE after 2–5 months of starting a vigorous weight reduction program and losing 11.7–24 kg. It was thought that rigorous caloric restriction with subsequent inadequate energy supply of the hair matrix might be the cause for the precipitation of TE of the crash dieter [133].

If you’re concerned about your vitamin D intake, ask your doctor about checking your vitamin D levels. When you get the recommended daily amount of vitamin D, you’re able to maintain hair growth, bone health, and normal calcium breakdown. Vitamins and minerals play a pivotal role in regulating hair growth and maintenance, with deficiencies linked to increased hair loss through various pathophysiological mechanisms. Essential nutrients are critical for the proliferation of hair follicle cells, and their deficiency can disrupt the hair growth cycle, leading to the miniaturization of follicles and eventual hair loss. Studies have found a strong link between vitamin D deficiency and alopecia areata—an autoimmune disorder where your cells mistakenly attack hair follicles. In one study, scientists tracked 86 people with alopecia areata and found that they all had "significantly lower" vitamin D levels than people without the condition.
The optimal daily dose of vitamin D for adults up to 70 years old is 600 IU (or 15 mcg). The amount of vitamin D you need will depend largely on how deficient you are in the vitamin, so it's best to consult your doctor for a tailored recommendation.

Prevention
The mean serum 25-hydroxyvitamin D [25(OH)D] level in patients with AA was significantly lower than that in the non-AA control group, by 8.52 ng/dL (95% confidence interval − 11.53 to − 5.50 ng/dL). Vitamin D deficiency was also highly prevalent in patients with AA, leading the authors to suggest that the vitamin D level has to be measured in patients with AA. These results also suggest that vitamin D supplements or topical vitamin D analogues should be considered for patients with AA and vitamin D deficiency.
Symptoms of vitamin B12 deficiency
Some people have a gene variant known as MTHFR that keeps them from making the active form of folate needed by the body. People who have had stomach surgery, including some types of weight loss surgery that removes all or part of the stomach, may also not be able to absorb enough vitamin B12 from the diet or oral supplements. A deficiency can be caused by an autoimmune condition known as pernicious anemia. With this, your own immune cells attack your stomach, making it unable to absorb B12 as it should. While sunscreen can block UV rays, Michon says that in many cases, people fail to cover all of their skin when applying sunscreen or forget to reapply every two hours, as suggested by the American Academy of Dermatology. In these situations, people are likely getting the vitamin D they need, either from an unprotected patch of skin or because the sunscreen has worn off.
You're unique. Your supplements should be too.
Exposure to the sun for ten to thirty minutes per day is supposed to be enough for your body to create sufficient amounts of D, but this isn’t always true. Nearly 40% of the population are vitamin D deficient or have low levels and may not present with any symptoms. It is important to check your levels periodically and if necessary consult with your physician about the best possible options to bring your levels within the normal range.
It is therefore important to consider what form of vitamin A is contained in supplements (provitamin A carotenoids or preformed vitamin A) and in what proportion. People commonly inquire about vitamin and mineral supplementation and diet as a means to prevent or manage dermatological diseases and, in particular, hair loss. Answering these queries is frequently challenging, given the enormous and conflicting body of evidence that exists on this subject. Hair loss is a common problem that may be improved with vitamin and mineral supplementation. Vitamins and minerals are important for normal cell growth and function and may contribute to hair loss when they are deficient. While supplementation is relatively affordable and easily accessible, it is important to know which vitamins and minerals are helpful in treating hair loss.
For this reason, vitamin D deficiency is a very common problem worldwide. Vitamin D is abundant in many foods, including fatty fish like salmon and tuna, cheese, eggs, and fortified milk. Adding these to your grocery list can help keep your nutrient levels up without having to rely too heavily on supplements. Your first line of defense against vitamin D deficiency hair loss is supplementing with an oral dose. This is the quickest and most efficient way to get your nutrient levels up, but make sure you're taking a safe amount to avoid toxicity. Talk to your doctor to determine the proper dosage for your age and body weight.
In addition to checking vitamin D levels, your doctor will be able to check iron levels and blood counts and examine your scalp to see if anything else might be at play. That might sound positive for your hair, but consuming too much vitamin A can actually cause hair loss. Sometimes, hair loss can be caused by getting too much of a certain vitamin or mineral. Hair loss is not a typical symptom of magnesium deficiency, but some research shows that supplementing with magnesium can help with hair loss in women with polycystic ovary syndrome (PCOS).

When deficiency disrupts vitamin D in your scalp, the anagen (growth) phase shortens.
