Food supports hair health, but it does not regrow hair on its own. These guides cover foods rich in nutrients linked to hair health, common nutrition myths, and how to think about supplements. They are informational only and are not medical advice. If you have deficiency symptoms, sudden shedding, or a medical condition, talk to a doctor before changing your diet or taking supplements.

Frequently asked questions
What foods help hair growth?
Protein, iron, zinc, omega-3 fats, vitamin D, and biotin-rich foods all support hair health. A varied diet with eggs, fish, legumes, nuts, seeds, and leafy greens covers most of these. No single food regrows hair on its own.
Do biotin supplements help hair?
Biotin helps mainly when you are deficient, which is uncommon if you eat a varied diet. High-dose biotin can also interfere with some lab tests, so talk to a doctor before taking it.
Can diet cause hair shedding?
Yes. Crash diets, very low protein or calorie intake, and nutrient deficiencies can trigger shedding a few months later. Eating enough, with balanced protein and nutrients, helps prevent diet-related shedding.
