Vitamin A plays an important role in proper cell growth, which directly influences hair growth. It helps produce the natural oils, also known as sebum, on your scalp. This gives your hair a healthy gloss and shine. Vitamin A contains antioxidants that moisturize the scalp and prevent the hair from drying out. This is one of the best vitamins for hair growth and thickness. It’s important to note that it is possible to get too much Vitamin A, which is going to be counterproductive to your hair growth efforts.[1]

Often referred to as vitamin B complex, all the eight B vitamins (B1, B2, B3, B5, B6, B7, B9, and B12) play a significant role in maintaining us healthy. B vitamins influence our energy, metabolism, nerves, muscles, skin, nails, and hair. As a whole, vitamin B complex increases cell growth and division, which is very important for healthy hair growth. To make sure your body isn’t vitamin B deficient, it’s important to replenish your body’s supply daily.

That’s because this type of vitamin is water-soluble, meaning the body can’t store it. Rather, whatever the body doesn’t use gets flushed out of your system through your urine. Some warning signs of deficiency will be, you will feel weak or tired, will be bruising easily and your hair will not grow as fast as it used to. Vitamin B12 is the most important among the B vitamins, but for best results try to mix them all in your daily diet plan. Again, the best way to load up on B vitamins is through the foods you eat.

Some sources include meats, eggs, nuts, grains, and vegetables. If your diet is lacking in B vitamins, though, you can take a daily supplement. Additionally, some hair care products contain B vitamins for extra support.

Most of us have the knowledge that vitamin C can help to increase our immunity, preventing us against frequent colds and other diseases. What many people don’t know, though, is vitamin C can help us to strengthen our hair and help it to grow. That’s partly because vitamin C helps the body produce collagen, a vital protein for healthy hair, skin, and nails.

Additionally, vitamin C is recognized as an antioxidant that fights free radicals that damage body tissue. Free radicals have been known to damage hair, making it weak and brittle. If you notice your hair breaking a lot or shedding, it may be due to vitamin C deficiency.

While you can simply take a vitamin C supplement, experts say it’s best to load up on nutrients from whole foods. Along with consuming nutritious foods, there are a number of great hair care products that are infused with vitamin C.[1]

Nearly 85% of Americans aren’t getting enough of this important “sunshine” vitamin that promotes healthy follicle growth. One way to boost vitamin D levels is to spend some time outside in the sun. You don’t need that much in order to keep your body synthesizing its own Vitamin D — just around 15-20 minutes every day. While this isn’t difficult during the warm summer months, you may not be able to soak up enough sun during the winter. That’s where supplements and food come into play.[1] [2]

While vitamin E is one of the most overlooked vitamins for hair growth, it’s an antioxidant that repairs and builds tissue, which is essential for healthy hair growth. Along with eating vitamin E-rich foods (such as almonds, seeds, avocado, and broccoli), people are raving about the benefits they reap from its topical use. When you apply vitamin E to your scalp, it helps reduce inflammation, increases blood circulation, boosts oxygen supply, and repairs damaged hair follicles. Officials recommend massaging vitamin E oil into the hair and scalp at least twice a week to promote hair growth.[1] [2]

Niacin is another vitamin that’s in the B family but deserves its own recognition. The Niacin helps to nourish the scalp, promoting healthy hair growth. Without adequate amounts of niacin, your hair stands the chance of becoming brittle, lifeless, and may even fall out.[1]

If you desire longer, healthier hair then doesn’t forget about Biotin. Biotin is rapidly becoming one of the most widely used supplements for faster hair growth. While biotin is a B vitamin it plays such a key role in maintaining hair healthy that it needed its own spot. This vitamin helps produce glucose and break down proteins into amino acids. Since hair itself contains keratin, which is a form of protein, this supports healthy locks. While most people do get enough Biotin from the foods they eat each day, it is a water-soluble vitamin. Again, that means your body can’t retain it and flushes what it doesn’t use. So you need to get enough of it each day or you’ll run a deficit. Many hair care products now contain Biotin. However, that doesn’t mean you should ditch biotin-rich foods or supplements. Rather, a combination of both an internal and external supply seems to work best.[1]

While not a vitamin, iron is an important mineral that your body needs in order to function properly. One way iron[1] benefits the body is by strengthening hair and promoting growth. Without iron, doctors say your hair can become dull, thin, and dry. To find out if you are lacking in iron you can go for a simple blood test.

Fish oil supplements have many benefits, ranging from heart health to mental acuity. The fatty acids found in fish oil are also great for the hair. They help to nourish and strengthen the hair, and they can also help to prevent dandruff and other damaging scalp conditions.[1] That’s because fish oil helps reduce inflammation. If your hair loss is caused by scalp irritation, taking fish oil supplements will help to soothe the scalp and add luminosity to your strands.
So, there is no doubt that few things are better for hair than fish oil supplements. Omega-3, one of the main nutrients that make up fish oil, is well-known for making hair grow longer, stronger, shinier, and healthier. Fish oil is incredibly good for hair. The omega3 fatty acids in fish oil are full of nutrients as well as proteins. These help in keeping the hair healthy.[2]

It is said that if you want to cover your vitamins from A to Zinc and that is certainly a smart choice and if you’re looking for healthy hair growth. A zinc deficiency can weaken your immune system, lead to poor digestive health, throw your hormones out of order, and play a part in lackluster hair growth. The good news is that it’s not too hard to keep up with your zinc requirements. zinc benefits[1]

One noticeable side effect of prenatal vitamins is improved hair growth since the body is getting increased amounts of many of the vitamins that encourage hair growth. However, there are hair growth vitamins that you can buy that are specifically designed to grow hair and will have a vitamin profile geared directly towards hair growth and not geared toward providing proper nutrition for pregnancy.

Compared to not getting adequate supplies of vitamins, it most definitely makes a difference in the health of your hair, and thus, it can be said that vitamins for hair really do help with hair growth. Of course, if you have a hereditary problem or a medical condition that is limiting your hair growth, they may not have an effect. If that’s the case you should seek additional treatment options.[1]
