Hair loss is a common problem among women and men. In this article, we will discuss the best vitamins for hair growth in 2021. These vitamins are very effective in promoting hair growth.

Many vitamins can help hair grow faster and more robust. However, not all of them work the same way. This is why it’s essential to find the right one for you. In this blog post, we will discuss the best vitamins for hair growth in 2021.

Hair loss is a common problem among men and women. It can happen at any age, but it’s more common in middle-aged or older people.

There are several reasons why hair loss occurs. Some of these reasons include genetics, stress, poor nutrition, hormonal imbalances, and medical conditions.

If you’re experiencing hair loss, there are ways to prevent further hair loss and promote hair growth. In this article, we’ll discuss the best vitamins for hair growth in 2021.

These vitamins have been proven to be safe and effective when used as directed by your doctor. They also won’t cause side effects like other medications to do.

The following list includes some of the most popular vitamin supplements on the market today:

Vitamin A

This vitamin has long been known for its ability to improve skin health. Vitamin A helps keep scalp cells healthy, so they produce new hairs.

It may take up to three months before you notice results from using vitamin A. It would help if you used retinol only under the supervision of a dermatologist.

You can get vitamin A through food sources such as liver, eggs, milk, fish oil, broccoli, spinach, carrots, sweet potatoes, kale, tomatoes, oranges, and red peppers.


This nutrient promotes cell metabolism, which improves overall energy levels. Biotin works with biotin receptors found throughout the body.

When taken orally, Biotin increases blood flow to the scalp. As a result, nutrients reach the follicles, where they stimulate hair growth.

Some foods rich in Biotin include nuts, seeds, whole grains, dairy products, beans, peas, lentils, soybeans, bananas, avocados, cabbage, cauliflower, Brussels sprouts, eggplant, mushrooms, oats, wheat germ, almonds, cashews, sunflower seeds, pumpkin seeds, sesame seeds, and walnuts.


Many studies show calcium plays an essential role in maintaining strong bones. Calcium deficiency leads to brittle bones. When applied topically, calcium stimulates hair follicle production.

To ensure adequate calcium intake, eat plenty of leafy green vegetables, low-fat yogurt, cheese, tofu, fortified cereals, orange juice, skimmed milk, salmon, shrimp, oysters, clams, crab meat, and lean cuts of beef.


This mineral supports proper thyroid function. Chromium deficiencies lead to weak nails and thinning hair.

In addition to improving nail strength, chromium strengthens connective tissue in the scalp. The result? Healthy hair grows longer and thicker.

Foods high in chromium include brewer’s yeast, brown rice, blackstrap molasses, avocado, chicken breast, turkey, tuna, lobster, pork loins, lamb chops, shellfish, and cod.


This mineral keeps oxygen moving around the body. Iron deficiency causes fatigue, weakness, and dizziness. If left untreated, iron deficiency can even lead to death.

A lack of iron affects both male and female hormones. Women experience irregular menstrual cycles while men suffer from decreased sperm count.

Women often develop iron deficiency due to pregnancy, childbirth, breastfeeding, heavy periods, excessive bleeding during menstruation, and certain diseases, including cancer, diabetes, heart disease, kidney failure, multiple sclerosis, rheumatoid arthritis, and lupus. Menstrual irregularities are also typical among women who have had their ovaries removed or damaged by chemotherapy treatments. Menopausal symptoms like hot flashes and night sweats can cause them to lose interest in sex.

If your diet lacks iron, it won’t be easy to absorb enough when taking supplemental vitamins. To avoid this problem, consume at least 18 mg per day. This amount comes from two servings of dark-meat poultry each week, along with one serving of seafood every other week. Other good sources of iron include dried apricots, barley, Brazil nuts, chickpeas, collard greens, figs, prunes, raisins, strawberries, turnip greens, and white beans.

Folic Acid

This water-soluble vitamin aids in DNA synthesis. Folate is essential because it encourages normal cell division. Inadequate folate consumption can lead to congenital disabilities.

Consuming folic acid daily reduces the risk of neural tube defects in babies born to mothers deficient in folate. NTDs affect about 1 out of 2,000 births.

Other benefits of consuming more folic acid include preventing cardiovascular problems, reducing the risk of colon cancer, promoting bone development, helping avert depression, and protecting against Alzheimer’s disease.

Check price at Amazon

When selecting a hair vitamin, you want something that will provide the most benefit but without the usual risks of using synthetic chemicals.

Tress Luminous uses vitamins and herbal ingredients to boost hair growth, but the overall numbers don’t paint a clear picture of whether this supplement provides reliable health benefits.

On top of that, the per-capsule dosage of the herbal extracts is in the middle of the road, so they may not be able to make as big of a difference as you’d hope for.

8. SugarBearHair Hair Vitamins

Check price at Amazon

SugarBearHair makes a hair growth vitamin that provides only vitamin and mineral ingredients, without the herbal compounds found in other hair products.

Hair Rush’s proprietary hair growth blend contains nearly a dozen different ingredients. The mix includes Biotin, which has already shown evidence of hair growth in multiple studies, including one published in the journal Dermatologic Surgery. However, the amounts of all ingredients in the blend are tiny.

Who should buy vitamins for hair growth?

A deficiency may cause hair loss, hair brittleness, or poor hair strength in vitamins that help hair grow. Men and women both can suffer from hair loss or hair brittleness.

The best way to combat these issues is through supplementation. Many people get better results if they take several different types of nutrients together rather than just one type. For example, you might consider supplementing Biotin, Vitamin C, Zinc, Magnesium, Selenium, Copper, Manganese, Iodine, and Potassium. These supplements work well as part of a multi-vitamin/mineral formula.

While you can examine the micronutrients in your diet and attempt to figure out the deficiencies, often, it’s more convenient to use a vitamin supplement for hair growth. An accessory specifically designed to contain vitamins such as Biotin, B-complex vitamins zinc, iron, and copper can tackle the most frequent nutritional deficiencies responsible for your hair’s weakening.

When your hair plays a major aspect in your appearance, vitamin A that promotes hair growth is a simple method to ensure that you’ve got all your needs covered to make sure you’re getting the best hair you can get. Senior men (and females) who are beginning to lose hair may benefit from a vitamin to increase hair growth.

It is important to stress that a supplement for hair growth isn’t an alternative to the treatment for hair loss. Supplements that contain nutrients for hair growth could give your body the essential building blocks to create healthy and quality hair. However, it doesn’t tackle the root causes of hormonal imbalance that lead to hair loss in the first place.

To do this, you’ll need the best hair loss treatment such as finasteride or minoxidil (or better, both simultaneously). After you’ve had this taken care of, taking a supplement for hair loss can make sure that your body is equipped with all the ingredients it requires to ensure that your hair is healthy and strong.


Hair loss is common among men and women, especially during middle age. There are several reasons why hair loss occurs, such as genetics, stress, hormonal changes, and medications. However, some vitamins can help prevent hair loss. Vitamin B12 helps maintain healthy hair follicles, while vitamin D promotes strong bones and teeth.

Hair supplements can be a great help if you want to grow stronger, healthier hair. They contain the nutrients your body needs to make healthy hair. Vitamins and minerals are necessary for creating healthy hair follicles.

Vitamins also promote blood flow to the scalp, which keeps hair looking fuller and thicker. If you have thinning hair, try adding extra vitamins into your daily routine. You should eat foods rich in specific vitamins every day. Some examples include:

Biotin – Helps strengthen nails and skin

Biotin is a vitamin that helps strengthen nails and skin. This vitamin is found in eggs, milk, cheese, yogurt, and meat. It’s recommended that adults consume about 30 micrograms per day.

Zinc – Promotes nail health

This mineral is necessary for maintaining healthy fingernails and cuticles. Adults require approximately 15 milligrams each day. Good sources include oysters, beef liver, pumpkin seeds, almonds, cashews, sunflower seeds, broccoli, beans, peas, lentils, wheat germ, whole grains, nuts, and dairy products milk and cheese.

Iron – Keeps hair shiny

If you don’t get enough iron regularly, your hair will look duller and thinner over time. Iron deficiency leads to brittle hair because it makes the strands weaker. The good news is that there are many ways to boost your iron intake without having to go overboard on red meats. Try eating spinach, barley, blackstrap molasses, raisins, dried apricots, prunes, soybeans, kidney beans, chickpeas, tofu, dark chocolate, and oatmeal.

Copper – Boosts hair color

You probably already know how much copper affects your taste buds and brain. But did you realize that it has other benefits? One study showed that those who consumed higher amounts of copper were less likely to lose their hair. Researchers believe that copper works by protecting cells against oxidative damage. Oxidation damages DNA, so when you preserve your DNA, you keep your hair growing longer!

Folic Acid – Prevents alopecia

Alopecia means “hair loss.” Folic acid prevents baldness by helping build new hairs. A lack of folic acid causes anemia, which results in weak hair growth. To avoid getting too little folic acid, take 400 mcg of folate from food sources like leafy greens, legumes, bananas, oranges, strawberries, avocados, tomatoes, carrots, sweet potatoes, and mushrooms.

Calcium – Builds strong bones

When calcium levels drop below average, bone density decreases. Calcium plays a role in building strong bones. When you’re deficient in calcium, your body may not produce enough testosterone, leading to a low sex drive. Low testosterone levels cause hair loss. So, boosting your calcium intake could lead to more robust locks. Eat lots of fish, green vegetables, fortified cereals, and dairy products.

Magnesium – Lowers risk of heart disease

A high-fat diet increases cholesterol levels, which puts your cardiovascular system at greater risk of developing atherosclerosis. Magnesium lowers bad LDL cholesterol and triglycerides, which reduces your chances of suffering a stroke or heart attack. Magnesium also improves insulin sensitivity, which protects your body from diabetes.

Selenium – Protects against cancer

Cancerous tumors often develop due to genetic mutations caused by free radicals. Free radicals are molecules containing oxygen atoms that easily react with other substances. Selenium helps prevent these reactions, thus reducing the likelihood of tumor development. It’s found naturally in seafood such as shrimp, tuna, salmon, cod, crab, lobster, scallops, clams, mussels, sardines, anchovies, mackerel, herring, squid, and octopus.

Vitamin B12 – Helps maintain energy levels

The nervous system relies heavily on vitamin B12 for proper functioning. If you have trouble keeping up with daily tasks, this nutrient can help improve concentration and memory. Vitamin B12 is abundant in meat, eggs, dairy foods, and some types of fish. However, if you eat no animal protein, then you’ll need supplements.

Omega 3 Fatty Acids – Promotes scalp health

Your skin needs omega fatty acids to stay hydrated and plump. Omega 3 fats promote cell turnover in the epidermis and dermis. This keeps your skin looking young and supple. You can find them in oily fish like salmon, trout, halibut, mackerel, bluefish, and sablefish. They’re also available in flaxseed oil, walnuts, chia seed, hemp seed, and algae.

Zinc – Improves immune function

Zinc strengthens immunity by improving T-cell activity. Your immune system fights off infections and diseases, but zinc deficiencies weaken its ability to do so. The mineral supports wound healing and tissue repair. It has been shown to reduce scar formation after surgery.

Side effects

Fortunately, many of the key ingredients in a good hair growth vitamin are not known to cause harm, even at high doses. But there are still risks associated with taking specific vitamins. Some people experience side effects when they consume large amounts of certain nutrients. For example:

Iron overload – Iron deficiency is common among women who use oral contraceptives because their bodies don’t absorb iron well. Taking extra iron will increase absorption rates. However, too much iron can be toxic, causing symptoms including nausea, vomiting, diarrhea, abdominal pain, headache, fatigue, weakness, palpitations, shortness of breath, confusion, dizziness, vision problems, and seizures. Symptoms usually resolve once the excess iron is eliminated through urine or stool.

Folate toxicity – High intakes of folates can result in severe headaches, depression, irritability, insomnia, muscle twitching, numbness, tingling, tremors, convulsions, coma, and death. Women should limit their consumption of folate-rich foods to 300 micrograms per day. Men shouldn’t exceed 600 micrograms per day; pregnant women should restrict themselves to 500 micrograms per day while breastfeeding.

It is difficult to determine precise dosing guidelines within no direct clinical trials measuring the effects of vitamins for hair grones. Experts recommend starting low and gradually increasing dosages until you notice an improvement. To avoid overdosage, start with one capsule twice a week and work upward from there.

Biotin and pantothenic acid can be taken several times their recommended daily intake. Intake should likely be high if you think you have a deficiency affecting your hair. There’s little evidence showing whether other vitamins play any role in promoting healthy hair growth. The best way to get all these essential nutrients into your diet is to eat plenty of fruits and vegetables. These contain antioxidants, which help protect cells against free radical damage. Antioxidants may slow down aging processes as we age, and they may prevent some types of cancer. Eating lots of fresh produce helps ensure that you meet your nutrient requirements without having to take supplements.

Vitamin A

Retinoic acid is used to treat acne vulgaris and psoriasis. It works by stimulating keratinocyte proliferation and differentiation. Vitamin A also increases sebum production, helping keep pores clear. However, retinoic acid isn’t approved by the FDA for treating alopecia.

It might seem counterintuitive to apply something that causes more pimples to your head. Still, research shows that topical retinoic acid improves hair loss caused by chemotherapy drugs such as cyclophosphamide. Retinoic acid applied topically stimulates stem cells in the follicle bulge area, where new hairs grow out.

Pantothenic Acid

This B complex vitamin promotes normal blood sugar levels and energy metabolism. Pantothenic acid plays a vital role in maintaining proper hormone balance. It also aids in protein synthesis and DNA replication.

A study published in 2009 found that menopausal women who took 400 milligrams of pantothenic acid each day experienced significantly thicker hair than those who didn’t supplement. This suggests that pantothenic acid could potentially promote hair regrowth after male pattern baldness has been treated.

A 2011 review concluded that although studies on vitamin D supplementation are limited, “it seems reasonable to assume that vitamin D3 would improve the overall quality of life in patients with alopecia.” Many dermatologists prescribe vitamin D supplements for people suffering from alopecia. But this doesn’t mean that taking too much vitamin D will cause hair loss — only that it won’t hurt.

The amount of vitamin D needed varies based on skin pigmentation, season, sun exposure, and body mass index. Experts suggest getting 10 to 15 minutes of sunlight every day between 10 AM and 3 PM for most adults. If you live somewhere sunny year-round, you probably already get enough natural vitamin D. Otherwise, consider sunscreen when going outside during peak hours.


In 2008, researchers reported that calcium was effective in preventing female pattern hair loss. Calcium stimulates cell division and prevents apoptosis. As a result, calcium-rich foods increase the number of active hair follicles.

Calcium citrate or dicalcium phosphate is often added to food products because it gives them a pleasant taste. You don’t need to worry about consuming too much calcium; the RDA for adult males is 1,000 mg per day while females require 700 mg. Women over 50 years old should consume even less: 500 mg per day.
