I totally get how you feel when you see more hair on your brush than you’d like—been there, done that, and it’s not fun. I’ve actually had my own battle with hair loss due to vitamin deficiencies, and let me tell you, it’s been quite an eye-opener.

So, I’ve been digging into the world of vitamins because, honestly, they can be total game-changers for our hair. I’ve learned so much about how the right ones can give our thinning hair a serious boost from the inside.

I’m excited to share with you the seven essential vitamins for thinning hair that have made a real difference for me. We’re talking about the good stuff here—biotin, Vitamin E, and Vitamin D—these are like superheroes for anyone dealing with fine or thinning hair.

This isn’t just some guide; it’s a collection of real info that’s helped me turn things around for my hair. And I’m pretty stoked to pass on these nuggets of wisdom to you. So, let’s jump in together and explore these vitamins. I’m here to walk you through it all like a friend who’s got your back.

Common Causes Of Hair Loss

There are different causes of hair loss (also known as alopecia), and it is important to find out which causes you to lose hair. So, first things first, we need to fully grasp the many different causes of hair loss before checking on hair vitamins for thin hair.

Hair loss can happen due to many variables, such as genetic factors or predisposition, vitamin and mineral deficiencies, skin problems, hair growth disorders, poor diet, hormonal problems, certain internal diseases, drug use, stress and depression, cosmetic factors, childbirth, and the chemotherapy process[1].

In my case, I considered these causes and could stripe off some things that weren’t related to me (for example, I’m young, I don’t do drugs, I haven’t had a child or chemotherapy). I normally have thick hair, so when I saw my hair thinning, I knew something was off, but not exactly what yet. I decided to ask my doctor to do a blood test (to see if we could find any deficiency. Bingo! My vitamin D and B12 were too low.

I recommend seeing a doctor and asking to get your bloodwork done, especially if you think it could be a vitamin or mineral deficiency. This will help evaluate what you need to get those healthy locks back.

7 Essential Vitamins For Thinning Hair To Prevent Hair Loss

10 Essential Vitamins For Thinning Hair

Among the about 100,000 hair follicles on the human scalp, 90% are in the anagen phase without alopecia. These follicles require critical nutrients, including proteins, vitamins, and minerals, to create healthy hair[2]. So, which vitamin deficiency causes hair loss?

Vitamin D

When your body lacks Vitamin D, your hair might become dry and brittle, prone to breakage. You might also notice more hair shedding than usual, and even premature graying could occur. Luckily, diagnosing this deficiency is as simple as a blood test.

Treatment typically involves daily Vitamin D supplements, but getting the right dosage from your healthcare provider is crucial to avoid any side effects. Other ways to boost your Vitamin D levels include soaking up some sun and adding foods like fatty fish and fortified dairy to your diet.

Vitamin A

If you’re running low on Vitamin A, your hair might start to thin out, and you might experience more shedding. Dandruff can also become a nuisance. A blood test can confirm if you’re lacking in this essential vitamin.

But there’s good news – you can reverse a Vitamin A deficiency. Supplements can help, but it’s essential to consult with a doctor, especially if you’re pregnant. Adding orange and yellow vegetables like carrots, sweet potatoes, squash, green peppers, and dark leafy greens, along with cod liver oil, to your diet can also make a difference.

Vitamin E

Low levels of Vitamin E might lead to increased hair shedding and thinning. Your hair could become dry and prone to breakage. A blood test can help confirm if you’re not getting enough of this vital nutrient.

Thankfully, Vitamin E deficiency is correctable. Supplements can boost your levels, and foods like sunflower seeds and almonds can provide natural sources. Applying oils like olive or rosehip oil can also help nourish your hair and scalp.

Vitamin C

Without enough Vitamin C, your hair might become dry and prone to splitting. Shedding could increase, and regrowth might take longer than usual. A blood test can determine if your levels are low.

To correct a deficiency, consider daily supplements and adding more Vitamin C-rich foods to your diet, like citrus fruits and broccoli. Topical applications of Vitamin C may also offer benefits.

Folic Acid (Vitamin B9)

Folic acid, or Vitamin B9, is crucial for healthy cell growth, including hair follicles. Low levels can result in increased hair loss and slow regrowth. Blood tests can detect this deficiency.

The good news is that you can fix a folic acid deficiency through diet and supplements. Tablets can help, and foods like leafy greens and citrus fruits are excellent sources.

Biotin (Vitamin B7)

Biotin, also known as Vitamin B7, is essential for healthy hair growth. It’s involved in the production of keratin, a protein that forms the structure of your hair. Low levels can lead to thinning and shedding. While its effectiveness in treating hair loss without a deficiency is debated, ensuring you get enough through sources like whole grains, eggs, and nuts is important.


Zinc deficiency can impair various processes crucial for healthy hair, leading to thinning and increased shedding. Boost your intake through foods like oysters and spinach, and consider supplements under medical supervision.

Vitamin B6

Vitamin B6 plays a vital role in hair health, and a deficiency can lead to thinning or increased hair loss. Doctors can diagnose a vitamin B6 deficiency through blood tests. Boost your levels through foods like poultry and bananas, along with supplements if necessary.


Low iron levels can cause increased hair shedding and stunted growth. Doctors can diagnose iron deficiency through a blood test screening serum ferritin levels – readings below 30 ng/mL often indicate deficiency[3]. Boost your intake with iron supplements and iron-rich foods like red meat, beans, spinach, fortified grains, and lentils.


Essential fatty acids are essential for scalp health and can combat dryness and brittleness in hair. Ensure you get enough through supplements like fish oil capsules and foods like salmon and walnuts.

Do Hair Growth Vitamins Help To Prevent Hair Loss?

As we already talked about, when it comes to preventing hair loss, there’s no one-size-fits-all answer. That said, the role of vitamins and a well-balanced diet cannot be overstated.

Vitamins like B vitamins (including biotin or B7) and minerals play a crucial role in maintaining the overall health of your hair. They’re involved in producing red blood cells, which carry oxygen and nutrients to the scalp and hair follicles. This process is key for hair growth and strength and prevents hair from falling out.

Biotin supplementation has been widely discussed and recommended for those with thinning hair. It’s known for strengthening nails and hair, making it a popular ingredient in many hair growth supplements. However, it’s essential to approach supplementation under the guidance of healthcare professionals or a board-certified dermatologist to ensure you’re addressing your needs without going overboard.

A key to effective hair growth and prevention of hair loss lies in a holistic approach that includes nutrition, avoiding harsh hairstyles, and sometimes, the use of specialized shampoos containing ingredients like saw palmetto or ketoconazole, which have been linked to hair preservation[4][5].

Are Hair Growth Supplements Safe?

If you’re like me and many of my friends, you might be eyeing those hair growth supplements, wondering whether they’re the golden ticket to healthy hair. But here’s the million-dollar question: Are they safe?

First up, it’s critical to understand that hair growth supplements are regulated as foods by the U.S. Food and Drug Administration (FDA). This means manufacturers aren’t required to show proof of safety, quality, or efficacy before their products hit the shelves. Sounds a bit unsettling, right?

That’s why opting for third-party tested supplements can offer some peace of mind by ensuring the product contains what it says on the label without nasty surprises.

Another point worth noting is that taking certain vitamins in high doses may lead to symptoms of toxicity. It’s a classic case of too much of a good thing turning bad. Multivitamins and mineral supplements can be safe for healthy individuals as long as they stick within the recommended daily allowance (RDA).

Moreover, if you’re dealing with specific conditions like alopecia areata, working with healthcare professionals or a board-certified dermatologist is your best bet. They can offer tailored advice and may suggest treatments beyond nutrition and supplements.
