Why is Vitamin C Important?Vitamin C is essential for a wide range of bodily functions, including wound healing, tissue support, bone health, collagen production and protection from free radical damage. Vitamin C is good for your hair as it is vital for the absorption of iron – a deficiency of which can cause chronic hair loss and hair not growing past a certain length. Your body can neither make nor store this vitamin on its own, therefore it is imperative to consume foods or supplements containing it on a daily basis. Vitamin C DeficiencyVitamin C deficiency can cause dry, brittle hair. It can also lead to iron deficiency anaemia (because iron can only be absorbed in the presence of Vitamin C), and this often results in hair shedding. Vitamin C deficiency can be caused by the following factors:
It is preferable to obtain Vitamin C through your diet, rather than supplements. However, when hair loss and/or hair thinning is an issue, a combination of supplements and a healthy diet is best for encouraging regrowth. Be aware that when you ingest iron, you also need to have sufficient Vitamin C levels, or your body will not be able to absorb the iron.

Foods Rich in Vitamin CBecause Vitamin C is water-soluble, it is easily lost from foods through storage, overcooking and boiling. This means it is super important to obtain it from fresh fruits and vegetables — the following are packed with Vitamin C:
If you want healthy, luscious locks, it’s important to maintain an overall nutritious diet. In fact, there’s very limited research to show that hair vitamins and supplements promote hair growth in generally healthy people. However, some nutrient deficiencies have been associated with hair loss. In these instances, a supplement may offer some benefit (2). Deficiencies in several nutrients — including some B vitamins, vitamin D, vitamin C, iron, and zinc — may contribute to hair loss. B vitaminsDeficiencies in riboflavin, biotin, folate, and vitamin B12 have been associated with hair loss (2 ). While biotin is one of the more popular supplements for hair, skin, and nails, the research supporting its benefits for people with adequate biotin intake is limited (2). Similarly, research is inconclusive on whether folate and vitamin B12 are effective for hair growth in people with adequate intakes (2, 3). Deficiencies in riboflavin, folate, and biotin are rare. However, some individuals may be at a higher risk, including those with restrictive diets (4 , 5, 6). Vitamin B12 deficiencies are more common, especially in older adults and people following a vegan diet (7). Vitamin CVitamin C is a powerful antioxidant that has several important roles that can affect hair health, including:
Still, keep in mind that vitamin C deficiency is rare and many people likely get enough of this vitamin from their diet. Vitamin DVitamin D deficiency is associated with hair loss, but research supporting vitamin D supplementation for hair growth is limited (2, 9, 10). Still, because most people likely don’t get enough vitamin D through diet alone, it’s worth asking a healthcare professional to see whether you could benefit from a vitamin D supplement (11). IronIron is an important mineral for many bodily functions, including carrying oxygen to tissues throughout your body (12). Iron deficiency, which is the most common nutrient deficiency in the world, can lead to anemia and hair loss, especially in women (2, 12, 13). ZincZinc, another important mineral, contributes to immune function, DNA synthesis, and wound healing (14 ). A zinc deficiency can lead to hair loss, though the research on the use of zinc supplements for hair growth is inconclusive (2, 14). We chose the best hair growth vitamins based on the following criteria:
Best clinically testedNutrafol Core for Women
Nutrafol offers subscription-based hair growth supplements designed to help support hair growth and prevent thinning. According to the company’s website, the capsules contribute to thicker hair, lashes, and brows and reduced shedding. One study in 40 women with self-reported hair thinning found daily intake of Nutrafol Core for Women to be effective in improving hair growth, as well as hair thickness and volume, over 6 months (15). Similarly, another study in 98 men and women with thinning hair found significant improvements in hair growth, density, volume, and shedding after daily intake of Nutrafol Core for Men or Women for 6 months (16). Keep in mind that there is a risk of bias, as researchers in both studies were employed by Nutraceutical Wellness LLC. Nutrafol capsules are non-GMO and free from gluten, soy, dairy, and artificial additives. However, because these capsules contain collagen sourced from wild cod, they are not vegan-friendly. Keep in mind that Nutrafol Core for Women is not recommended for people under age 18 or those who are pregnant or nursing, though Nutrafol also offers a supplement formulated for postpartum hair loss. Nutrafol products are produced in a CGMP-compliant facility and third-party tested for heavy metals, pesticides, and chemicals. Best gummyOLLY Heavenly Hair Gummies
If you aren’t a fan of swallowing tablets or capsules, a gummy vitamin could be a better option. OLLY Heavenly Hair Gummies contain biotin and zinc, as well as several herbs that may support hair growth. For example, the gummies include amla extract, or Emblica officinalis Gatertn, which comes from a flowering tree in Asia and is thought to have anti-inflammatory and antioxidant properties (17). While topical use has been shown to be effective for improving hair density and growth, oral use of amla hasn’t been found to have the same effect (18). These gummies also contain horsetail extract and silica, which may help prevent hair shedding and thinning, though research is mixed (19). Keep in mind that horsetail can interact with certain medications, so it’s important to consult a healthcare professional before trying this supplement (20). OLLY supplements are third-party tested to ensure purity and potency. Best women’s multivitamin for hairNature Made Multi for Her
While not specifically formulated for hair growth, a multivitamin may help fill nutrient gaps in your diet, which could potentially be associated with hair loss (2, 21). Nature Made Multi for Her contains nutrients that are important for healthy hair, including zinc, vitamin C, B vitamins, and vitamin D. It also contains 100% of the Daily Value (DV) for iron in the form of ferrous fumarate, a highly absorbable form of iron (2, 12, 22). This women’s multivitamin is third-party tested and verified by United States Pharmacopeia (USP), which means you can trust the quality of the product and accuracy of the label. Best for menNature Made Multi for Him
For men, Nature Made Multi for Him is one of the best options because it contains important nutrients for hair health, such as zinc, B vitamins, and vitamins C and D (2). However, it does not include iron, as men have much lower iron needs than women and are less likely to have a deficiency (12). As with the women’s formulation, some of the nutrients are included at doses that exceed 100% of the DV, which may be excessive for some individuals. Best with vitamin DPure Encapsulations Vitamin D3 Liquid
Vitamin D deficiency has been linked to hair loss, and in some instances a healthcare professional may recommend a supplement (2, 10). Pure Encapsulations Vitamin D3 Liquid is one of the best vitamin D supplement options because it’s third-party tested and free from major allergens and comes in a convenient liquid form. Each 5-drop serving contains 1,000 IU of vitamin D3 that’s derived from harvest lichen, meaning that it’s vegan-friendly. In addition to being certified gluten-free, this supplement is free from major allergens, GMOs, and artificial colors and flavors. Best B-ComplexPure Encapsulations B-Complex Plus
A vitamin B complex supplement may benefit hair growth in people who have a deficiency, although deficiencies in this vitamin are relatively rare (2). However, limited research suggests that folate and vitamin B12 supplements may support hair growth even in people who do not have a deficiency (2). Pure Encapsulations B-Complex Plus contains all eight B vitamins and is certified gluten-free and GMO-free. All the B vitamins are included at doses higher than 100% of their DVs. While toxicity with B vitamins is rare, it’s still possible, so it’s important to run any new supplement by a healthcare professional before trying it (23). Best zinc supplement for hair growthThorne Research Zinc Picolinate
While the research on the use of zinc supplements for hair growth is mixed, zinc deficiency has been associated with hair loss (2, 14). This supplement from Thorne Research is a great option as it contains a highly absorbable form of zinc and is free of additives and fillers. Thorne Research is a well-trusted supplement brand. All its supplements are manufactured in NSF-certified facilities and tested multiple times throughout manufacturing to ensure purity, potency, and quality. Thorne Research Zinc Picolinate is also NSF Certified for Sport, meaning it’s free of more than 273 substances banned by competitive sports organizations. Best prenatal vitamin for hair growthFullWell Prenatal Multivitamin
FullWell Prenatal Multivitamin provides a broad spectrum of vitamins and minerals that may support hair growth, including B vitamins, zinc, and vitamin D (1). Designed for people who are pregnant or nursing, this prenatal contains choline — a nutrient that other prenatal vitamins often lack — and methylfolate, which is a more absorbable form of folate. FullWell products are formulated by a registered dietitian and third-party tested. Certificates of analysis (COAs) are also available upon request. Best postnatal vitamin for hair growthRitual Postnatal Multivitamin
After giving birth, many women notice extra hair shedding, which can be alarming (24). Ritual’s postnatal vitamin contains a variety of vitamins and minerals to support recovery in the postpartum period. Specifically, it contains docosahexaenoic acid (DHA), an omega-3 fatty acid that may be effective in promoting hair growth, improving hair density, and reducing hair loss (25, 26). It also includes vitamin D, iron, and zinc, all of which have been linked to hair loss in people with deficiencies (2). Ritual’s postnatal vitamin is third-party tested for quality and accuracy. Best collagen supplement for hair growthThorne Research Collagen Plus
Collagen is a type of protein that contains amino acids that can be used to build keratin, the protein found in hair (8). Recently, collagen has become a popular supplement for healthy hair, skin, and nails. However, the research on its effectiveness for hair growth is limited (27). Still, if you want to try a collagen supplement, this product from Thorne is one of the best options. Thorne Research Collagen Plus is designed to support healthy hair, skin, and nails by providing a combination of collagen peptides, plant-based antioxidants, and nicotinamide riboside — a compound that may help promote healthy aging and cellular repair (28). This berry-flavored powder is sweetened with stevia and is gluten-, dairy-, and soy-free. Thorne Research supplements are tested four times throughout manufacturing and are produced in NSF-certified facilities. Here’s a quick look at how our top picks compare: When shopping for hair growth supplements, it’s important to consider the following factors:
Hair loss has many possible causes, including some that require medical intervention (29). It’s always a good idea to consult a healthcare professional. They can determine the cause of your hair loss and develop a personalized treatment plan. Do hair growth vitamins work?In most cases, individuals who see benefits from taking hair growth vitamins are those who have nutrient deficiencies, as insufficient intake of some nutrients — like iron, zinc, and vitamin D — has been linked to hair loss (2). However, specific research on the effectiveness of hair growth vitamins in generally healthy individuals is lacking (9). Does biotin work for hair growth?Biotin is a very popular B vitamin that people often use for hair, skin, and nail health. However, the research on its effectiveness is mixed. Because biotin supplements can affect the results of some blood work, it’s important to let a healthcare professional know if you’re taking biotin supplements (2, 3, 30). Are hair growth vitamins safe to take?Most vitamin and mineral supplements are considered safe for healthy adults. However, many people are able to meet their nutrient needs through diet alone, and taking supplements could cause you to overconsume some nutrients (31). It’s important to consult a healthcare professional before starting any new supplement, especially if you are pregnant, nursing, or taking medications. Choosing a product that has been third-party tested will also help ensure that the product you buy contains what is listed on the label. How can I thicken my hair?There are several home remedies that may help thicken hair, including supplements and FDA-approved hair loss products. It’s best to consult a healthcare professional to determine the best option for you. Many factors, including age, genetics, and hormones, can affect hair growth. Deficiencies in certain nutrients, such as vitamin D, iron, and zinc, can contribute to hair loss. While some people swear by hair growth supplements, research supporting the use of these products is lacking. Additionally, ingredients often found in hair supplements may be contraindicated for some individuals, especially those who are pregnant or nursing. If you’re concerned about your hair, it’s important to ask a healthcare professional before taking hair growth supplements. Does vitamin C increase hair growth?Vitamin C Benefits for Hair
