Diet for Hair: Protein, Iron, Vitamin D and Zinc — From Food, Not Gummies

Protein: the raw material

Hair is almost entirely keratin, a protein. When protein intake crashes — crash diets, illness, long fasting without planning — the body cuts hair production early because hair is non-essential. A practical floor for most active men is around 1.2-1.6 g of protein per kg body weight per day; even sedentary men should not sit below roughly 0.8-1 g/kg for months. For a 70 kg man that means roughly 85-110 g a day across meals — dal, curd, milk, eggs, paneer, soya and chicken in normal portions get most men there.

Iron and ferritin

Ferritin — stored iron — is one of the most common hidden causes of increased shedding, and vegetarian men are not immune just because they eat spinach. Plant iron absorbs poorly; pairing iron-rich foods with vitamin C (a squeeze of lemon on dal, amla, citrus with meals) improves absorption several-fold, while tea with meals blocks it. Red meat and eggs provide the easily absorbed form. If a blood test shows low ferritin, your doctor may prescribe iron — self-dosing iron without a test is a bad idea, as excess iron is harmful too.

Vitamin D and zinc

Vitamin D deficiency is widespread in Indian men despite the sunshine — indoor work, covered skin and sunscreen limit production. Low levels are linked with increased shedding. Food sources are few (fatty fish, egg yolk, fortified foods), so a confirmed low level usually needs a doctor-guided supplement course; this is the one hair supplement that frequently is justified in India — after a test. Zinc comes from meat, shellfish, dairy, nuts, seeds and whole grains; genuine zinc deficiency is less common and mega-dosing zinc can push copper levels down.

The test-before-supplement rule

A CBC, ferritin, vitamin D, B12 and TSH panel costs roughly ₹800-1,800 at most Indian labs and answers the diet question properly. Supplement only what is low, at the dose advised, and retest in about 3 months. Blind stacks of five supplements do three harms: they empty your wallet, mega-dose biotin can distort future lab reports, and they delay the real diagnosis when the cause is thyroid or genetics, where no diet will help.

What a hair-friendly day of eating looks like

Breakfast: eggs or sprouted moong with curd. Lunch: dal or rajma/chana, sabzi, roti/rice, lemon squeezed over everything, salad. Snack: a handful of peanuts, roasted chana or pumpkin seeds, or a glass of milk. Dinner: paneer, soya, chicken or fish with vegetables. That ordinary day quietly covers protein, iron, zinc, B12 (from dairy/eggs) and most micronutrients. No exotic seeds, no imported powders — the Indian kitchen was already built for this.
