In addition, a recent study showed that some human chorionic gonadotropin (hCG) devices are subject to biotin interference in individuals taking dietary biotin supplements. Therefore, clinicians and laboratory technicians need to be aware of this potential interference with qualitative urine hCG tests and should suggest quantitative serum hCG measurement. A person’s first defense against hair loss caused by a vitamin D deficiency is spending 15 to 20 minutes outside per day and eating foods that are rich in vitamin D. 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. If you have a true biotin deficiency, larger doses of biotin supplementation ranging from 10,000 to 30,000 μg/day are recommended.
Biotin
Many substances can be classified as antioxidants, including zinc, selenium, and vitamins A and E, as described previously in this article, as well as vitamin C and polyphenols [71]. In vitro studies of dermal papilla cells from male AGA patients have shown that oxidative stress may have an important role in the balding phenotype and development of AGA [72]. One trial included L-cysteine, a constituent of keratin, in combination with medicinal yeast and pantothenic acid [65]. Other trials have evaluated supplements containing marine proteins in conjunction with multiple other nutrients [66–69]. However, it is difficult to evaluate the results of these trials, as the composition of these nutritional supplements is not disclosed. To elucidate the role of vitamin D in FPHL and TE, additional large-scale trials are necessary [77].

A variety of treatments have been developed to help regrow hair and thicken existing hair on patients with alopecia, dermatologists say. Their effectiveness largely depends upon what type of alopecia you have and how quickly you start treatment. Alopecia areata is an autoimmune disease that causes hair to fall out in nickel- or quarter-size patches. It’s essential that you not become pregnant while taking spironolactone. To prevent pregnancy, your dermatologist will also prescribe a birth control pill if it’s possible for you to get pregnant.
Fatty Acids
Answering these queries is frequently challenging, given the enormous and conflicting body of evidence that exists on this subject. A number of symptoms, such as hair loss, can occur when your body lacks the recommended amount of vitamin D. Vitamin D deficiency has been linked to alopecia, also known as spot baldness, and a number of other health conditions. These include bone softening, low bone density, osteoarthritis, heart disease, and cancer. There are many causes for thinning hair, including genetics, medical conditions, medications, hormonal changes, and nutritional deficiencies.
Your dermatologist can tell you whether your hair may start to grow again on its own. For example, a woman may have had a baby a few months ago, and this may be causing obvious hair shedding. Use these professionally produced online infographics, posters, and videos to help others find and prevent skin cancer. In addition to adding these foods to your diet, be sure to get plenty of sunlight. Nearly 90% of vitamin D is synthesized under the influence of the ultraviolet rays of the sun. Essential fatty acids, like omega-3, are responsible for regulating a variety of natural functions.

If you are on a vegetarian diet, you can substitute non-vegan products with other foods high in iron such as lentils, cashew nuts, dried apricots, and figs. Despite the fast-spreading myth, the overdose of vitamin D has nothing to do with hair loss. Still, it can cause toxicity – the condition that can lead to weakness, nausea, vomiting, and other unpleasant symptoms, so you should better avoid it anyway.

Hair loss can be caused by multiple factors, including genetics, hormonal changes, medical conditions, and even poor nutrition. It’s essential to recognize that vitamin deficiencies can play a significant role in exacerbating hair loss. In 2006, an investigative study described gene expression specific to the bulge region of the hair follicle [116]. St. Pierre et al. [93] reviewed the literature for the function of genes that may be affected by fluctuating iron levels.

While the process of thinning hair can be concerning at first, many types of thinning hair are treatable. 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.
Exploring Specific Vitamin Deficiencies and Hair Loss
Genetics play the single most important factor in dictating the severity and timeliness of when you might experience hair loss. While there isn’t a single cure for these inherited traits, there are some treatments for hair loss that have proven effective in slowing, stopping and even reversing hair loss. A deficiency can influence hair loss, especially in vegetarian or low-meat diets. Vegetarians or vegans who don’t consume enough animal products can often be deficient in B12. While it’s necessary for hair growth, an excessive amount can have the opposite effect. Healthcare professionals found that her blood levels of selenium were nearly five times higher than the normal range.
Several studies also note that symptoms often appear during pregnancy, a time during which women’s iron levels tend to drop (49, 50). For example, they may order tests to determine if you have any vitamin or mineral deficiencies. If so, they may recommend adding or increasing the dietary amount of certain foods or starting supplementation. The most common cause of alopecia is an inherited condition called male- or female-pattern hair loss. Start by seeing a board-certified dermatologist, recommends Dr. Garcia. They can run a blood test to what nutrients you might be missing out on while assessing other factors that might also be contributing to your hair loss.
You’ll have more success — while avoiding potential health risks — if you first find out if you’re deficient in a nutrient and if supplementation can benefit your hair and health. Selenium is one of the top nutrients you will find in hair and skin supplements, alongside biotin. But there’s little to no evidence that selenium helps with hair growth, and overdoing it with this nutrient can lead to hair loss, brittle nails, skin rashes, nausea, and more. Alopecia areata is an autoimmune condition that is characterized by “round patches of hair loss on the scalp,” although it can occur elsewhere on the body, Agbai says. While the exact reason for this type of hair loss is unknown, it is generally understood that “the immune system mistakenly attacks hair follicles, leading to hair loss,” she adds.
But too much iron also isn’t good — it can lead to a condition called haemochromatosis, and one of the first signs of this is hair loss. According to Healthline, other common types of alopecia include traction alopecia, telogen effluvium, alopecia areata, central centrifugal cicatricial alopecia (CCCA), and lichen planopilaris (LPP). If you’ve noticed an excessive amount of hair shedding, a receding hairline, or that the hair on the crown of your head becoming increasingly sparse, you’re probably experiencing a form of hair loss. Losing your hair can be a distressing experience, but you’re not alone.
But you can also eat food products fortified with vitamin D, such as certain cereals, milk, and orange juice. Vegan and vegetarian diets, though, tend to lack enough vitamin D, so supplements may be needed if you follow that lifestyle. Ensuring an adequate amount of sleep each night is also vital for maintaining overall health, including healthy hair. Lack of sleep can disrupt normal bodily functions, potentially leading to conditions that may contribute to hair loss. Additionally, managing stress levels is crucial as high-stress levels can contribute to hair thinning and loss.
Over-supplementation of some nutrients may result in multiple toxicities, while over-supplementation of certain nutrients, including vitamin A, vitamin E, and selenium, may actually result in hair loss. In terms of other amino acids and proteins, no clear conclusions may be drawn about the role of supplementation in hair loss. One study examined the role of L-lysine, an essential amino acid that may play a role in iron and zinc uptake.
This fat-soluble vitamin is stored in the liver and plays an important role for your immune system, vision, and reproduction. But overdoing it can negatively impact your hair and hair growth patterns. Vitamin a is a nutrient that is abundant in a number of foods and should be fairly easy to obtain from food sources alone. Baldness is often hereditary, and is activated by a shift in your hormones.
Shampoos for thinning hair or hair loss also contain vitamins and amino acids to promote a healthier scalp. Studies on the role of iron in AA have shown a discrepancy in the results between females and males. There is a need for placebo-controlled clinical trials evaluating iron supplementation in the treatment of AA. Most studies on zinc have revealed lower serum levels in AA patients than in controls. Vitamin D modulates growth and differentiation of keratinocytes through binding to the nuclear vitamin D receptor (VDR). Murine hair follicle keratinocytes are immunoreactive for VDR, showing their highest activity in the anagen stage [61].
