What food can reasonably do
Hair is produced by some of the most metabolically active cells in the body. Adequate overall nutrition supports that process working normally.
That is the honest claim: support for normal function. These foods support normal nutrition and hair biology. No individual food is proven to make everyone's hair grow faster.
Protein
Provides the amino acid building blocks used in keratin production.
- Eggs
- Fish
- Poultry
- Greek yogurt
- Tofu
- Beans
- Lentils
Iron
Supports oxygen delivery to metabolically active tissue, including the follicle.
- Lean meats
- Beans and lentils
- Fortified cereals and foods
- Leafy greens
Pairing plant iron sources with vitamin C-rich foods can support absorption.
Zinc
Involved in protein synthesis and cell division.
- Shellfish where appropriate
- Meat
- Beans
- Nuts
- Seeds
Vitamin D
Involved in follicle cycling; dietary sources are limited, which is why fortified foods matter.
- Fatty fish
- Egg yolks
- Fortified foods
Vitamin C
Supports collagen formation and helps the body absorb plant-source iron.
- Citrus
- Berries
- Bell peppers
- Broccoli
Dietary fats
Support normal cell membranes and the absorption of fat-soluble vitamins.
- Fatty fish
- Nuts
- Seeds
- Olive oil and other everyday fat sources
Putting it on a plate
- Breakfast — eggs with spinach and wholegrain toast, plus citrus.
- Lunch — lentil and roasted-pepper salad with pumpkin seeds and olive oil.
- Dinner — salmon, brown rice and broccoli.
- Plant-based day — tofu stir-fry with beans, sesame seeds and bell peppers.
