Introduction: Aging is a topic that has attracted much attention since ancient times and is avoided, as the years go by, our ** gradually relaxes, pigmentation and wrinkles appear one after another, and hair gradually turns white.
Most people naturally blame the passage of time for these changes, however, some traditional ideas and theories have aroused people's curiosity: is the location of gray hair related to physical ailments?
In ancient times, it was widely believed that gray hair was a manifestation of old age and a natural physiological phenomenon, however, with the development of modern medicine, we have gradually realized that gray hair is not only a physiological phenomenon, but may also indicate some potential problems in the body.
Many people find that the position of white hair growth is generally on the forehead, the back of the head and the temples, so what does the white hair grow on the forehead, temples and the back of the head?
Genetic factors
Heredity is one of the main factors that contribute to gray hair, and if there are members of the family who have gray hair early, then you may be more likely to develop gray hair at an earlier age.
Age factor
As we age, the pigment cells in the hair gradually decrease, leading to the appearance of gray hair, which is usually more common in middle age or old age.
Oxidative stress
Oxidative stress is a process by which free radicals and oxidants damage cells, leading to the oxidation of DNA, proteins, and lipids, which in turn affects hair pigment production.
Nervous stress and mental stress
Long-term exposure to excessive psychological and mental stress may lead to damage to hair follicles, resulting in gray hair.
Diseases and medications
Certain diseases and medications may cause the appearance of gray hair. For example, thyroid problems, vitamin B12 deficiency, autoimmune diseases, etc. may be associated with gray hair.
Certain chemicals
Long-term exposure to certain chemicals, such as hair dyes, dyes, chemicals, etc., may cause damage to the hair, leading to the appearance of gray hair.
Where does the gray hair grow, where does the disease come out?It's a popular folk saying that gray hair can be a warning sign of some kind of health problem.
This claim is not entirely unfounded, according to a 2022 study published in the prestigious journal Geriatrics Research, in which scientists found that about 5% of gray hair cases are associated with some form of disease.
These diseases mainly include metabolic diseases, chronic diseases and malnutrition, metabolic diseases such as diabetes, hyperlipidemia, etc., and their pathological processes will affect blood circulation, resulting in insufficient nutrition of hair follicles, which in turn leads to gray hair.
Chronic diseases such as cardiovascular disease, kidney disease, etc., may also affect the health of the hair, leading to gray hair, while malnutrition, especially vitamin and mineral deficiencies, can also lead to gray hair.
Forehead – disorders of the spleen and stomach
The growth of white hair on the forehead is usually caused by the imbalance of the spleen and stomach, which is mentioned in the "Yellow Emperor's Neijing": "The forehead belongs to Yangming, and Yangming is mainly related to the spleen and stomach. "Therefore, when the body has this symptom, it needs to be taken seriously. The forehead corresponds to the reflex area of the spleen and stomach in traditional Chinese medicine, and when the body has symptoms, we must pay close attention to it, and the long gray hair on the forehead is a reminder that we need to regulate the spleen and stomach as soon as possible.
Spleen and stomach disorder is a common disease, and the usual unreasonable diet, emotional depression and discomfort, so that the spleen and stomach body disorder, dampness and heat obstruction and caused by symptoms, therefore, in daily life, we need to pay attention to the maintenance of the spleen and stomach.

When Kidney Qi is insufficient, hair is also affected, and symptoms such as gray hair, hair loss, and dull hair may occur, and there are many reasons for Kidney Qi deficiency, including congenital deficiency, malnutrition, excessive fatigue, chronic diseases, etc.
These factors can affect the normal function of the kidneys, resulting in a deficiency of kidney qi, in addition, as we age, kidney qi will gradually weaken, which is one of the reasons why elderly people are prone to gray hair.
Sideburns - the liver is hot
White hair growing on the temples may be a common phenomenon, liver fire refers to the excessive fire inside the liver, resulting in a series of uncomfortable symptoms in the body, among them, white hair growing on the temples is one of the typical manifestations of liver fire.

This claim has no scientific basis, it is purely a folk theory, and has not been scientifically verified.
