This is evident in a few areas — and vitamins and minerals are one. Taking too many supplements doesn’t automatically guarantee your health will be better or that you’ll get more radiant skin or longer hair. In fact, if you don’t have a deficiency in any one vitamin, there’s a good chance taking a lot of it will either not have an effect at all or worse — it can backfire and cause health complications. A large body of research has shown that these over-the-counter creams and foams, applied to the scalp daily, are effective at stimulating hair growth, increasing hair density and halting hair loss over time. Of course, not every vitamin that advertises hair-boosting benefits delivers on the promise of healthy hair growth.
An Overview of Vitamin Deficiencies That Cause Hair Loss
“When the body does not have enough vitamin D, the keratinocytes in hair follicles have trouble facilitating hair growth, resulting in shedding and hair loss,” she explains. Yes, nutritional deficiencies, especially those related to vitamins and minerals, can lead to Nutritional Deficiency hair loss. So, if you’re experiencing thinning hair, you might ask yourself which vitamin deficiency causes hair loss. Interestingly, hair loss isn’t typically caused by vitamin deficiency, although having too much of certain vitamins can contribute to thinning hair. Hair loss can also be caused by a lack of protein or iron in your diet. Biotin deficiency causes hair loss, but there are no evidence-based data that supplementing biotin promotes hair growth.

Unsaturated fatty acids may modulate androgen action by inhibition of 5α-reductase, similar to the drug finasteride [42]. Additionally, arachidonic acid, an omega-6 fatty acid, may promote hair growth by enhancing follicle proliferation [43]. It reduces harm done by free radicals and protects the body cells including hair and scalp cells from their negative influence. Vitamin E prevents hair loss, improves scalp circulation, and creates a protective barrier on the scalp. If you eat a balanced diet, it’s unlikely that you’re low in biotin.

Treatments for Alopecia and Hair Loss
Today, people are a lot more concerned about their appearance than ever. For this, they are constantly engaged in multiple physical activities. This condition is quite common, and we often receive questions about it, prompting us to delve into a detailed exploration to enhance understanding.

Vegan and vegetarian diets, though, tend to lack enough vitamin D, so supplements may be needed if you follow that lifestyle. In some cases, adjusting your diet to include nutrient-rich foods may help improve hair health. However, supplements and medical guidance may be necessary for severe deficiencies. But if you don’t have a confirmed biotin deficiency, taking biotin supplements won’t help with hair loss. That’s surprising to many people since many companies sell shampoos and other products with biotin, claiming that they’ll improve hair health. The recommended dietary allowance for selenium is 55 μg daily for individuals aged ≥ 14 years in U.S. populations.
Which vitamins and minerals are best for hair loss?
It’s important to talk with a healthcare professional before you begin using essential oils and be sure to research the quality of a brand’s products. Early treatment of a receding hairline (frontal fibrosing alopecia) might help avoid significant permanent baldness. The cause of this condition is unknown, but it primarily affects older women. In the type of patchy hair loss known as alopecia areata, hair loss occurs suddenly and usually starts with one or more circular bald patches that may overlap. That said, if your vitamin D levels are deficient, Paviol says that there are other, more intensive ways to supplement the vitamin.
How much vitamin K is safe per day?
In terms of other amino acids and proteins, no clear conclusions may be drawn about the role of supplementation in hair loss. Vitamin A is a group of compounds including retinol, retinal, retinoic acid, and provitamin A carotenoids. Selenium is an essential trace element that plays a role in protection from oxidative damage as well as hair follicle morphogenesis. Rats deficient in selenium display sparse hair growth [46], while knockout mice lacking specific selenoproteins exhibit progressive hair loss after birth [47]. In addition, multiple genes have been identified in the human hair follicle [15], and some may be regulated by iron [16]. In a mouse model, reversal of ID led to restoration of hair growth [17].
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. A healthcare provider can diagnose nutritional deficiency-related hair loss through blood tests that assess your nutrient levels. They can identify any deficiencies that may contribute to your hair loss.
Published data on AA suggest that vitamin D, due to its immunomodulatory effect, may be involved in AA [66, 67]. Lee et al. conducted a systematic review and meta-analysis of observational studies on the prevalence of vitamin D deficiency and/or serum vitamin D levels and AA [68]. These authors analyzed a total of 14 studies that involved 1255 patients with AA and 784 control patients without AA. 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.
Here are some ways to combat hair loss caused by nutritional deficiencies. We performed a broad literature search of PubMed and Google Scholar in July 2018 to compile published articles that study the relationship between vitamins and minerals, and hair loss. After three authors had independently screened titles and abstracts for relevance and had thoroughly examined the clinical results, 125 articles were selected to be included in this review.
One report described a single patient with alopecia, without clear deficiency, who experienced improvement following oral zinc therapy [40]. Screening in those with risk factors is indicated, as hair loss due to zinc deficiency can be reversed. A case series demonstrated reversal of hair loss following oral supplementation in five patients with TE and zinc deficiency [37]. Other groups at risk include patients with malignancy, those with liver or renal dysfunction, pregnant women [31], and patients with alcoholism [32].
Doctors often prescribe oral medications to be used along with topical minoxidil because studies show the combination boosts hair production. Low-dose oral minoxidil (prescribed off-label) has been found to be effective and safe for most patients, Mirmirani says. Other oft-used drugs include finasteride (Propecia) and spironolactone. If you have scarring alopecia or alopecia areata, your doctor may recommend an anti-inflammatory medication such as the JAK inhibitor Olumiant (baricitinib) to help tamp down your immune system.
While the link between a low nutrient diet and these skin conditions is not fully understood, people with dandruff or seborrheic dermatitis might consider consuming more of these nutrients. To confirm whether you have a deficiency, you can talk with a healthcare professional who can order tests to check your vitamin levels. Vitamin D deficiency has been linked to alopecia, the autoimmune condition that causes bald patches on the scalp and other areas of the body. Another study found that women 18 to 45 years old who experienced alopecia or other types of hair loss had low levels of vitamin D. A number of symptoms, such as hair loss, can occur when your body lacks the recommended amount of vitamin D.
While the process of thinning hair can be concerning at first, many types of thinning hair are treatable. If your hair is thinning due to other reasons, you may be able to try topical products, such as shampoos and even prescription medications. Consider gentle hair products when available, and comb and brush hair only when needed. You can also place less stress on your hair by limiting the use of heated styling tools as well as tight hairstyles. To help manage stress, it’s important to take some time for yourself, whether it’s a meditation session or a relaxing hobby you enjoy. You may also consider talking with a therapist if you’re having a difficult time with chronic stress.
These tests can be uncomfortable, so they are done with an anesthetic medication. Your healthcare provider can identify problems such as Crohn's disease and some types of malabsorptive syndromes with these interventional examinations. If there is a concern that you could have a digestive problem causing vitamin malabsorption, your healthcare provider may order a test to examine the internal appearance of your stomach or intestines. A number of medical problems make it hard to properly absorb and metabolize vitamins. Talk to your healthcare provider about the best ways to protect your bone health. Vitamin E (a non-essential nutrient) might have a negative impact on wound healing.
Because of this link, getting adequate amounts of vitamin D can support hair growth and regrowth. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. Most people get the bulk of their vitamin D from basking in the sun. Not spending enough time in the sun or using too much sunblock limits your exposure, which can lead to a deficit of vitamin D.
