Healthy and Strong Hair Foods: 14 Nutrient Rich Choices for Hair Health

What Are the Best Healthy and Strong Hair Foods?

A practical list of Healthy and Strong Hair Foods includes:

1. Eggs
2. Salmon and trout
3. Chicken and turkey
4. Lean beef
5. Lentils
6. Beans and chickpeas
7. Plain Greek yogurt
8. Tofu and soy foods
9. Spinach and other leafy greens
10. Bell peppers, berries and citrus fruit
11. Oysters and other seafood
12. Almonds and walnuts
13. Pumpkin, chia and other seeds
14. Sweet potatoes and carrots

These foods provide useful combinations of protein, iron, zinc, vitamin C, vitamin D, biotin, healthy fats, and other nutrients.

You do not need all 14 every day.

Variety across the week matters more.

How Does Nutrition Affect Hair Health?

Hair grows from follicles inside the skin.

These follicles contain living cells.

Living cells need energy and nutrients.

Hair Is Mostly Protein

The visible hair shaft is largely made of a protein called keratin.

Your body therefore needs adequate dietary protein.

Blood Supplies the Follicle

Iron is needed to make hemoglobin.

Hemoglobin helps red blood cells carry oxygen throughout the body.

Many Nutrients Are Involved

Healthy follicles also depend on normal amounts of:

• Zinc
• Vitamin D
• Biotin
• Vitamin B12
• Folate
• Essential fatty acids
• Other vitamins and minerals

More Is Not Always Better

A deficiency can be a problem.

Excessive supplementation can also be a problem.

AAD warns that too much of some nutrients can actually contribute to hair loss.

1. Eggs

Eggs are a useful food for hair nutrition because they provide high quality protein.

They also provide several vitamins and minerals.

Eggs Provide

• Protein
• Biotin
• Vitamin B12
• Selenium
• Some vitamin D

What About Biotin?

Eggs are often promoted as a hair growth food because they contain biotin.

Biotin is required for normal metabolism.

But biotin deficiency is rare.

Eating eggs can be part of good nutrition.

It does not mean that extra biotin automatically makes hair grow faster.

Easy Ways to Use Eggs

• Boiled eggs
• Eggs with spinach
• Vegetable omelets
• Eggs with whole grain toast

2. Salmon and Trout

Fatty fish are excellent sources of protein.

They also provide omega 3 fats.

Salmon and Trout Can Provide

• Protein
• Vitamin D
• Vitamin B12
• Selenium
• EPA and DHA omega 3 fats

Vitamin D Source

NIH lists fatty fish such as salmon and trout among the best natural food sources of vitamin D.

Omega 3 Fats Are Useful Nutrients

They form part of a healthy dietary pattern.

But eating salmon has not been proven to regrow hair lost from genetic or autoimmune disease.

Other Fish Count Too

Try:

• Sardines
• Mackerel
• Herring
• Tuna

For more fat sources, read 20 Healthy Fats Food.

3. Chicken and Turkey

Chicken and turkey are straightforward sources of high quality protein.

Protein Supports Normal Tissue Formation

Your body uses dietary amino acids to build many proteins.

This includes keratin.

Choose Preparation Based on the Whole Meal

Try:

• Roasted chicken
• Grilled chicken
• Chicken with vegetables
• Turkey with whole grains

You Do Not Need Meat for Healthy Hair

Plant based protein can also meet protein needs when the diet is well planned.

4. Lean Beef

Lean beef provides protein, iron, zinc, vitamin B12, and other nutrients.

Heme Iron

Iron from meat is present in a form that is generally absorbed efficiently.

Iron Deficiency Can Matter

Low iron status can occur for several reasons.

It is especially important to investigate possible deficiency when hair loss occurs with:

• Fatigue
• Heavy menstrual bleeding
• Pregnancy
• Frequent blood donation
• Restricted diets
• Digestive disease

Do Not Eat Large Amounts of Red Meat Just for Hair

Hair health depends on the whole diet.

Iron is also available from plant foods.

5. Lentils

Lentils are useful for people who want protein and iron from plant foods.

Lentils Provide

• Plant protein
• Iron
• Folate
• Fiber
• Magnesium
• Other minerals

Add Vitamin C

Vitamin C can improve absorption of nonheme iron from plant foods.

Combine lentils with:

• Bell peppers
• Tomatoes
• Lemon
• Oranges

Lentils Are Affordable

You do not need expensive superfoods to support good nutrition.

6. Beans and Chickpeas

Beans and chickpeas provide a useful mix of plant protein, iron, zinc, folate, and fiber.

Useful Choices Include

• Black beans
• Kidney beans
• White beans
• Chickpeas
• Pinto beans

Use Them With Whole Grains

Beans with rice, bulgur, or another grain can form a nutritious meal.

Canned Beans Are Fine

Choose lower sodium options when available.

Draining and rinsing can remove some sodium.

7. Plain Greek Yogurt

Greek yogurt can provide a substantial amount of protein in a convenient serving.

It May Also Provide

• Calcium
• Vitamin B12
• Phosphorus
• Other nutrients

Vitamin D Varies

Some yogurt is fortified with vitamin D.

Others are not.

Check the nutrition label.

Choose Plain More Often

Plain yogurt can reduce added sugar compared with many flavored products.

Add Your Own Toppings

Try:

• Berries
• Oats
• Walnuts
• Chia seeds

Read Health Benefits of Yogurt for more detail.

8. Tofu and Other Soy Foods

Tofu is another useful protein choice.

Soy Foods Can Include

• Tofu
• Tempeh
• Edamame
• Fortified soy milk

They Can Provide

• Protein
• Iron
• Zinc
• Healthy fats
• Other nutrients

Fortified Soy Milk Can Add More Nutrients

Some products contain added:

• Calcium
• Vitamin D
• Vitamin B12

Compare labels because products differ.

9. Spinach and Other Leafy Greens

Leafy vegetables can contribute several important nutrients to a varied diet.

Spinach Provides

• Folate
• Iron
• Vitamin C
• Beta carotene
• Other vitamins and minerals

Plant Iron Is Absorbed Differently

Iron from plant foods is called nonheme iron.

Eating vitamin C rich foods with it can improve absorption.

Useful Pairings

Try spinach with:

• Bell peppers
• Tomatoes
• Lemon
• Beans
• Lentils

Spinach Does Not Cure Iron Deficiency

Significant iron deficiency may require medical investigation and treatment.

10. Bell Peppers, Berries and Citrus Fruit

These foods are useful sources of vitamin C.

Vitamin C Helps Absorb Plant Iron

This can make it especially useful with beans, lentils, tofu, and leafy vegetables.

Good Choices Include

• Red bell peppers
• Oranges
• Kiwi
• Strawberries
• Blueberries
• Grapefruit

Vitamin C Has Other Roles

Your body needs vitamin C for normal collagen formation and many other functions.

Fruit Is Better Than a Hair Gummy

A varied diet provides many nutrients together.

A supplement should not automatically replace food.

11. Oysters and Other Seafood

Oysters are particularly rich in zinc.

NIH Lists Oysters as a Major Zinc Source

Other sources include:

• Fish
• Crab
• Lobster
• Meat
• Poultry

Zinc Deficiency Can Cause Hair Loss

NIH notes that zinc deficiency can cause hair loss.

This Does Not Mean More Zinc Gives Everyone More Hair

Once your zinc needs are met, taking excessive amounts does not guarantee better hair growth.

Too Much Zinc Can Be Harmful

Long term excessive zinc supplementation can interfere with copper status and cause other health problems.

12. Nuts

Nuts provide healthy fats, plant protein, vitamin E, minerals, and other nutrients.

Useful Choices Include

• Almonds
• Walnuts
• Pistachios
• Peanuts

Walnuts Provide Plant Omega 3 Fat

They contain ALA, a type of omega 3 fatty acid.

Almonds Provide Vitamin E

Vitamin E is an antioxidant nutrient.

Portions Still Matter

Nuts are nutrient rich but energy dense.

A small portion is enough for many meals or snacks.

13. Seeds

Seeds provide a concentrated mix of healthy fats, minerals, fiber, and some protein.

Useful Seeds Include

• Pumpkin seeds
• Chia seeds
• Ground flax seeds
• Sunflower seeds
• Sesame seeds

Pumpkin Seeds Provide Zinc

They can contribute zinc within a varied plant based diet.

Chia and Flax Provide ALA

This is a plant form of omega 3 fat.

Seeds Are Not Hair Growth Medicine

They support good nutrition.

They cannot reverse follicle damage from scarring alopecia or advanced genetic hair loss.

14. Sweet Potatoes and Carrots

Sweet potatoes and carrots provide beta carotene.

Your Body Can Convert Beta Carotene to Vitamin A

Vitamin A is needed for normal cell function.

Food Sources Are Different From High Dose Supplements

Getting vitamin A from normal foods is not the same as taking large amounts of preformed vitamin A in supplements.

Too Much Vitamin A Can Be Harmful

AAD warns that excessive amounts of some nutrients, including vitamin A, have been linked to hair loss.

Do Not Megadose Vitamin A for Hair

More is not better.

A varied diet is the safer starting point.

Why Is Protein Important for Healthy Hair?

Protein is one of the most important nutrients to consider when overall intake is inadequate.

Hair Contains Keratin

Keratin is a protein.

Very Low Protein Intake Can Affect Hair

AAD states that inadequate protein intake can contribute to hair loss.

Protein Sources Include

• Eggs
• Fish
• Chicken
• Lean meat
• Yogurt
• Beans
• Lentils
• Tofu
• Nuts
• Seeds

You Do Not Need Extreme Protein Intake

Your needs depend on age, body size, activity, health, pregnancy, and other factors.

People with kidney disease may require individual advice.

What Is the Link Between Iron and Hair Loss?

Iron deficiency deserves attention when evaluating hair loss.

Iron Is Needed for Hemoglobin

Hemoglobin helps red blood cells carry oxygen.

People at Higher Risk of Low Iron Include

• People with heavy menstrual bleeding
• Pregnant people
• Frequent blood donors
• People with gastrointestinal disorders
• People who lose blood
• Some people who avoid meat and seafood

Food Sources Include

• Meat
• Seafood
• Poultry
• Beans
• Lentils
• Fortified cereals

Do Not Take Iron Without a Reason

Iron supplements can cause side effects.

Too much iron can be dangerous.

If deficiency is suspected, appropriate testing can help guide treatment.

Does Zinc Support Hair Health?

Your body needs zinc for normal cell growth, protein production, immune function, and wound healing.

Zinc Deficiency Can Cause Hair Loss

NIH includes hair loss among possible signs of zinc deficiency.

Zinc Food Sources Include

• Oysters
• Meat
• Fish
• Poultry
• Beans
• Nuts
• Whole grains
• Eggs
• Dairy products

Do Not Take Large Zinc Doses for Hair

Too much zinc can cause nausea and other problems.

Long term excessive intake can also reduce copper levels.

What About Vitamin D and Hair?

Vitamin D has several important roles in the body.

Researchers have also studied vitamin D status in several forms of hair loss.

Low Vitamin D Does Not Prove It Caused Your Hair Loss

An association is not the same as proof of cause.

Good Food Sources Are Limited

NIH lists fatty fish among the strongest natural food sources.

Other Sources Can Include

• Fortified milk
• Fortified plant milk
• Fortified cereals
• Some fortified yogurt
• Egg yolks
• Ultraviolet exposed mushrooms

Testing and Supplements Should Match Your Needs

Do not assume that taking a large vitamin D dose will regrow hair.

Does Biotin Make Hair Stronger?

Biotin is probably the most marketed hair vitamin.

Biotin Deficiency Can Cause Hair Thinning

This is real.

But Deficiency Is Rare

NIH states that most people get enough biotin from food.

Evidence for Extra Biotin Is Weak in Healthy People

NIH states that there is little scientific evidence supporting biotin supplements for improving hair, skin, or nails in people who are not deficient.

Biotin Is Found in Normal Foods

Sources include:

• Eggs
• Fish
• Meat
• Nuts
• Seeds
• Other foods

High Dose Biotin Can Affect Blood Tests

Large supplemental doses may cause false laboratory results.

This can interfere with some hormone and other important tests.

Tell your healthcare professional about biotin supplements before blood testing.

Do Healthy Fats Matter for Hair?

Your body needs essential fatty acids.

Healthy fats also help you absorb fat-soluble vitamins.

Useful Foods Include

• Salmon
• Sardines
• Walnuts
• Chia seeds
• Flax seeds
• Avocado
• Olive oil

Fat Does Not Directly Moisturize Hair From Inside

Eating more oil does not automatically make dry hair glossy.

Think About Overall Diet Quality

Healthy fat is one part of balanced nutrition.

Can Eating Too Few Calories Cause Hair Loss?

Yes.

This is an important issue in aggressive dieting.

AAD Warning

The American Academy of Dermatology states that eating too few calories every day can cause significant hair loss.

Rapid Weight Loss Can Trigger Shedding

The body may respond to major physical stress by shifting more hairs into the shedding phase.

Do Not Starve Yourself for Faster Weight Loss

A very aggressive diet can affect:

• Protein intake
• Iron intake
• Vitamin and mineral intake
• Overall energy availability

Choose Sustainable Weight Management

Read Healthy Way to Lose Weight if weight management is also one of your goals.

Can Vegetarian and Vegan Diets Support Healthy Hair?

Yes.

A well planned plant based diet can provide adequate nutrition.

Protein Sources Include

• Beans
• Lentils
• Chickpeas
• Tofu
• Tempeh
• Edamame
• Nuts
• Seeds

Iron Needs More Planning

Plant iron is absorbed less efficiently than heme iron.

Pair plant iron foods with vitamin C.

Zinc Also Deserves Attention

Beans, nuts, seeds, whole grains, and soy foods can contribute zinc.

Vitamin B12 Needs Special Attention in Vegan Diets

Vitamin B12 is naturally found mainly in animal foods.

People following vegan diets need reliable fortified foods or appropriate supplementation.

Vitamin D May Also Need Attention

Fortified foods can help.

Individual needs vary.

Should You Take Hair Growth Supplements?

Not automatically.

AAD Recommends Checking for Deficiency First

A blood test may help determine whether you are low in certain nutrients when your history suggests a possible deficiency.

Too Much Can Cause Harm

AAD specifically warns that excess amounts of some nutrients can worsen hair loss.

Biotin Can Distort Laboratory Results

This is an important safety issue.

Iron Can Be Dangerous in Excess

Do not take it simply because your hair is thinning.

Zinc Can Be Harmful in Large Amounts

Long term excess may lead to copper deficiency.

Food First Is a Good Starting Principle

AAD advises healthy adults to try to meet nutrient needs through food unless there is a medical reason for supplementation.

Use the Nutrition and Vitamins Hub before assuming a hair supplement is necessary.
