The Role of Vitamins and Minerals in Hair Loss: A Review PMC

can vitamin d deficiency cause hair loss

You can determine vitamin D levels with a blood test called 25-hydroxyvitamin D. It's not a routine test, but a healthcare provider might recommend it if you're at high risk of vitamin D deficiency or have symptoms. Low vitamin D levels can cause muscle weakness, fatigue, hair loss, and other symptoms. Vitamin D affects most body systems and is important to overall health. With chronic and/or severe vitamin D deficiency, a decline in calcium and phosphorus absorption by your intestines leads to hypocalcemia (low calcium levels in your blood).

While most people in the USA ingest adequate amounts of folate, certain groups are at risk for deficiency (usually in association with poor diet, alcoholism, or a malabsorptive disorder). If you experience vitamin D deficiency in the form of hair loss, treating the scalp and hair follicles is an essential aspect to regain healthy hair growth. This can be achieved by using clinically tested products that have proven to be highly effective for various forms of hair loss. This includes, for example, Spectral.F7 Lotion, which can be easily integrated into daily life and can also help with vitamin D deficiency by stimulating hair growth. Contrary to the belief that only a vitamin deficiency can trigger hair loss, excessive intake of certain vitamins has also been identified as a potential cause for this condition.

For mild deficiencies, increasing the amount of time spent in the sun can also help. However, it is important to wear sunscreen and avoid prolonged exposure to reduce the risk of skin damage. When treating low vitamin D levels, a doctor will do a blood test every few months to see if a person’s levels are increasing. If a medication is causing a vitamin D deficiency or hair loss, a person should speak to their doctor about alternatives.

Recognising them early can be a crucial step in seeking the help and care you deserve. The sooner you identify a deficiency, the quicker you can act to correct it before further hair loss occurs. So, it’s important that you look out for potential symptoms and try to include vitamin D in your everyday life.

However, it’s best to speak with a healthcare professional if you’re experiencing frequent infections or illness without any known cause. They could discuss any supplements and appropriate vaccines for your overall health. The authors of a few studies suggest that the levels of folate or vitamin B12 might modify the progression of AA, but data are still too limited to recommend screening or supplementation of B vitamins.

It also helps to avoid follicle inflammation that results in hair loss. With iron deficiency anemia, your body doesn't have enough iron to make healthy red blood cells. Iron is needed to make hemoglobin, the protein in red blood cells that binds oxygen. Another way to increase vitamin D levels and treat hair loss is to use a hair growth-stimulating shampoo such as Neofollics Shampoo. This contains a unique combination of ingredients and vitamins and nutrients that are important for hair growth and can help regulate the hair growth cycle and promote hair growth. However, this requires longer-term, regular use to achieve optimal results.

With that in mind, she highly recommends consulting with an experienced dermatologist who will be able to assess your condition and offer all the best treatment options. If you’re not sure whether vitamin D deficiency is the culprit behind your hair loss, make sure that you consult your GP, who can help you get to the root of the problem. Hypothyroidism, which can cause you to feel cold, can be due to an iodine deficiency.

Treatment typically involves obtaining more vitamin D through sun exposure, foods or supplements. Experiencing hair loss can be distressing, and you might be wondering if vitamin D deficiency could be a contributing factor. Vitamin D is crucial for many aspects of human health, including the health and growth of your hair. If your body isn’t getting enough vitamin D, it might negatively affect your hair and cause you to see more strands falling out.

Symptoms of biotin deficiency

Vitamin B12 is essential for DNA synthesis, erythrocyte formation, and neurological function. Deficiency may result from inadequate dietary intake, malabsorption syndromes, or the use of certain medications. Clinical guidelines suggest that adults require approximately 2.4 micrograms of vitamin B12 daily. Supplementation may be necessary for individuals unable to meet their folate requirements through diet alone. Adults' recommended dietary allowance (RDA) is 400 micrograms of dietary folate equivalents (DFE) per day.

COVID-19 brought about death and illness, shuddered schools and businesses, and put people's lives on pause. The resulting emotional stress had significant repercussions, among them unprecedented hair loss for many people. This deficiency is one of the most common in the world with more than one billion people affected (11). However, some populations are at a greater risk of developing this deficiency than others.

Specifically, hypervitaminosis A, which occurs from an overconsumption of vitamin A, has been linked to hair loss. The mechanism behind this involves the retinol form of vitamin A, which, in high levels, can inhibit the hair follicle cycle, leading to a cessation of hair growth and subsequent hair loss. A retrospective cross-sectional study evaluated folate and vitamin B12 levels in 115 patients with TE (acute and chronic). The results showed that 2.6% of subjects had vitamin B12 deficiency but none had folate deficiency. The authors of a case–control study attempted to determine the prevalence of trichodynia in 91 patients with diffuse hair loss, including those with AGA and TE.

In any case, it’s always good to take action if your vitamin D level is low (more practical tips on this later). Though we can’t infer any cause/effect relationship between vitamin D and alopecia areata, the correlation is an interesting one. That said, before adding any supplements to your routine, Green says you should speak with a doctor first to ensure that you’re taking the right amount and targeting the proper cause. The Endocrine Society recommend that adults over 55 years old receive between 600 and 800 IU per day of vitamin D. Finally, they recommended between 400 and 600 IU per day of vitamin D for children. Research suggests that when a person lacks Vitamin D, the most effective treatment is for them to take vitamin D supplements.

There are two types of tests that they might order, but the most common is the 25-hydroxyvitamin D, known as 25(OH)D for short. Several different biological and environmental factors can also put you at a greater risk of developing vitamin D deficiency, such as older age and the amount of melanin (pigment) in your skin. More specifically, you need vitamin D so your body can use calcium and phosphorus to build bones and support healthy tissues. How much vitamin D you should take depends on your vitamin D levels, average sunlight exposure, health status, and skin tone.

The best sources of this fat-soluble vitamin are food, supplementation and sunlight. However, too much UV exposure may increase one’s risk of skin cancer, which is why dermatologists suggest always wearing sunscreen to protect the skin. The role of folate and vitamin B12 in nucleic acid production suggest that they might play a role in the highly proliferative hair follicle [43]. However, few studies to date have addressed the relationship between B vitamins and hair loss. Turkish authors investigated folate level in 43 patients with AA and 36 healthy controls and found no significant differences in serum folate and vitamin B12 levels between the AA subjects and the healthy controls [44]. Also, the authors found that serum levels did not vary with duration or activity of the disease [44].

Vitamin B12 is a cofactor for methionine synthase and thereby affects the synthesis of nearly 100 substrates including DNA, RNA, and proteins [22]. The recommended dietary allowance of vitamin B12 is 2.4 mcg for adult U.S. populations. There is no established upper limit for vitamin B12 intake, as it has a low potential for toxicity [22]. Some of the key symptoms signalling low vitamin D levels include hair loss or thinning, fatigue, bone/muscle weakness, frequent sickness, depression and impaired wound healing.
