If you are looking for ways to improve your hair health, you might have come across various products that claim to be hair vitamins. But what are hair vitamins exactly, and do they really work as one of the best hair supplements for your thinning hair?


Type of Vitamins Your Body Need for Healthy Hair Growth

Our body actually needs various vitamins daily to keep our body and hair healthy. Taking hair growth vitamins helps in promoting hair growth and strength. Generally, these are the common vitamins you need to prevent hair loss:


A type of vitamin B that is involved in the production of keratin, the protein that makes up hair.

Vitamin C

An antioxidant that helps protect hair from damage caused by free radicals and environmental factors.

Vitamin E

Another antioxidant that also improves blood circulation to the scalp and hair follicles.


A mineral that helps deliver oxygen to the hair cells and prevents hair loss due to iron deficiency anaemia.


A mineral that regulates hormone levels and prevents hair thinning and shedding.

However, not all hair vitamins are created equal. Some may contain other ingredients that are not proven to benefit hair health, such as collagen, silica, or amino acids. Some may also have high doses of certain nutrients that can cause side effects or interact with other medications.


Hair Vitamins vs Hair Growth Vitamins

Many people wonder what the difference between hair growth vitamins and normal hair vitamins is. Hair growth vitamins are supplements that contain specific nutrients that are known to promote hair growth, such as biotin, zinc, iron, vitamin B12, and folic acid. Normal hair vitamins are supplements that contain general nutrients that are good for overall health and wellness, such as vitamin C, vitamin E, omega-3 fatty acids, and antioxidants.

The main difference between hair growth vitamins and normal hair vitamins is that hair growth vitamins target the hair follicles and the scalp, while normal hair vitamins support the whole body and the immune system. Hair growth vitamins may help stimulate the production of keratin, which is the protein that makes up hair strands, and improve blood circulation to the scalp, which may nourish the hair follicles and prevent hair loss. Normal hair vitamins may help protect the hair from environmental damage, such as UV rays, pollution, and stress, and prevent oxidative stress, which may cause premature aging and graying of the hair.

Both types of vitamins can be beneficial for hair health, but they have different purposes and effects. Hair growth vitamins are more suitable for people who want to increase the length, thickness, and density of their hair, or who suffer from hair thinning or balding. Normal hair vitamins are more suitable for people who want to maintain the quality, shine, and strength of their hair, or who have healthy hair but want to prevent future problems. Depending on your goals and needs, you may choose to take one or both types of vitamins, but always consult your doctor before starting any supplement regimen.


Can I use Vitamins for Hair Growth if I have an Oily Scalp?

As vitamins that support hair growth often come in pills and in oil form, many people that have oily scalp often doubt if they are suitable to get this type of hair growth supplements. Technically, an oily scalp is a condition that occurs when the sebaceous glands produce excess sebum, which can clog the pores and cause inflammation, itching, and dandruff. Oily scalp can also affect the quality and health of the hair, making it look greasy, limp, and dull.

So, is oily scalp people suitable to use hair vitamins? The answer is not straightforward, as it depends on several factors, such as the type and dosage of the hair vitamins, the underlying cause of the oily scalp, and the individual's hair care routine. Some hair vitamins may be beneficial for oily scalp people, while others may worsen the condition or have no effect at all. Therefore, it is important to consult a doctor or a dermatologist before taking any hair vitamins, especially if you have a medical condition or are taking other medications that may interact with them. Some general tips for oily scalp people who want to use hair vitamins are:

Choose hair vitamins that contain antioxidants, such as vitamin C, vitamin E, and zinc

These nutrients can help reduce inflammation and oxidative stress in the scalp, which may contribute to sebum overproduction.

Avoid hair vitamins that contain biotin, vitamin B6, or vitamin B12

These nutrients are involved in the metabolism of fats and proteins, and may increase sebum production in some people.

Take hair vitamins with food and water

This can help prevent nausea and stomach upset, which are common side effects of some hair vitamins.

Follow a balanced diet and drink plenty of water

Eating a variety of foods that provide essential nutrients for hair health, such as protein, iron, omega-3 fatty acids, and silica, can help support the effects of hair vitamins. Drinking water can help flush out toxins and excess sebum from the body and the scalp.

Maintain a good hair care routine

Washing your hair regularly with a mild shampoo that is designed for oily scalp can help remove excess oil and dirt from the scalp and the hair. Avoid using harsh chemicals or styling products that can irritate the scalp or weigh down the hair. Use a conditioner only on the ends of the hair, not on the scalp. Dry your hair gently with a towel or a blow dryer on low heat. Brush your hair gently with a wide-toothed comb or a boar bristle brush to distribute the natural oils evenly along the hair shaft.

Hair vitamins can be a helpful addition to your hair care regimen if you have oily scalp, but they are not a magic solution. You need to use them wisely and carefully, and monitor your results. If you notice any adverse effects or no improvement in your hair condition after using hair vitamins for several weeks or months, you should stop taking them and seek professional advice.


How to Pick the Right Vitamins for Hair Growth for Yourself?

As we mentioned above, if you want to improve your hair health and growth, you might be interested in trying a hair growth vitamin, but often having a hard time to pick the right one as we don't usually know our hair well. Here is a step-by-step guide on how to use a hair growth vitamin:

Consult your doctor before taking any supplements, especially if you have any medical conditions or allergies.

Your doctor can advise you on the best dosage and possible interactions with other medications or supplements.

Choose a hair growth vitamin that suits your needs and preferences.

There are many brands and formulas available, so do some research and read reviews before buying. Some factors to consider are the ingredients, the price, the taste, and the customer service.

Follow the instructions on the label of your hair growth vitamin.

Usually, you will need to take one or two capsules or gummies per day, preferably with a meal. Do not exceed the recommended dose, as this may cause side effects or toxicity.

Be consistent and patient with your hair growth vitamin.

It may take several weeks or months to see noticeable results, depending on your hair type and condition. Keep track of your progress by taking pictures or measuring your hair length every month.

Combine your hair growth vitamin with a healthy diet and lifestyle.

A hair growth vitamin is not a magic pill that will solve all your hair problems. You also need to eat well, drink enough water, exercise regularly, reduce stress, and avoid heat styling and harsh chemicals on your hair.

How to Make Hair Growth Vitamins Work As Intended?

While hair vitamins may sound like a quick and easy solution to your hair problems, they are not a magic bullet. If you are considering to get them simply because of these reasons, you might want to look for other ways to improve your hair growth cycle instead:

I need hair vitamin because they can make my hair grow faster

The truth is, there is no evidence that any supplement can increase the rate of hair growth, which is determined by genetics and other factors. The average hair growth rate is about half an inch per month, and nothing can change that.

I take them because I believe they can make my hair thicker and fuller

This fact is debatable as the thickness and density of your hair are also influenced by genetics and age. Hair vitamins may help prevent hair loss due to nutrient deficiencies, but they cannot reverse or prevent hair loss due to other causes, such as hormonal changes, stress, or medical conditions.

I need them to make my hair shinier and smoother!

Healthy hair doesn't come by easily. The appearance and texture of your hair are still largely determined by how you care for it externally. Hair vitamins may help improve the quality of your hair from within, but they cannot replace proper hair care practices, such as washing, conditioning, moisturising, and protecting your hair from heat and chemicals.


Eat the Right Food To Increase Your Hair Density

In order to achieve the 3 objectives mentioned above, while hair vitamins may provide some benefits for your hair health, they are not a substitute for a balanced diet and a healthy lifestyle. Here are some of the alternatives to have healthy hair:

* Eat a variety of foods that are rich in protein, iron, zinc, vitamin C, vitamin E, and other nutrients that support hair health. Some examples are eggs, lean meat, fish, nuts, seeds, beans, fruits, vegetables, and whole grains. * Drink plenty of water to keep your body and your hair hydrated. * Avoid smoking, excessive alcohol consumption, and stress, which can damage your hair and cause it to fall out. * Limit the use of heat styling tools, such as blow dryers, curling irons, and flat irons, which can dry out and damage your hair. If you do use them, apply a heat protectant product beforehand and use the lowest temperature setting possible. * Trim your hair regularly to get rid of split ends and keep your hair healthy. * Use gentle products that suit your hair type and condition. Avoid harsh chemicals, such as sulphates, parabens, and silicones, which can strip your hair of its natural oils and moisture. * Protect your hair from sun exposure by wearing a hat or using a sunscreen spray for your hair. * Last but not least, the right hair regrowth treatment.


How Perfect Medical Can Complement Your Healthy Hair Plan

Even the best hair growth vitamins won't be able to keep your good hair day permanent. You will need a healthy scalp to complement with the other hair growth supplement you take, and the F8 Hair Regrowth Treatment is here to help. This all-natural, risk-free approach of maintaining a healthy scalp and hair. Sweeping low-level laser radiation across the scalp activates dormant hair follicles and fortifies the interior hair papilla. In addition to reawakening latent hair follicles, the serum and revitalising nutrients help strengthen capillaries and enhance microcirculation.

This process won't hurt you, so there won't be any wounds. The low-energy laser speeds up blood flow without hurting the skin too much. After the process, hair growth serum will be put on the scalp to keep it moist and stop sebum from getting in the way. So, the scalp will feel refreshed and fed, which will keep hair and scalp problems from happening again. This means that after treatment, both the thickness and quality of your hair will improve!



Hair vitamins are supplements that contain nutrients that may help improve your hair's health. However, they are not a miracle cure for all your hair woes. They cannot make your hair grow faster, thicker, fuller, shinier, or smoother. They can only supplement what you already have and prevent nutrient deficiencies that can cause hair loss. To have healthy hair, you need to eat well, drink water, avoid stress and bad habits, take care of your hair externally, and consult a doctor if you have any medical issues that affect your hair.

1. What is folic acid and why is it important for hair growth?

Folic acid, also known as folate or vitamin B9, is a water-soluble vitamin that helps your body make new cells, including hair cells. Folic acid also plays a role in DNA synthesis and repair, which can affect hair growth and health. Folic acid deficiency can cause hair loss, thinning, graying and other problems.

2. How can I get thicker hair with dietary supplements?

There is no conclusive evidence that any dietary supplement can directly make your hair thicker. However, some supplements may support your overall hair health and growth by providing essential nutrients, such as biotin, iron, zinc, omega-3 fatty acids and collagen. These nutrients may help prevent or correct deficiencies that can cause hair loss or damage.

3. Are dietary supplements safe and effective for hair health?

Dietary supplements are not regulated by the Food and Drug Administration (FDA) in the same way as drugs. This means that their safety, quality and effectiveness are not guaranteed. Some supplements may contain contaminants, allergens, fillers or incorrect dosages that can harm your health. Some supplements may also interact with other medications or conditions you have. Therefore, you should always consult your doctor before taking any supplements and follow the label instructions carefully.

4. What is vitamin D deficiency and how does it affect hair health?

Vitamin D is a fat-soluble vitamin that helps your body absorb calcium and phosphorus, which are important for bone health. Vitamin D also regulates the expression of genes involved in hair follicle development and cycling. Vitamin D deficiency can cause rickets, osteomalacia, muscle weakness and increased risk of infections. Vitamin D deficiency can also cause hair loss, thinning, brittleness and slow growth.

5. What is horsetail extract and how does it help with hair health?

Horsetail extract is a herbal supplement derived from the horsetail plant (Equisetum arvense), which is rich in silica, a mineral that helps strengthen hair strands and prevent breakage. Horsetail extract also has anti-inflammatory, antioxidant and antimicrobial properties that may help with scalp health and hair growth. However, there is limited research on the safety and effectiveness of horsetail extract for hair health, so you should use it with caution and under medical supervision.
