When experiencing postpartum hair loss, women should enhance their nutrition by consuming more iron-rich foods, such as soybeans, black beans, seafood, spinach, and red beans, all of which contain abundant iron. Iron deficiency after childbirth is also related to the occurrence of anemia. Additionally, consuming plenty of protein-rich foods is essential, particularly since the growth of hair needs the amino acid cysteine. Therefore, it's indispensable to supplement proteins. In everyday life, one can eat chicken, beef, eggs, milk, and soy products, which all are rich in high-quality plant proteins and are excellent choices. Moreover, it’s beneficial to eat a moderate amount of iodine-containing foods, such as kelp and seaweed.
