Let’s be real for a second. We all want thicker, longer, shinier hair. But somewhere between hair spa appointments and expensive shampoos, most of us forget one simple truth, what you eat shows on your scalp.
No, we’re not saying you need to follow some celebrity’s diet plan or start counting chia seeds at 7 AM. But if you really want to grow better hair, you have to start from the inside. Literally.
This guide is your no-nonsense, practical answer to: What should I eat if I want healthy, happy hair?
We’ll also tell you which top foods for hair growth are easiest to find, especially in Indian kitchens. Ready? Let’s go.
Why Food Matters More Than Fancy Hair Products
Hair is made of protein. It grows from tiny hair follicles that need vitamins, minerals, oxygen, and hydration to do their job well. If your body doesn’t get enough of these through food, it shows up as:
- Hair fall
- Thinning hair
- Dullness
- Slow regrowth
- Premature greying
You may be oiling your hair every weekend and using all kinds of serums. But if you’re skipping your meals or surviving on maggi and chai, your hair won’t get what it needs.
Which Nutrients Are Needed for Hair Growth and Thickness?
To keep it simple, these are the heroes of your hair growth journey:
1. Protein
Hair is 95% keratin, a type of protein. Without enough protein, your strands go weak and fall.
2. Biotin (Vitamin B7)
Biotin is the secret behind faster, healthier growth. If your hair is thinning or not growing past a certain length, low biotin might be the reason.
3. Iron
Iron helps carry oxygen to your scalp. Less iron means weak roots, and yes, that means more hair on your comb.
4. Omega-3 Fatty Acids
These healthy fats make sure your scalp stays hydrated and your hair stays glossy.
5. Vitamin A
It helps produce natural scalp oils. But too much can also cause hair fall. So balance is key.
6. Vitamin C
Vitamin C is great for iron absorption and also boosts collagen. Think stronger strands and fewer split ends.
7. Vitamin D
Helps in creating new hair follicles. Also linked to reducing hair loss.
8. Zinc
Prevents dandruff, strengthens follicles, and supports overall scalp health.
Now that we’ve understood the science a little bit, let’s jump into the best foods for hair growth and thickness you can actually eat every day.
Top 13 Foods That Promote Hair Growth
These aren’t some rare superfoods flown in from overseas. You’ll find most of them in your local kirana store, fridge, or Sunday sabzi bazaar.
1. Eggs – For Biotin and Protein
If there’s one food your hair loves more than anything else, it’s eggs. Full of biotin and protein, eggs literally feed your strands from the inside.
How to eat: Boiled, scrambled, omelette, or sunny side up. Just don’t skip the yolk, it’s where the biotin hides.
2. Spinach – The Iron King
Iron deficiency is one of the biggest reasons for hair fall in Indian women. Spinach is rich in iron, vitamin A, and C, all of which help keep your scalp nourished.
How to eat: In dal, smoothies, palak paneer, or even stuffed parathas.

Fatty fish are packed with Omega-3 fatty acids that keep your scalp moisturised and fight inflammation.
How to eat: Grilled, baked, or in a Bengali-style mustard curry.
4. Sweet Potatoes – For That Natural Shine

Seeds are one of the most underrated natural ingredients for hair growth. They pack in vitamin E, selenium, and zinc.

9. Oysters – Zinc Superstars
Zinc is key for healthy hair follicles. Just one oyster can give you your entire daily zinc requirement.
How to eat: Grilled with lemon or added to seafood biryani.
