The causes of hair loss are closely related to factors such as hormonal influences, diet, and mental stress.
Iodine can make hair soft and shiny, and prevent it from drying out. It can promote the secretion of thyroxine, and thyroid hormones are deeply related to hair growth. Animal foods contain no iodine, while marine plants such as kelp and wakame are rich in iodine, and these algae also contain large amounts of calcium and iron.
The components of hair contain sulfur-containing amino acids. For example, cystine and methionine. These amino acids are all of the protein type, and they are quite abundant in the proteins found in soybeans, peanuts, sesame seeds, etc. The saying passed down from ancient times that "eating sesame seeds frequently can make 'hair regrow and turn white hair black'" has a scientific basis, and at least such plant-based foods can supply the main nutrients for hair.
Cholesterol secreted from the body and accumulating on the scalp is not only a cause of dandruff, but also a major cause of hair loss and baldness, as it blocks sweat glands and sebaceous glands, weakening the metabolism of the scalp and making hair growth difficult. Excessive mental stress can cause localized alopecia areata, and there are even legends that in severe cases, a person can become completely bald overnight. Bald patients can improve and prevent hair loss through medical treatment and dietary conditioning.
