While your hair may regrow on its own, your dermatologist may recommend treatment to help it grow more quickly. In combination with a nutritious diet, these actions may help keep your hair healthy and reduce your risk of hair loss. If you don’t have a vitamin deficiency, taking high dosages of certain nutrients, such as vitamin A, vitamin E, and selenium, may trigger hair loss. Research has shown that taking vitamin D supplements promoted hair regrowth in some people with hair loss related to vitamin D deficiency (13). In vitro studies have shown that while polyphenols have antioxidant properties at low concentrations, they can potentiate ROS generation at higher concentrations [71, 74–75]. Compounds within plant foods, such as from fruits, vegetables, and grains, may be safer and healthier compared to isolated, high doses present in supplements [71].

Researchers are still studying how iron deficiency causes hair loss, but it appears to disrupt hair growth by diverting iron stores in the hair follicle to other areas of the body (6). Physicians must counsel their patients on the lack of research supporting these products. Since supplements are not regulated by the FDA, it is up to the physician and the consumer to review the efficacy and safety of supplements. Equally important is a discussion of the potential toxicity of some of these supplements.

The aforementioned medications interfere with biotinidase activity [34]. Evidence suggests that 50% of pregnant women are deficient in biotin [36]. Food and Drug Administration, biotin interference (from supplemental biotin) caused a falsely low result in a troponin test that led to a missed diagnosis of a heart attack and a patient’s death [28].
Recommended doses of vitamin D
As a general rule, consuming too much or over-supplementing vitamin A can cause hair loss [15, 16]. Typically, fat-soluble vitamin A is stored in the liver where its dispersal is tightly regulated by anabolic and catabolic reactions between the inactive and active metabolite. When levels of vitamin A are too high, the capacity of the transport system is exceeded and vitamin A spills over into the circulation [17]. Maintaining homeostasis—and by extension the proper concentration of active metabolite—is important for healthy hair [18]. Vitamin D affects many aspects of a person’s health and well-being, including hair growth.

People who have immune system deficiencies could also have thinning hair. Any number of lifestyle factors, genetics, recent life events (such as extreme weight loss in a short period of time or giving birth), or medical conditions can cause your hair to thin. Omega-3 helps your body fight inflammation, an underlying cause of numerous conditions. Lavender oil has been used with success by some people with pattern baldness. It’s also backed by animal research from 2016, though human studies are needed to confirm its effects. Lavender is often combined with other oils, such as those made from rosemary and thyme.

A deficiency can lead to hair loss, which is often reversible once the deficiency is addressed. Not eating enough calories and protein, such as in very low calorie diets, may lead to hair loss. Calorie restriction affects the energy supply to the hair follicle, which can lead to hair loss.

Summary The vitamins and minerals mentioned above are needed for hair growth, so diets rich in them may help prevent hair loss. However, the use of supplements — except in cases of deficiency — may cause more harm than good. 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.

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. It’s recommended that you get at least 600 IU (international units) — or 15 micrograms (mcg) — of vitamin D a day starting at the age of 1. For people over the age of 70, the suggested intake jumps to 800 IU (or 20 mcg). If you’re concerned about your vitamin D intake, ask your doctor about checking your vitamin D levels.
While vitamin D deficiency is linked to hair loss, it’s not likely the cause of loss for most people who deal with hair loss, according to Dr. Green. “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. In fact, only case reports have been used to justify the use of biotin supplements for hair growth.
However, when it comes to hair health, too much of a good thing can be harmful. An overload of Vitamin A may actually contribute to hair loss by speeding up your hair growth cycle in an unnatural way. Moving on from Vitamin D, let’s delve into the role of Vitamin A and its effects on your hair.
For adults aged ≥ 19 years, the tolerable upper intake level of preformed vitamin A is 10,000 IU [13]. 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. The role of nutrition and diet in treating hair loss represents a dynamic and growing area of inquiry. In this review we summarize the role of vitamins and minerals, such as vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, iron, selenium, and zinc, in non-scarring alopecia. 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.
Your cells require vitamin A in order to properly grow, and vitamin A will also help your immune system, vision, skin, teeth, kidneys, lungs, bones, and reproductive system. Hair loss can be the result of too much vitamin A (or not enough) so be careful that you find the right balance. Making a few changes to your diet, or taking the right supplements, can help to reverse hair loss. Smoking, drinking, stress, and lack of sleep may increase your risk of hair loss. However, people tend to experience this in extreme situations, such as after bariatric surgery, or after following an extreme diet that didn’t provide adequate calories or nutrients (26).
It can also occur among people living in a location where the soil lacks selenium [34]. Several clinical studies have implicated oxidant/antioxidant discrepancy in patients with AA, which is a disease dependent on autoimmunity, genetic predisposition, and emotional and environmental stress. These studies have been reviewed, with most reviewers reporting increased levels of oxidative stress biomarkers and decreased levels of protective antioxidant enzymes in patients with AA [79]. The presence of biotin can in fact interfere with tests that use biotin–streptavidin technology. Exogenous biotin in the sample competes with biotinylated reagents for the binding sites on streptavidin reagents, creating false positive or false negative results [29]. Other non-hormonal tests include cardiac and tumor markers, infectious disease serologies, biomarkers of anemia and autoimmune diseases, and concentrations of immunosuppressive drugs [29–32].
If you’re not getting enough of a certain vitamin or mineral, you and your doctor can also decide the best way to correct the problem. Minor shortages can often be fixed just by eating more of certain foods. “When dealing with hair loss, it is important to eat a well-balanced diet,” Dr. Garshick adds.
