A healthy diet is essential for feeling good and keeping your hair healthy. Vitamins like Vitamin D, B12, iron, and zinc help strengthen your hair and encourage new growth.
Vitamin deficiencies, particularly in Vitamin D, B12, iron, Vitamin A, Vitamin E, zinc, and folate, can lead to hair loss.
These vitamins play vital roles in hair follicle health, growth, and regeneration. Insufficient levels can result in thinning, shedding, and weakened hair.
This blog will explore the key vitamins linked to hair loss and how to restore healthy hair growth.
Which Vitamin Deficiency Causes Hair Loss: 7 Key Deficiencies
Eating healthy food is not just good for your body. It also helps keep your hair strong and shiny. Vitamins like D, B12, iron, and zinc help your hair grow and stay in shape.
When you don’t get enough vitamins, like Vitamin D, B12, iron, Vitamin A, Vitamin E, zinc, and folate, your hair can start to thin, fall out, or stop growing the way it should. These vitamins are essential for keeping your hair roots (follicles) healthy.
In this blog, we’ll look at which vitamin deficiencies can lead to hair loss and what you can do to fix them.
Vitamin Deficiencies and Hair Loss
Not getting enough of the right vitamins can make your hair fall out or become thin. Let's go through the main vitamins your hair needs to grow properly and stay healthy.
Vitamin D Deficiency and Hair Loss
Vitamin D helps your hair grow. If you don’t get enough, your hair might stop growing and fall out more.
Signs You May Be Low in Vitamin D:
- Hair getting thin or bald spots on your head
- Hair falling out when brushing or washing
- Hair feels dry and breaks easily
Where to Get Vitamin D:
- Sunlight: Your skin makes Vitamin D when you spend time outside.
- Fatty fish: Salmon, mackerel, and sardines
- Fortified foods: Milk, orange juice, and cereals that have Vitamin D added
- Egg yolks
How to Fix It: If you don’t get outside much or don’t eat foods with Vitamin D, you might need a supplement. This is common in places with less sunlight.
Vitamin B12 Deficiency and Hair Loss
Vitamin B12 helps your body make red blood cells, which carry oxygen to your scalp. Your hair needs that oxygen to grow. Without enough B12, your hair can get weak and fall out.
Signs of Low Vitamin B12:
- Hair that breaks or falls out easily
- Pale or yellowish skin
- Feeling very tired or weak
- Trouble breathing
Where to Get Vitamin B12:
- Meat (beef, chicken), fish (like tuna or salmon), and eggs
- Dairy (milk, cheese, yogurt)
- Fortified foods like cereals or plant-based milks for people who don’t eat meat
How to Fix It: If you’re vegan or vegetarian, you might need B12 supplements or fortified foods to stay healthy.
Iron Deficiency and Hair Loss
Iron helps carry oxygen in your blood. Your hair needs that oxygen to grow strong. Without enough iron, your hair may grow slowly or fall out.
Signs of Low Iron:
- Hair thinning, mostly at the top of the head
- More hair is falling out when brushing
- Pale skin and tiredness
- Feeling dizzy or out of breath
Where to Get Iron:
- Red meat, like beef or lamb
- Leafy greens (spinach, kale)
- Beans, lentils, and chickpeas
- Fortified cereals, dried fruit (like raisins), and pumpkin seeds
How to Fix It:
Try to eat more iron-rich foods. Eating foods with Vitamin C (like oranges) can help your body absorb more iron. If your doctor says you're very low on iron, they might suggest a supplement.
Vitamin A Deficiency and Hair Loss
Vitamin A keeps your scalp and hair moisturized by helping your body make sebum (natural oils). Without it, your hair may become dry and break more easily.
Signs of Low Vitamin A:
- Dry, flaky scalp (can cause dandruff)
- Hair that feels dry and breaks easily
- Hair looks dull or grows slowly
Where to Get Vitamin A:
- Orange veggies like carrots and sweet potatoes
- Leafy greens like spinach and kale
- Liver (beef or chicken)
- Egg yolks and dairy products
How to Fix It: Eat more colorful veggies and greens. But don’t take too much Vitamin A too much can also cause hair loss.
Vitamin E Deficiency and Hair Loss
Vitamin E helps protect your hair and makes sure blood flows well to your scalp. This brings nutrients to your hair roots so your hair grows strong.
Signs of Low Vitamin E:
- Hair falls out more than usual
- Dry or itchy scalp
- Hair feels rough or frizzy
Where to Get Vitamin E:
- Nuts like almonds and sunflower seeds
- Oils like sunflower and olive oil
- Green veggies like spinach and broccoli
- Avocados and kiwi
How to Fix It: Eat more Vitamin E-rich foods or try using Vitamin E oil on your scalp. It’s always better to get your vitamins from food than pills.
Zinc Deficiency and Hair Loss
Zinc helps your hair grow by repairing cells and balancing hormones. Without enough, your hair may fall out or grow very slowly.
Signs of Low Zinc:
- Hair thinning, especially near the hairline
- Flaky, dry scalp
- More hair falling out and slow regrowth.
Where to Get Zinc:
- Red meat, like beef
- Seafood like oysters and crab
Pumpkin seeds, cashews - Beans and lentils
- Dairy products like cheese and yogurt
How to Fix It: Add more zinc-rich foods to your meals. If you need supplements, ask a doctor first because too much zinc can cause problems.
How Much Does Treatment Cost?
Folate (Vitamin B9) Deficiency and Hair Loss
Folate helps your body make and fix DNA, including in hair cells. Without it, your hair can become weak and fall out more often.
Signs of Low Folate:
- Looking pale or feeling tired
- Hair falling out or not growing well
- Hair that breaks easily
Where to Get Folate:
- Leafy greens like spinach and kale
- Beans and lentils
- Oranges and other citrus fruits
- Avocados and nuts
How to Fix It: Eat more folate-rich foods. Some people might need a folic acid supplement if they’re not getting enough from food.
How to Fix Vitamin Deficiencies?
Here’s how much of each vitamin adults should get:
- Vitamin D: 600–800 IU
- Vitamin B12: 2.4 micrograms
- Iron: 18 mg for women, 8 mg for men
- Vitamin A: 900 mcg (men), 700 mcg (women)
- Vitamin E: 15 mg
- Zinc: 11 mg (men), 8 mg (women)
- Folate: 400 mcg
Supplements vs. Food: While vitamin pills can help, getting your nutrients from healthy foods like fruits, veggies, whole grains, and lean meats is better. Your body absorbs vitamins better that way.
When to See a Doctor: See a doctor if you’re losing a lot of hair or feel tired, weak, or just not yourself. They can test your vitamin levels and help you figure out what’s wrong.
Conclusion
In summary, several vitamin deficiencies can contribute to hair loss, including Vitamin D, B12, iron, Vitamin A, Vitamin E, zinc, and folate.
It’s important to maintain a balanced diet rich in these nutrients to prevent these deficiencies or take supplements if needed.
If you experience significant hair loss, consulting a healthcare provider can help determine the underlying cause and appropriate treatment.
Frequently Asked Questions
Yes, a vitamin D deficiency can contribute to hair loss. Vitamin D is essential for the creation and activation of hair follicles. Low levels may cause hair follicles to enter a resting phase, resulting in increased shedding and reduced hair growth.
Vitamin B12 is crucial for hair growth as it supports red blood cell production, ensuring hair follicles receive enough oxygen. To prevent B12 deficiency, include animal products such as meat, fish, eggs, or fortified foods. Vegetarians and vegans may need B12 supplements.
Iron plays a vital role in oxygenating hair follicles. Good sources of iron include red meat, leafy greens like spinach and kale, legumes like lentils, and fortified cereals. Pairing iron-rich foods with vitamin C (e.g., citrus fruits) can improve iron absorption.
Yes, restoring adequate levels of the necessary vitamins through diet or supplements can help rejuvenate hair growth. In many cases, improving nutrient intake leads to healthier, stronger hair. However, it's essential to consult a healthcare provider for personalized advice.
