Chen Hsin Hung, a TCM doctor at Joyful HAN Chinese Medicine Clinic in Taiwan, posted on his Facebook page to his followers that foods with the following characteristics are not good for healthy hair growth. Those foods that are extremely spicy and salty, high in sugar, high in fat, processed and highly refined, and with excessive alcohol and caffeine fall into this category.
Severely spicy or very salty ingredients
i) Excessively spicy ingredients: TCM attributes that a moderate amount of spicy food intake can help improve blood circulation. However, excessive intake of spicy flavors will cause sweating and excessive sweating will cause loss of body fluid. Excessive loss of body moisture will cause an oily scalp, leading to the blockage of hair follicles and pores, which is not conducive to hair growth.
ii) Excessive Salty Ingredients: TCM believes that salt can enter the kidneys, and an appropriate amount of salt can help replenish trace minerals. However, excessive consumption can put too much strain on the body and can cause blood pressure changes, and it can even cause abnormal circulation problems resulting in insufficient blood flow to the scalp.
Chen pointed out that when blood circulation to the scalp deteriorates, the nourishment of the scalp will decrease and the hair will gradually become chlorotic and slender. That will accelerate the hair follicles to enter the telogen (complete rest) phase and eventually fall off.
High sugar content
Chinese medicine believes that sugar can enter the spleen, and a moderate amount of it can help activate the spleen and improve stomach function.
Sugary substances are one of the main energy sources for metabolism for human cell growth, but too much sugar will activate the action of insulin in the blood and trigger a series of aerobic reactions, which destroy the microorganisms and coenzymes in the blood. are consumed. body. Such added activities involve many oxidation processes, resulting in more multi-oxidation products, such as oxy radicals and acidic species.
Chen said that a diet containing too much sugar will cause a deficiency of trace elements in the short term, resulting in inflammation, excessive sebum secretion, and so on, all of which are unfavorable conditions for the scalp and hair growth, hindering the absorption of nutrients by the hair, and in severe cases, the hair follicles will enter the telogen phase, causing hair loss.
Food that is too tasty probably contains a lot of fat and sugar. Chen reminded us that high-fat and high-sugar foods can both cause an oily scalp and, in severe cases, block hair follicles, cause inflammation and trigger skin diseases such as dandruff, eczema or psoriasis. High-fat foods can also cause increased testosterone in the body, resulting in an increase in dihydrotestosterone, which will worsen androgenetic baldness.
Processed and highly refined foods
Processed foods contain many additives, such as preservatives, artificial colors, artificial sweeteners, and so on. These substances can cause the body to trigger an inflammatory response and in turn cause damage to the body. To make it taste better, processed foods also contain excessive amounts of spices such as salt, sugar and oil, so be warned and don’t consume too much.
Smoking too much, excessive alcohol and caffeine
Smoking has been shown to be associated with many chronic diseases, including cardiovascular disease, the three high blood pressure (high blood pressure, high blood lipids, high cholesterol), and lung disease. Smoking causes poor blood circulation in the scalp and the formation of a high oxygen deprivation environment, which results in insufficient blood flow to the hair and the creation of a superoxide environment, leading to hair loss.
Chen stressed that until now, scientists have no solid evidence that alcohol or caffeinated drinks can directly cause hair loss. However, excessive consumption of alcohol and caffeine from coffee or strong tea will put extra pressure on the endocrine system in the body and cause the sympathetic nervous system (SNS) to be in a continuous state of excitement for a prolonged period of time, which is not conducive to hair growth .
