Best Supplements, Minerals & Vitamins for Hair Growth

The appearance of hair plays an important role in people’s physical appearance and self-perception, so it can be devastating to experience hair loss, especially when there doesn’t seem to be anything you can do about it. But did you know that there are supplements and vitamins for hair growth?

In fact, poor nutrition and vitamin deficiencies are major factors when it comes to hair loss.

These supplements and vitamins for hair growth are natural hair loss remedies that work to fix the root of the problem, like regulating your hormone levels or fighting oxidative stress that increases with age.

Fewer than 45 percent of women go through life with a full head of hair while a majority of men go through some type of hair loss in their lifetimes.

The hair care industry knows that consumers have a great desire to look youthful now more than ever so it constantly delivers new products that promise to promote hair growth.

Before you spend your money on yet another product that may leave you disappointed, try using these supplements and vitamins for hair growth first.

Supplements and vitamins for hair growth

The truth is that hair loss is a complex process that involves various genetic, hormonal and environmental mechanisms.

Just like our skin, the hair follicle is subject to intrinsic and extrinsic aging. Intrinsic factors include our genetic and epigenetic mechanisms, and extrinsic factors include smoking and UV radiation.

Sometimes hair loss is due to a vitamin deficiency, too. Luckily, a deficiency can be corrected by adding vitamin-rich foods to your diet or using supplementation.

Some vitamins have antioxidant properties that help fight the extrinsic factors of hair loss, and some vitamins help the body balance hormone levels, another factor that stops hair growth.

If you’re wondering how to thicken hair naturally, the following supplements and vitamins for hair growth can help.

1. Fish oil

Oils rich in different fatty acid species have been used extensively in both animal and human studies to evaluate the effects on skin and hair health. Omega-3 fats nourish the hair, support hair thickening and reduce inflammation that can lead to hair loss, which is why fish oil benefits hair and is one of the top supplements for hair growth.

A 2015 study published in the Journal of Cosmetic Dermatology evaluated the effects of a six-month supplementation with omega-3, omega-6 and antioxidants on hair loss. In the randomized, comparative study, 120 healthy female subjects with female pattern hair loss participated.

The primary endpoint was the change in hair density evaluated on standardized photographs, and the secondary endpoint included changes in active hair follicle percentage and diameter distribution of hair growth.

After six months of treatment, photograph assessment demonstrated a superior improvement in the supplemented group. Hair growth increased compared to the control group, and 89.9 percent of the participants reported a reduction in hair loss, as well as an improvement in hair diameter (86 percent) and hair density (87 percent).

Eat omega-3 foods like salmon, mackerel, tuna, white fish, sardines, egg yolks, walnuts, hemp seeds and natto to reduce inflammation and balance hormones. If you don’t eat enough omega-3 foods, take one to two capsules or one tablespoon of a top-notch fish oil supplement to help reduce inflammation that causes hair disorders.

If you already take blood-thinning medications, including aspirin, speak to your healthcare provider before using fish oil because it may increase bleeding.

2. Zinc

Oral zinc compounds have been used for decades for treating disorders such as telogen effluvium and alopecia areata, forms of hair loss, because zinc benefits hair follicle health. Zinc is an essential co-factor for multiple enzymes and is involved with important functional activities in the hair follicle.

Zinc is also a potent inhibitor of hair follicle regression, and it accelerates hair follicle recovery. Studies have suggested that some alopecia areata patients have zinc deficiency, and oral zinc sulfate therapy serves as an effective treatment.

In a 2013 study, researchers evaluated the role of zinc status in each of the four types of hair loss, including alopecia areata, male pattern hair loss, female pattern hair loss and telogen effluvium. In all of the hair loss patients, the mean serum zinc was significantly lower than the control group.

The analysis of each group showed that all groups of hair loss had statistically lower zinc concentration, especially the alopecia areata group. The data led to the hypothesis of zinc metabolism disturbances playing a key role in hair loss.

A 2009 study published in Annals of Dermatology evaluated the therapeutic effects of oral zinc supplementation for 12 weeks in 15 alopecia areata patients who had low serum zinc levels. Oral zinc gluconate (50 milligrams) supplementation was given to alopecia areata patients without any other treatment.

The serum zinc levels were measured before and after zinc supplementation, and then a four-point scale of hair regrowth was used to evaluate the therapeutic effect.

After the therapy, the serum zinc levels increased significantly, and positive therapeutic effects were observed for nine out of 15 patients (66.7 percent). The researchers concluded that zinc supplementation needs to be given to the alopecia areata patients who have low serum zinc levels, and it could even become an adjuvant therapy for patients who didn’t experience results when using traditional therapeutic methods, which is why zinc is one of the most important minerals for hair growth.

3. B-complex vitamin (biotin and B5)

Biotin and pantothenic acid (vitamin B5) have been used as alternative treatments for hair loss, and they’ve proved to be important vitamins for hair growth. Biotin benefits hair by rebuilding hair shingles that have been damaged from over-shampooing, exposure to the sun, blow-drying and ironing.

Vitamin B5 supports the adrenal glands, which helps stimulate hair growth.

A 2011 study published in the British Journal of Dermatology examined the ability of a leave-on combination including panthenol, the alcohol analog of pantothenic acid, to affect the diameter and behavior of individual terminal scalp hair fibers. The treatment significantly increased the diameter of individual, existing terminal scalp fibers.

It also thickened hair fibers and increased the pliability, giving the hairs better ability to withstand force without breaking.

A major sign of a biotin deficiency is hair loss. A deficiency can be caused by smoking, impaired liver function or even pregnancy.

Research has suggested that a substantial number of women develop a biotin deficiency during normal pregnancy because the rapidly dividing cells of the developing fetus require biotin for synthesis of essential carboxylases and histone biotinylation. Researchers have concluded that significant alternations in markers of biotin metabolism during pregnancy and breastfeeding suggest that biotin intakes exceed current recommendations in order to meet the demands of these reproductive states.

To reverse hair loss and increase hair strength, take one B-complex vitamin tablet daily or take biotin and vitamin B5 separately. Eating biotin and vitamin B5 foods, such as eggs, beef, chicken, avocado, legumes, nuts and potatoes, also helps you avoid a deficiency and aids hair growth.

4. Vitamin C

Experimental evidence has suggested that oxidative stress plays a major role in the aging process. Reactive oxygen species or free radicals are highly reactive molecules that can directly damage cellular structural membranes, lipids, proteins and DNA.

With age, the production of free radicals increases and the amount of antioxidative enzymes that defend the body decrease, leading to the damage of cellular structures and the aging of hair. By working as an antioxidant, vitamin C fights oxidative stress that contributes to hair graying and hair loss.

To fight free radical damage and protect the hair from aging, fill up on vitamin C foods like oranges, red peppers, kale, Brussels sprouts, broccoli, strawberries, grapefruit and kiwi. If you need supplementation, take 500-1,000 milligrams of vitamin C twice daily as an antioxidant.

5. Iron

Several studies have examined the relationship between iron deficiency and hair loss, and some have suggested that iron deficiency may be related to alopecia areata, androgenetic alopecia, telogen effluvium and diffuse hair loss.

Researchers at Tehran University of Medical Sciences in Iran studied the relationship between iron body status and different types of hair loss. They conducted an analytical case-control study to assess whether diffuse telogen hair loss in women between the ages of 15 and 45 is associated with iron deficiency. Thirty women with documented telogen hair loss were compared with 30 women without hair loss.

The researchers found that of the nine patients with iron deficiency anemia, eight had telogen hair loss. The mean ferritin (a protein in the body that binds to iron) level was statistically significantly lower in patients with diffuse telogen hair loss than in subjects without hair loss.

The study suggested that women with an iron deficiency are at a higher risk of hair loss, and serum ferritin levels below or equal to 30 milligrams/milliliter are strongly associated with telogen hair loss.

To boost hair growth, add iron-rich foods into your diet every day. Eat plenty of spinach, Swiss chard, collard greens, egg yolks, beef steak, navy beans and black beans.

Because an iron deficiency may lead to hair loss, ensure that you get your daily recommended amount, and consider taking a daily multivitamin.

However, be wary of excessive iron supplementation. It can cause iron overload and should be avoided.

Patients who don’t respond to iron replacement therapy should undergo additional testing to identify other underlying causes of iron deficiency and hair loss.

6. Vitamin D

Hair follicles are highly sensitive to hormones, and vitamin D is a hormone that plays an important role in calcium homeostasis, immune regulation and cell growth differentiation. In the scientific world, it’s well-known that alopecia areata is commonly found in patients with vitamin D deficiency, vitamin D-resistant rickets or vitamin D receptor mutation.

Research has suggested that insufficient levels of vitamin D have been implicated in a variety of autoimmune diseases, including alopecia areata.

A cross-sectional study involving 86 patients with alopecia areata, 44 patients with vitiligo and 58 healthy controls was conducted. Serum 25-hydroxyvitamin vitamin D levels in patients with alopecia areata were significantly lower than those of the patients with vitiligo and the healthy controls.

Furthermore, a significant inverse correlation was found between disease severity and serum 25(OH)D levels in patients with alopecia.

Researchers concluded that screening patients with alopecia areata for vitamin D deficiencies seems to be of value for the possibility of supplementing these patients with vitamin D.

Direct sun exposure is the best way to absorb vitamin D. Plus, you can detox your body with the sun.

Sit in the sun for roughly 10-15 minutes to absorb about 10,000 units of natural vitamin D.

Topical application of vitamin D might also play a role in the restoration of hair cycle dysfunction in patients with alopecia areata. To increase your vitamin D levels with food sources, eat vitamin D-rich foods like halibut, mackerel, eel, salmon, whitefish, swordfish, maitake mushrooms and portobella mushrooms.

7. Saw palmetto

Saw palmetto is a plant extract known for its role in blocking dihydrotestosterone (DHT), a hormone associated with hair loss, particularly in men.

Research has revealed that saw palmetto may help reduce hair thinning and promote hair growth by inhibiting DHT production. It is often used in natural remedies for androgenic alopecia (male and female pattern baldness).

A 16-week randomized, placebo-controlled study published in 2023 had 80 healthy subjects (male and female) aged 18-50 randomly allocated to receive either a saw palmetto capsule, topical formulation or a placebo. Both the oral and topical formulations lowered hair fall by up to 29 percent and 22.19 percent, respectively, and hair density actually increased by 5.17 percent and 7.61 percent in the oral and topical treatment groups, respectively.

DHT was markedly reduced in the oral saw palmetto group.

8. Ashwagandha

Ashwagandha is an adaptogenic herb that helps the body cope with stress, one of the leading causes of hair loss. By balancing cortisol levels, ashwagandha may prevent stress-related hair thinning.

Additionally, it supports overall scalp health by improving blood circulation and reducing inflammation, promoting a healthier environment for hair growth.

In fact, a 2023 prospective, double-blind, randomized, parallel, placebo-controlled study published in the Journal of Ayurveda and Integrative Medicine found that an ashwagandha extract “improved hair growth and hair health indicators,” particularly enhancing hair density, growth and thickness compared to a placebo in healthy adults aged 18 to 45.

9. Tocotrienol

Tocotrienols are a form of vitamin E with potent antioxidant properties. Studies have shown that tocotrienols can help reduce oxidative stress in the scalp, which can contribute to hair loss.

By protecting the hair follicles from free radical damage, tocotrienols may support stronger, healthier hair growth.

One study even found that tocotrienol supplementation led to a 34.5 percent increase in the number of hairs compared to a control group after eight months, which actually saw a 0.1 percent decrease in number of hairs.

You can also eat vitamin E foods, such as nuts, seeds and leafy greens.

10. Curcumin

Curcumin, the active compound in turmeric, is known for its anti-inflammatory and antioxidant effects. It helps combat oxidative stress and inflammation, which can damage hair follicles and inhibit growth.

Curcumin has also been linked to improved circulation, providing the scalp with more nutrients that support healthy hair growth.

Researchers even experimented with a “curcumin-zinc framework encapsulated microneedle patch” to see if it could promote hair growth. They found that this microneedling approach, which included two of the top supplements and vitamins for hair growth, led to the following:

“In vitro, ZnMOF significantly improved the viability of DPCs against the excess reactive oxygen species (ROS) and inhibited the apoptosis induced by zinc deficiency. In addition, it also reversed the inhibitory effects of dihydrotestosterone (DHT) infiltration. Moreover, the ZnMOF-MN treatment has been proved to accelerate wound healing and increase hair follicles in wound healing models, and improved the hair regrowth in AGA animal models.”

Ultimately, the researchers concluded that this “treatment is a comprehensive solution with excellent therapeutic efficacy and patient-friendly features for promoting hair growth under various clinical conditions.”

11. Collagen

Collagen is an essential protein that helps maintain the structure and strength of hair. As we age, collagen production decreases, which can lead to brittle, thinning hair.

Supplementing with collagen can support hair growth by providing the necessary amino acids for building hair proteins and strengthening hair follicles.

You can eat collagen-rich foods and other collagen-promoting foods as well, such as eggs, meats and fish. These foods also contain other minerals and vitamins for hair growth.

12. Vitamin A

Vitamin A is essential for cell growth, including hair cells. It helps the scalp produce sebum, an oily substance that keeps the scalp hydrated and promotes healthy hair.

Some of the top vitamin A foods to eat include beef liver, sweet potatoes, carrots and fish.

However, it’s important to maintain the right balance, as too much vitamin A can actually lead to hair loss.

13. Protein

Hair is primarily made of a protein called keratin. Ensuring you have adequate protein intake is crucial for hair strength and growth.

A deficiency in protein can lead to brittle, weak hair that is more prone to breakage. Eating a protein-rich diet or supplementing with protein can help ensure hair has the building blocks it needs for growth.

14. Iodine

Iodine plays a critical role in thyroid function, and an underactive thyroid can lead to hair thinning and hair loss. Ensuring adequate iodine intake supports thyroid health, which in turn helps maintain healthy hair growth.

A deficiency in iodine can lead to hair becoming dry, brittle and more prone to shedding.

Add iodine-rich foods to your diet, like kelp, seaweed, cod, eggs and others. As an added bonus, many of these foods contain several minerals and vitamins for hair growth.

15. Folic acid

Folic acid, a B vitamin, is vital for cell division and the production of red blood cells. It helps deliver oxygen and nutrients to the scalp and hair follicles, promoting healthy hair growth.

Folic acid deficiencies can result in hair thinning and even hair loss, so ensuring you get enough of this vitamin is crucial for maintaining strong, healthy hair. Some of the best folic acid foods include lentils, broccoli, wheat germ, beets, beef liver, avocado and more.

16. Vitamin B2 (riboflavin)

Riboflavin is essential for cellular energy production and plays a role in metabolizing other nutrients necessary for hair growth, such as iron and B6. Deficiency in riboflavin has been linked to hair loss and skin disorders.

One comprehensive review of vitamins and minerals in human hair health stated that “only riboflavin, biotin, folate, and vitamin B₁₂ deficiencies have been associated with hair loss,” explaining that B2 deficiency disrupts cellular metabolism in hair follicles, impairing growth and causing shedding.

Clinically, repletion of riboflavin in deficient individuals reverses these effects, restoring normal follicular function and subsequent hair regrowth. Thus, maintaining adequate riboflavin levels is essential to support the metabolic demands of hair follicles and mitigate deficiency-related alopecia in humans.

17. Vitamin B3 (niacin)

Niacin improves blood circulation, including to the scalp, which can nourish hair follicles. It also helps maintain the structure of the hair shaft and supports healthy skin and hair growth.

A double-blind, placebo-controlled pilot study published in 2005 investigated the effect of topical niacin derivatives on women suffering from female pattern hair loss. Sixty participants applied either a niacin derivative formulation or a placebo for six months, with hair fullness assessed via standardized 35-mm photographic analysis.

At the end of the trial, the niacin-treated group demonstrated a statistically significant improvement in hair fullness compared to placebo.

Some of the top niacin foods to eat include chicken, liver, tuna, turkey, salmon and legumes.

18. Vitamin B12

Vitamin B12 is critical for red blood cell production and oxygen delivery to the scalp. A deficiency in B12 may contribute to hair thinning, especially in people following plant-based diets where this vitamin may be lacking.

A 2022 case-control study conducted in India explored the relationship between serum vitamin B12 levels and chronic telogen effluvium in humans. The researchers recruited 35 patients (mean age 31) with chronic telogen effluvium and 35 healthy control individuals, measuring their Vitamin B12 concentrations.

They found that 60 percent of those with hair shedding were deficient in B12 compared to only 26 percent in the control group, a difference that was statistically significant.

The authors proposed that because hair matrix cells are among the most rapidly dividing in the body and require DNA synthesis, adequate Vitamin B12 is essential for follicle proliferation. Thus, B12 deficiency may contribute to impaired growth and excessive shedding.

Some of the top B12 foods to eat include beef liver, nutritional yeast, mackerel, beef, cottage cheese, eggs and more. As you can see, B vitamins are some of the most important vitamins for hair growth.

19. Selenium

Selenium acts as an antioxidant and supports thyroid function, which is closely tied to hair health. Both deficiency and excess selenium can lead to hair problems, so optimal balance is key.

A prospective, assessor-blinded, randomized study published in 2023 included 83 adult participants (mean age 41) diagnosed with androgenetic alopecia or chronic telogen effluvium. The researchers evaluated the effects of a supplement containing amino acids, iron, selenium and marine collagen alongside standard treatments compared to standard treatments alone.

Over 12 weeks, the group receiving the selenium-containing supplement exhibited significantly greater improvement on the seven-point Global Assessment Score (GAS), as determined through blinded photographic evaluation. Most patients reported enhanced hair density and reduced shedding compared to controls.

These findings suggest that selenium, in combination with other micronutrients, may potentiate conventional therapy, supporting improved hair growth and clinical outcomes in humans.

In addition to supplements, you can eat selenium-rich foods like nuts, fish, poultry and mushrooms, which also contain several other vitamins for hair growth.

20. Magnesium

Magnesium helps with protein synthesis and stress reduction, both important for hair growth. Chronic stress and low magnesium levels have been linked to telogen effluvium, a form of temporary hair loss.

A randomized, double-blind clinical trial conducted in Iran in 2022 examined the effects of daily oral magnesium supplementation (approximately 96 milligrams/day) over 10 weeks in 64 women diagnosed with polycystic ovary syndrome (PCOS). Among several outcomes, the researchers specifically assessed alopecia, using a validated hair-loss scoring system, at both baseline and study conclusion.

The magnesium group experienced a statistically significant reduction in alopecia scores compared to their baseline, while the placebo group showed no meaningful change.

Although the study’s primary design wasn’t focused on general hair growth, the observed improvement in hair loss suggests that magnesium supplementation may support hair follicle health, potentially through roles in protein synthesis, inflammatory modulation and cellular proliferation.

Foods high in magnesium to eat include wheat bran, amaranth, nuts, seeds and more.

What stops hair growth?

Hair is considered to be a major component of an individual’s general appearance, and the psychological impact of hair loss results in detrimental changes in self-esteem and self-worth. It also affects a large number of people, as up to 50 percent of men are affected by genetic hair loss by the age of 50.

In women, the major cause of hair loss before the age of 50 is nutritional. The main cause of hair loss for women appears to be depleted iron stores, but corrections of these imbalances can stop the excessive hair loss within a few months.

Factors that inhibit hair growth include:

• Poor nutrition
• Hormonal changes
• Family history
• Medications
• Radiation therapy
• Pregnancy
• Thyroid disorders
• Anemia
• Autoimmune diseases
• Polycystic ovary syndrome
• Skin conditions (such as psoriasis and seborrheic dermatitis)
• Stress
• Dramatic weight loss
• Physical trauma

By getting more of the supplements, minerals and vitamins for hair growth mentioned above, however, you can help slow hair thinning and actually promote hair growth.

Frequently asked questions

Do vitamins for hair growth really work?

Vitamins and supplements can help with hair growth if a deficiency is the root cause of hair thinning or hair loss. Nutrients like biotin, zinc, iron, vitamin D and B vitamins play key roles in follicle health and hair production.

However, if your hair loss is due to genetics, hormones or medical conditions (like alopecia areata), vitamins for hair growth may have limited effect.

How do supplements and vitamins for hair growth actually work?

These nutrients support healthy hair by:

• Strengthening hair follicles
• Improving blood flow to the scalp
• Supporting keratin production, the main protein in hair
• Reducing oxidative stress and inflammation, which can damage follicles

For example, vitamin D helps create new follicles, while iron and zinc help deliver oxygen and nutrients to hair roots.

Do vitamins for hair growth make me grow hair everywhere?

No, hair growth vitamins do not stimulate hair growth on the entire body. They support the normal hair cycle primarily on the scalp, where the follicles are more sensitive to hormonal and nutritional changes.

Vitamins for hair growth won’t cause sudden growth on areas like the face, chest or back unless those areas are already hormonally active.

Are there any other side effects of hair growth vitamins?

Yes. While typically safe when used appropriately, some side effects of nutrients and vitamins for hair growth may include:

• Breakouts or acne (especially with high-dose biotin)
• Upset stomach or nausea
• Allergic reactions (rare, but possible)
• Interactions with medications, especially if taking high doses of fat-soluble vitamins or minerals

In addition, over-supplementation of certain nutrients (like selenium or vitamin A) can actually cause hair loss.

What are the best vitamins for hair growth?

Some of the most effective supplements and vitamins for hair growth include:

• Biotin (B7)
• Vitamin D
• Vitamin B12
• Vitamin C
• Iron
• Zinc
• Vitamin A (in moderation)
• Magnesium
• Selenium
• Niacin (B3)
• Riboflavin (B2)

These work together to support follicle strength, scalp health and protein synthesis.

Which supplements are best for hair loss in females?

For women, the most effective hair-supporting supplements often include:

• Biotin
• Vitamin D3
• Iron (especially if menstruating or anemic)
• Zinc
• Collagen peptides
• B-complex vitamins
• Saw palmetto (for hormone-related thinning)
• Ashwagandha (helps with stress-related hair loss)

A comprehensive women’s hair supplement often combines many of these.

Can too much biotin cause hair loss?

Too much biotin is not known to directly cause hair loss, but extremely high doses can:

• Disrupt lab test results (e.g., thyroid, cardiac markers)
• Cause acne-like skin breakouts
• Create nutrient imbalances (e.g., reduce absorption of other B vitamins)

This may indirectly affect hair health, but hair loss from biotin excess is rare.

Can lack of zinc cause hair loss?

Yes. Zinc deficiency is a known cause of hair loss, particularly telogen effluvium, where hair prematurely enters the resting phase.

Zinc plays a key role in follicle health, cell regeneration and sebum regulation on the scalp.

How much magnesium should I take for hair growth?

Magnesium needs vary by age and gender. For adults:

• Women: 310-320 mg/day
• Men: 400-420 mg/day

There’s no specific “hair growth dose,” but taking enough magnesium daily through food or supplementation may support scalp circulation and reduce follicle calcification. Avoid exceeding 350 mg/day of supplemental magnesium unless supervised by a doctor.

What vitamin deficiency causes hair loss the most?

The most common deficiencies linked to hair loss include biotin, iron, vitamin D and zinc. Low levels of vitamin B12, riboflavin and niacin can also contribute.

Can taking too many vitamins cause hair loss?

Yes. Over-supplementing with certain vitamins, such as vitamin A or selenium, may actually trigger hair loss. It’s important to stick to recommended dosages or work with a healthcare provider.

How long does it take for vitamins to improve hair growth?

It typically takes three to six months of consistent supplementation and dietary changes to notice improvements in hair thickness and growth.

Should I take a multivitamin or individual supplements for hair growth?

A high-quality multivitamin that contains key nutrients for hair health is often a good starting point. However, if you have a known deficiency (e.g., iron or B12), targeted supplementation may be necessary.

Is it better to get these vitamins from food or supplements?

Whole foods are ideal because they provide nutrients in their most bioavailable forms, along with other synergistic compounds. However, supplements can help fill in gaps when dietary intake is insufficient.

Are there natural sources of these hair growth vitamins?

Yes. For example:

• Vitamin B2 is in eggs, almonds, spinach
• Vitamin B3 is in turkey, salmon, brown rice
• Vitamin B12 is in beef liver, sardines, eggs
• Selenium is in Brazil nuts, tuna
• Magnesium is in leafy greens, pumpkin seeds, dark chocolate

Final thoughts

• A major contributor to hair loss is poor nutrition, resulting in vitamin deficiencies.
• Studies have shown that women with an iron deficiency are at a higher risk of hair loss, and serum ferritin levels below or equal to 30 milligrams/milliliter are strongly associated with telogen hair loss. Low serum zinc levels have also been linked to alopecia areata cases.
