Is not just what you put on your hair that counts, it's what you ingest as well. Good nutrition fertilises hair, although sometimes nutrients don't reach hair. This is why it is so advisable to apply external aid as well. If you pretend to prevent hair loss, to strength hair roots, to increase scalp circulation and endure follicle life, here is a list of nutrients your hair needs and the food where you could find them:
Vitamin A & beta-carotene: apricots, carrots, cod liver oil, milk, dark green leafy vegetables and sweet potatoes.
Vitamin B: oily fish, tofu, eggs, wholegrain, tomatoes, shitake, dairy products, carrots, shrimps, clams, liver, spirulina, peanuts.
Biotin: Swiss chard, bananas, carrots, walnuts, eggs, dairy, cauliflower, strawberries.
Collagen: gelatine, mushrooms, dark leafy veggies.
