Your hair needs vitamin A to stay moisturized and grow. Good sources include sweet potatoes, carrots, spinach, kale and some animal foods.
B-vitamins help carry oxygen and nutrients to your scalp, which aids in hair growth. Whole grains, meat, seafood and dark, leafy greens are all good sources of B-vitamins.
Vitamin C is needed to make collagen and can help prevent hair from aging. Good sources include peppers, citrus fruits and strawberries.

Vitamin E helps prevent oxidative stress and boost hair growth. Good dietary sources include sunflower seeds, almonds, spinach and avocados.
Iron deficiency is a major cause of hair loss, especially in women. The best sources of iron include clams, oysters, eggs, red meat, spinach and lentils.
The mineral zinc can improve hair growth in people who are deficient in it. Good sources include oysters, beef and pumpkin seeds.
