Despite the wide availability of hair products enriched with vitamins and minerals for hair, true health of your locks starts from within. Thus, if you have noticed that your hair is falling out beyond its norm, it is time to analyze what vitamins you are lacking to optimize your nutrition or select supplements for hair growth. Feeling cold when others do not may be linked to a lack of certain nutrients, such as vitamin B9, vitamin B12, or iron. A deficiency in any of these can lead to a lack of sufficient healthy red blood cells to transport needed oxygen to all areas of the body. The main source of vitamin D is exposure to solar UVB radiation (from sunlight). 4 When the body is exposed to sunlight, it can manufacture vitamin D from cholesterol, a fatty substance synthesized by the liver and found in some foods.
Role of vitamin D in hair loss: A short review
Murine hair follicle keratinocytes are immunoreactive for VDR, showing their highest activity in the anagen stage [61]. The role of vitamin D in the hair follicle is evidenced by hair loss in patients with vitamin D-dependent rickets type II. These patients have mutations in the VDR gene, resulting in vitamin D resistance and sparse body hair, frequently involving the total scalp and body alopecia [62–64].
Who is most at risk for vitamin D deficiency?
When UV radiation penetrates through your skin, your body transforms a precursor of vitamin D into vitamin D3. Then, the liver converts that molecule into another type of vitamin D called 25-hydroxyvitamin D (calcidiol). And finally, the kidneys transform it into 1,25-dihydroxy vitamin D or (calcitriol), which is the active form of vitamin D.
Other Common Causes of Hair Loss
Aging, hormones, stress, and inflammation are all factors that contribute to hair loss or a receding hairline. However, your nutrient status, including whether you have sufficient levels of vitamin D, is also thought to have a bearing on hair health. Research shows that a lack of vitamin D in your body can lead to hair loss. When there isn’t enough vitamin D in your system, new hair growth can be stunted. Essential fatty acids, such as Omega-3, regulate our body’s natural functions.

Role of Micronutrients in Scalp Scaling Conditions
These researchers found no significant difference in folate and vitamin B12 levels between patients with hair loss and control patients [35]. Ramsay et al. reported a reduction in vitamin B12 levels in females with AGA treated with ethinyl estradiol and cyproterone acetate (Diane/Dianette and Androcur). This reduced vitamin B12 level resulted in vitamin B12-related anxiety, causing some patient to stop treatment. However, a daily 200 µg vitamin B12 supplement corrected the reduced B12 concentrations.

However, specific conditions, such as pregnancy, may necessitate higher doses. Deficiency in Vitamin E can present as hair thinning and increased oxidative stress on scalp tissues, leading to premature hair follicle aging. Vitamin E's antioxidant properties are vital in combating the free radicals that can damage hair follicles, leading to brittle hair. People diagnosed with vitamin D deficiency must begin treatment as soon as possible to redress the health complications which may be caused by the condition. Treatment for vitamin D deficiency normally involves supplementing a person’s nutritional intake in order to ensure that they receive the quantity of vitamin D that they need for their cells to function healthily. To confirm a suspected diagnosis of vitamin D deficiency, one’s doctor will perform a blood test (called 25-hydroxy vitamin D test) , measuring the serum 25(OH)D levels in the blood.
It can take anywhere from 6 weeks to 6 months for your hair to regrow after restoring vitamin D levels to a healthy range. However, it's important to note that vitamin D alone may not be enough to reverse your hair loss. You should also consider other lifestyle changes and treatments in order to see the best results.
Sun Exposure
If a deficiency is allowed to become severe and prolonged, it can disrupt the hair growth cycles long-term. But catching and correcting it early on can help minimise permanent thinning and loss. It's also found naturally in animal-based foods like fatty fish, fish liver oils, egg yolks, fortified dairy products and beef liver. If you're experiencing potential symptoms, getting an accurate diagnosis of vitamin D deficiency is crucial. If you identify with any of these risk factors, please know you're not alone.
The Endocrine Society recommend that adults between the ages of 19 and 55 receive 600 IU of vitamin D daily. The unit “IU” stands for international unit, which describes how potent a vitamin or supplement is, rather than its mass. Vitamin D supplements should be taken with meals, particularly ones with plenty of healthful fats. People with an underlying medical condition will experience symptoms of the primary cause and symptoms of a vitamin D deficiency, as well.
Hair loss begins when there is no new hair replacing those hairs that have fallen out. Maintaining a healthy diet rich in vitamin D and getting a safe amount of sunlight will help ensure optimal levels, but some people may require the use of available vitamin D supplements. This research determines that maintaining sufficient vitamin D levels in the blood reduces the likelihood of experiencing the effects of telogen effluvium. The study found that individuals who qualified for a diagnosis of telogen effluvium also showed a statistically significant difference in low levels of vitamin D in the blood.
In addition, Forghani et al. identified novel nonsense mutations in the VDR gene in two patients that resulted in hereditary vitamin D-resistant rickets and alopecia [65]. A recent review article evaluating biotin and its effect on human hair found 18 reported cases of biotin use on hair and nail. In ten of these 18 cases there was a genetic cause of biotin deficiency; the remaining eight patients had alopecia that was improved after they had taken biotin supplementation. There were three cases of uncombable hair syndrome, three cases of brittle nail syndrome, one case of alopecia due to valproic acid intake, and one case of an infant on a biotin-free dietary supplement.
