Eggs promote hair growth. They contain omega-3 fatty acids and biotin, both of which help hair grow. However, eating too many egg whites can hinder hair growth by preventing biotin from being absorbed by the body.
Many foods promote hair growth because of the nutrients they contain, such as almonds, which contain biotin just like eggs do. Another good food for hair growth is sunflower seeds, which are rich in vitamin E. Vitamin E helps hair grow by improving blood flow in the scalp. Another nutrient that promotes hair growth is beta carotene, which can be found abundantly in sweet potatoes and carrots.
