Oils, shampoos, or treatments are not the sole causes of healthy hair growth. The hair follicles are still living cells and are highly dependent on food that is delivered through the bloodstream.
The body will be short of the necessary nutrients, which will eventually lead to hair growth being slow, hair being thin, and increased hair fall.
Therefore, diet is of utmost importance for hair to grow, thicken, and be healthily maintained over a long period.
About the top 10 foods for hair growth, this guide will go into detail, and not only will it tell you how they affect the body, but also why these foods are classified as biotin-rich foods for hair growth, iron-rich foods for hair growth, and the best vegetarian and vegan foods for hair growth, particularly in the Indian diet.
How Nutrition Affects Hair Growth
Hair follicles are distinctly among the cells with the highest metabolic rate in the organism and need a regular supply of the most important nutrients to keep healthy hair growth:
- Keratin and proteins: The keratin that is the basic structure of hair is made of proteins, and thus, protein gives hair strength, thickness, and durability.
- Vitamins like biotin, vitamin A, C, D, and E: These vitamins are involved in the process of cell death and renewal, collagen formation, scalp health, and at the same time, they protect the follicles from the damage caused by oxidative stress.
- Minerals like iron, zinc, and selenium: The minerals help transport oxygen to hair roots, balance the activity of oil glands, and sustain the cycles of follicle repair and growth.
- Healthy fats for scalp hydration and follicle strength: Good fats keep the scalp moist, soothe inflammation, and make hair follicles strong and flexible.
A deficiency in essential nutrients in the diet causes the hair follicles to prematurely enter the resting phase, which then results in hair loss, increased hair fall, and shedding becoming more frequent over time.
1. Eggs – One of the Best Biotin Foods for Hair Growth
Eggs are one of the best sources of biotin and among the most effective foods for hair growth. Biotin has a direct impact on the production of keratin, the structural protein that forms hair.
Key nutrients in eggs
- Biotin (Vitamin B7)
- High-quality protein
- Zinc
- Selenium
How eggs help hair growth
Egg protein gives rise to amino acids, which are the building blocks of keratin, and biotin is a hair root and thickness enhancer. Eggs make the scalp healthy and reduce hair breakage, too.
Eggs are a great source of nutrients that can help with brittle hair, slow hair growth, and excessive shedding caused by nutritional deficiency.
2. Spinach – Iron-Rich Food for Hair Growth
Spinach is considered one of the major sources of iron among foods, contributing to hair growth, especially in cases of hair loss due to a lack of iron in the body.
Key nutrients in spinach
- Iron
- Vitamin A
- Vitamin C
- Folate
How spinach supports hair growth
One of the major functions of iron is to enable red blood cells to transport oxygen to the hair roots. If there is no oxygen, the follicles will die and stop making strong hair.
Spinach’s vitamin C will enhance iron absorption, while vitamin A will create scalp oil that will keep hair hydrated.
In addition to all this, spinach is readily available and is the favorite vegetarian food for growing and thickening hair in Indian diets.
3. Almonds – Nutrient-Dense Food for Hair Growth and Thickness
Almonds are one of the top foods for hair growth and thickness. Besides that, they contain good fats and vitamin E.
Key nutrients in almonds
- Vitamin E
- Biotin
- Magnesium
- Omega-9 fatty acids
How almonds work
Vitamin E improves blood circulation to the scalp and reduces oxidative stress, which can damage hair follicles. Healthy fats nourish the scalp and reduce dryness, improving hair strength and shine.
Regular almond consumption supports thicker hair and reduces hair breakage.
4. Lentils (Dal) – Best Vegetarian Food for Hair Growth
In the case of vegetarian diets, lentils are still ranked high in the list of the best foods that promote hair growth, particularly for those who do not consume meat or other animal protein.
Key nutrients in lentils
- Plant-based protein
- Iron
- Zinc
- Biotin
How lentils promote hair growth
Protein is critical for making the hair shaft, whereas iron has a strengthening effect on the follicles.
Zinc also plays a vital role by limiting the production of oil around the hair follicles and thus preventing the occurrence of scalp problems that can impede hair growth.
In India, lentils are a common food item and are excellent for thickening hair.
5. Sweet Potatoes – Vitamin A Powerhouse for Hair Growth
The growth of hair is enhanced by sweet potatoes since they are able to positively affect both the scalp and the hair follicle.
Key nutrients
- Beta-carotene (converted to vitamin A)
- Fiber
- Antioxidants
How sweet potatoes help
Vitamin A promotes sebum secretion, thus keeping the scalp hydrated and conditioned naturally. When the scalp is healthy, hair follicles stay strong and produce thicker strands of hair.
In India, sweet potatoes are proving to be a safe and effective food for hair growth, especially for people with dry scalp and dull hair.
6. Seeds (Flax, Chia, Pumpkin) – Vegan Foods for Hair Growth
Seeds are extremely recommended vegan foods for hair growth because of their fatty acids and mineral content.
Key nutrients
- Omega-3 fatty acids
- Zinc
- Selenium
- Protein
How seeds support hair health
Omega-3 fatty acids have anti-inflammatory properties on the scalp and thus increase the elasticity of the hair follicles.
Zinc also helps with the repair of damaged hair tissue and takes part in the support of hair growth cycles.
Vegans who are prone to hair thinning due to a lack of fats or minerals can rely on seeds as a source of nutrients.
7. Greek Yogurt – Protein and Probiotic Support for Hair Growth
Greek yogurt is a top-notch provider of protein and good microbes that help to the body digest and absorb nutrients.
Key nutrients
- Protein
- Vitamin B5 (pantothenic acid)
- Calcium
How yogurt helps hair growth
The hair strands are made stronger with the help of proteins, and vitamin B5 promotes circulation in the scalp.
Probiotics play a role in better gut health, which in turn helps to get nutrients that are necessary for hair growth absorbed.
For those who do not eat meat, yogurt is one of the best natural ways to increase hair thickness.
8. Carrots – Scalp Health and Hair Growth Booster
Carrots are one of the key contributors to a healthy hair growth process, and they help scalp function.
Key nutrients
- Beta-carotene
- Vitamin A
- Antioxidants
How carrots help
Vitamin A makes the scalp moist and helps the hair follicles to grow with healthy cells. A well-nourished scalp not only increases the hair growth rate but also decreases hair fall.
Carrots are economical and are found in abundance. So, they are a feasible food for hair growth in India.
9. Beans and Chickpeas – Biotin and Iron for Strong Hair
Beans and chickpeas, besides being the main vegan sources of biotin, also contribute to the daily iron requirement.
Key nutrients
- Biotin
- Iron
- Protein
- Zinc
How beans promote hair growth
They enhance keratin structure and make the roots of the hair stronger. Iron aids the transport of oxygen to the hair, while biotin does the other way around, and that is making the hair strand stronger and thicker.
Chickpeas are of great help for those suffering from hair loss due to a lack of nutrients, particularly.
10. Avocado – Healthy Fats for Hair Growth and Shine
Avocado is an amazing natural food that can enhance the texture of the hair and accelerate its growth.
Key nutrients
- Vitamin E
- Healthy monounsaturated fats
- Vitamin B complex
How avocado supports hair growth
Diets of healthy fats revitalize the hair roots and increase moisture content on the scalp. Working together, Vitamin E scours the hair roots and helps the strands withstand the damage inflicted by the free radicals, therefore, maintaining their strength and brilliance.
Avocado is a great food component to go along with a balanced diet for hair growth.

How Long Does It Take to See Results from Hair Growth Foods?
The process of hair growth, which is a gradual and ongoing biological phenomenon, demands a lot of patience and perseverance to see the final results.
The hair bulbs, for example, will take their time to respond to the changes in nutrition.
Over a long time, little by little, one may see the first signs of improvement if he or she eats consistently nutrient-rich foods that support the health of his or her hair.
- Reduced hair fall: In many cases, it is possible to notice a fall in one’s daily hair loss up to 6–8 weeks as the nutritional lack starts to be rectified and the hair follicles become more stable.
- Improved hair texture: The hair will probably be felt to be healthier, smoother, and less breakable within 2–3 months as a result of better keratin synthesis and scalp feeding.
- Visible hair regrowth: Generally, within 3–6 months, the patient might observe new hair growth or even the existence of an area’s increased hair density, given that the patient’s overall health, age, and nutritional status are all factors considered in this instance.
Patience and perseverance are the keys. Taking a steady supply of nutrients is the way to go for the rejuvenation of the hair roots and the maintenance of the growth cycles in the long term.
Common Mistakes That Block Hair Growth Despite a Good Diet
- Severe calorie restriction: Very low-calorie diets lead to the withdrawal of energy required for active hair growth of the hair follicles, thereby causing hair to fall due to the shedding phase.
- Skipping protein: Hair is mainly composed of keratin (a protein), and insufficient protein intake will weaken the hair, cause slow growth, and reduce the thickness of the hair.
- Excessive junk food: The diet containing high sugar, refined carbohydrates, and trans fats causes inflammation due to nutrient imbalance, and this hurts the health of the scalp and hair roots.
- Chronic stress: Long-term stress raises the level of cortisol, which disturbs the hair growth cycle and leads to the occurrence of stress-related hair loss conditions.
- Poor sleep: Sleep deprivation leads to hormonal imbalance, and tissue repair is compromised, thus lowering the body’s ability to produce healthy hair.
It is a must to take special consideration of these critical factors for the best foods for hair growth to work effectively.
