Hi Kvs,
here are some vegetarian food items which will help you achieve this goal.
Oats: Not only do oats provide sustained energy levels, they also assist in maintaining the natural hair color by aiding in the creation of melatin and can help prevent hair loss. Oats contain important minerals for hair growth such as potassium, phosphorus and magnesium, not to mention iron. It seems oats are an all round super food for hair.
Dried fruit and nuts: Packed with iron, sulphur and biotin, dried fruit and nuts (and almonds in particular) are a great source of vitamin E which enhances blood circulation on the scalp, and inositol which maintains healthy hair follicles. Brazil nuts are one of nature's best sources of selenium, an important mineral for the health of your scalp. Walnuts are also a great source of zinc, as are cashews, and almonds. A zinc deficiency can lead to hair shedding.
Bean Sprouts: Bean sprouts contain an important nutrient for hair health known as silica and a must on your shopping list for foods that prevent hair loss. The body uses silica to help it absorb vitamins and minerals so even if you're eating plenty of vitamins but not consuming silica, they might not be helping much. Hair grows from follicles within the skin at the base of the hair root and need nutrients to form new cells and generate healthy hair growth. Silica can also be found in the skin oc cucumbers, red peppers and green peppers.
Dark Green Vegetables: Spinach (palak) and broccoli are an excellent source of vitamin A and vitamin C, which your body needs to produce sebum. Sebum is an oily substance, secreted by your hair follicles and is the body's natural hair conditioner. Dark green vegetables also provide iron and calcium.
Fruits: Melons, berries, bananas, oranges, apples and many other fruits can supply your body with the proper vitamins to reduce hair loss.
Turmeric (haldi) and cumin (jeera): Contrary to popular belief that spices are bad for health, Spices like turmeric and cumin are good hair foods that boost hair growth.
Water: Consuming at least eight glasses of water per day will help transport the needed nutrients to your hair and help keep your hair strands hydrated and strong.
