Eating chickpeas basically kills two birds with one stone. You can get both zinc and the vitamin B-6 you need for healthy hair from chickpeas. Zinc has an important part in building hair protein.
Zinc also works together with Vitamin A. Missing one of those two causes you to have dandruff that could contribute to hair loss. Non Vegans can eat roast beef instead and get all of the same benefits and protein as well.
2. Roast beef
Roast beef is another source of Vitamin B-6 and Zinc. It's also a good source of protein. Vegans might consider taking Soy beans instead for protein and chickpeas for vitamin B6 and Zinc.
3. Soy beans
Soy is a great source of protein for vegans. It also contains a substantial amount of Iron and Vitamin E. Iron is an important part of hemoglobin production. Hemoglobin is responsible for getting oxygen to the tissues of the body. Without it your hair won't grow.
Vitamin E also helps with the absorption of oxygen and increasing blood circulation to the scalp.
Almonds are good sources of vegetarian protein, Iron and Vitamin E. They also help to lower cholesterol helping you avoid having to take cholesterol lowering drugs in the future. Some cholesterol lowering drugs actually cause hair loss.
5. Whole wheat
Whole wheat is a good source of Silica and Iron. Silica is very important because it helps with the absorption of many other vitamins and minerals. It's usually not found in abundance in western diets and in many cases it could be one of the main causes of hair loss.
6. cow's milk
Cow's milk has absorbable Iodine. It's impossible to overdose on Iodine from food sources unlike Iodized salt.
Oats are a good source of easily absorbable Iron as well. It's also a good source of Potassium, phosphorus and magnesium.
Oranges (or orange juice) are a good source of Vitamin C. Vitamin C helps make meat and soy sources of Iron more absorbable. Vitamin C is a big part of the development of collagen which is necessary for hair growth.
Fish is a good source of Vitamin A, Vitamin B-6, Protein and essential fatty acids (efa's). EFA's play a major role in maintaining healthy nails, hair and skin.
