Is male baldness due to kidney deficiency?

Generally speaking, hair loss is more common in men than in women, especially in middle age. Many people who do mental work have a higher frequency of hair loss. There are several types of hair loss in men, including alopecia areata and premature alopecia. Alopecia areata is a temporary hair loss that occurs suddenly. Sometimes after getting up in the morning, you will find hair loss spots of varying sizes on your hair.

Generally speaking, hair loss is more common in men than in women, and it is more common in those who do mental work than in those who do physical work. Hair loss tends to run in families. Hair loss is related to the body's endocrine function (mainly male hormones), mental and neurological state, genetics, and certain drugs.

There are two main types of hair loss in men: alopecia areata and premature hair loss. Alopecia areata is a temporary hair loss that occurs suddenly. Sometimes after getting up in the morning, you will find bald spots of varying sizes on your head, which is commonly known as "alopecia areata". The onset of alopecia areata is related to neuropsychiatric factors. It may be because high mental tension affects the regulatory function of the nervous system, directly or indirectly damaging the hair follicles and causing hair loss.

Premature hair loss is a permanent type of hair loss. Some men begin to experience post-epidermal hair loss after puberty. The hair then becomes greasy and shiny, and the amount of dandruff gradually increases. Sometimes the hair becomes dry and dull, and often itchy. The hair will fall out if you scratch it with your hands.

Especially on both sides of the forehead, chronic diffuse hair loss will occur. Over time, the hair will become thinner and thinner. If not treated actively, the top of the head will gradually become bald, which is called "baldness". In medicine, it is called male pattern alopecia, also known as "fat alopecia". Because premature hair loss is often accompanied by increased sebum secretion, it can also be called seborrheic alopecia.

Seborrheic alopecia is related to the following three factors:

(1) Male hormones: Modern medicine has confirmed that people with seborrheic alopecia generally have higher levels of male hormones. This is mainly because the male hormones secreted by the testicles enter the blood circulation, reach the scalp and stimulate the hair follicles. If the energy metabolism and protein metabolism of the hair follicles are impaired, hair loss will occur.

(2) Genetic factors: The gene for seborrheic alopecia is dominant in men, and the cause of the disease can be directly passed on from one generation to the next, so seborrheic alopecia is more common in men.

(3) Age: As men age, the incidence of fat alopecia gradually increases. Fat alopecia often occurs in male adolescents between the ages of 17 and 20, with the peak incidence at around 30 years old. As men age, the incidence decreases, but the symptoms worsen and eventually turn into baldness.
