Healthy Food For Hair Growth: What To Eat, Drink, & Avoid

Your hair might feel dull and dry even after spending thousands on hair care products. What many people miss is that the most powerful ingredient for healthy hair is the food on your plate. A good diet plays a greater role than any hair treatment.

You need to choose healthy food with essential nutrients every day for healthy hair growth. A lack of nutrients and hydration reflects in dry and damaged hair.

In this blog, you will find everything about healthy food for hair growth, what to drink for healthy hair, and how your calorie intake affects hair health. We will also discuss essential food supplements, foods to avoid, and special considerations for women.

Connection Between Diet And Hair Growth

Your hair grows from a tube-like structure called a hair follicle. It is made from a key protein called “Keratin”. Including a good source of protein in your diet, like meat, chicken, lentils, and eggs, can help you fulfil your protein requirements. 

However, to achieve healthy and shiny hair, you need more than just protein, a balanced meal with all the right amounts of nutrients is essential.

How Nutrients Fuel Hair Follicles?

Vital nutrients play a crucial role in the growth and development of hair follicles. The hair follicle has three key components that require nutrition:

1. Hair Shaft: The visible part of a hair strand.
2. Hair Root: The part located beneath the skin.
3. Surrounding Tissue: The supportive tissue around the follicle.

 Some of the most important nutrients that fuel hair follicles include:

• Protein: Important to build hair structure.
• Iron: It is essential for carrying oxygen to the hair follicles.
• Biotin: It is essential for the growth of the hair shaft.
• Omega-3 Fatty Acids: Reduce inflammation around hair follicles.
• Vitamins: Many vitamins prevent hair from environmental damage.

A diet that lacks nutrition and has calorie restrictions can lead to hair loss in just a few months.

Calorie Intake for Hair Growth Based on BMI

Your daily calorie needs primarily affect hair health. You can calculate your calorie intake through body mass index (BMI). The Body Mass Index (BMI) formula is:

BMI = Weight (kg) / Height (m)² 

• Weight: Measured in kilograms (kg)
• Height: Measured in meters (m)

BMI Category	Activity Level	Daily Calories	Hair Loss Risk
Underweight (<18.5)	Low	1,800-2,000	Very High
Normal (18.5-24.9)	Moderate	2,000-2,200	Moderate
Overweight (25-29.5)	Low/Moderate	1,800-2,100	Low
Obese (over 30)	Sedentary	1,600-2,000	Low

Your diet must never lack important nutrients. To promote healthy hair growth, prepare a meal plan that includes all the key sources to fulfill your vitamin and mineral intake. Because your hair is as important as your overall health goals.

Foods You Need For Proper Hair Growth And Thickness

You can achieve healthy hair with yummy food options of your choice. Mix and match them to create recipes you love:

1. Eggs: The Complete Hair Food

Eggs contain biotin, a high quality protein for hair. Biotin strengthens the hair strand and prevents hair breakage. One egg provides you with 10 micrograms of biotin, which is one-third of your daily needs.

Egg yolk also has a small amount of vitamin D, which is rare to find in other food sources. You need a sufficient amount of vitamin D for hair growth. Eat at least one egg a day.

2. Salmon: Omega-3 Powerhouse

If you like grilled fish, salmon and other fatty fish are rich in omega-3 fatty acids, an important nutrient for nourishment and hair strength.

Omega-3 fatty acids make the fat layer around the hair follicle thick, enhancing natural hair shine.

3. Greek Yogurt: Scalp Circulation Booster

Your hair also needs good circulation for nutrition; a bowl of Greek yogurt will do that for you. It also contains 20.6 grams of protein, which is the key constituent of keratin in hair follicles.

4. Lentils: Iron-Rich Plant Protein

Lentils have a good quantity of iron and plant-based protein. Protein helps in building the structure of hair follicles while iron helps in the absorption of oxygen for hair cells.

You can enjoy lentils every day by adding them to soups and curries. 

5. Spinach: Double Nutrient Boost

Spinach is from the green vegetable family. It contains iron and vitamin C and works as a double nutrient booster for your hair. Vitamin C helps your body to absorb more oxygen, and iron helps in delivering it to the hair roots. This combination makes your hair strong and healthy.

6.  Avocados: Healthy Fat Source

Fat is not always bad for your body; you need good fat to nourish your hair and add natural shine to it. Avocados are a great source of healthy fat. Fat also helps in the absorption of other major nutrients in the body.

What Fruits Are Best For Hair Growth?

Fruits consist of vitamins and antioxidants. You can take one fruit daily and fulfil your nutrient needs.

Even mild dehydration can affect scalp health and lead to dry hair.

Foods That Cause Hair Loss And Their Alternatives

Some foods can harm hair growth if you eat them in high quantities. You can avoid their daily consumption and replace them with nutrient-dense food products. They include:

• Sugar: Causes inflammation → Choose berries instead.
• Fried Foods: Clog follicles → Switch to nuts or seeds.
• Alcohol: Dehydrates scalp → Drink herbal tea.
• High-Mercury Fish: – Disrupts hormones → Choose salmon.
• Processed Foods: Lack nutrients → Eat whole foods.

What To Eat To Stop Hair Fall Immediately

If you have severe hair fall and want it to stop immediately, focus on nutrient rich food, like protein, calcium, and vitamins. You can also add fruits to your daily routine as they are rich in vitamins and delay aging.

Drink a good amount of water; increase your intake to eight to twelve glasses of water daily. Though it’s hard to avoid packaged and oil foods for some time, your hair will thank you and will start growing in a few weeks.

Which Diet Is Best For Hair Growth For Females?
