The liver, as an important organ of the human body, is responsible for many important physiological functions, such as the breakdown and metabolism of proteins, fats, sugars, and detoxification.
However, since the liver does not have pain nerves, it is often difficult for us to perceive it directly when it is wrong.
Some subtle changes in the body may give us clues. In particular, some of the symptoms of the head may be that the liver is sending us a "distress" signal.
The scalp is prone to oiliness.
The liver is responsible for fat metabolism. When liver function is impaired, fat metabolism may be affected, resulting in an oily scalp. In addition, liver problems may also affect hormone balance, leading to increased sebum production. Therefore, if the scalp is prone to oiliness, it may be the liver that is warning us.
Premature gray hair. 
The liver is also responsible for the metabolism and transport of nutrients. When liver function is impaired, the metabolism and delivery of nutrients may be affected, resulting in a lack of nutrients in the hair and a predisposition to premature gray hair. Therefore, if gray hair appears prematurely, it may be the liver that is sending us a signal.
The complexion is black and yellow. If the liver has the problem of cirrhosis, the endocrine function of the human body will be disordered, resulting in pigment deposition in **, resulting in a dark complexion, dull, and no luster, as if you have not washed your face for many days, which is called "liver disease face".
Some patients have a dark and yellow complexion, and the most obvious place is around the eyes, which will form a large dark circle, and the spirit is very poor.
There are also patients with liver disease who have a liver disease and have "spider angiomas" on the face and nose, which is a lesion with a red, protruding center and many small blood vessels scattered around the center like spider's feet.
The reason for the formation of spider nevi is that when the liver is cirrhosis, the estrogen in the human body cannot be fully inactivated, resulting in the dilatation of small blood vessels in the human body, which is revealed on the **, forming this special form of nevus.
Red nose. 
When there is a lesion in the liver, the liver's ability to inactivate estrogen decreases, which will make the estrogen in the body rise rapidly, and when too much estrogen stimulates the capillaries in the nose, the nose is prone to redness.
In short, some of the symptoms in the head may be the liver is warning us. In order to protect our liver, in addition to paying attention to abnormal changes in the body, we should also develop healthy lifestyle habits.
First, get enough sleep, as the liver repairs itself at night. Secondly, eat a balanced diet and avoid excessively oily and spicy foods to reduce the burden on the liver. In addition, maintaining proper exercise and a good mindset also contributes to the health of the liver. At the same time, regular liver function tests are also an important means to prevent liver problems. Let's take care of our liver and keep our bodies healthy!
