What is the reason for men's hair loss?

Nowadays, men always cause great harm to their social life and their health. Many men have symptoms of less hair. At this time, because some patients do not know the cause, there are some difficulties in treatment. Therefore, many patients want to know what is the cause of less hair in men?

a) Glands

① Gonads: Androgens play an important role in stimulating the growth of hair mother cells.

② Adrenal gland: Excessive secretion of male hormones in the adrenal cortex can cause hirsutism in women. However, it is also related to the function of the pituitary gland. If the pituitary gland function degenerates, hair may decrease or fall out.

③Thyroid gland: The normal function of the thyroid gland plays an important role in hair growth. If it is dysfunctional, the hair in the outer 1/3 of the eyebrows will fall out. When the function declines, not only will the color fade to gray, but the hair will also decrease or fall out. The growth and shedding of hair is mainly controlled by the growth period of the hair itself, but also by other factors such as race, endocrine, disease, mental condition, gender, age, season and other factors.

(1) Race: Racial differences are a relatively obvious phenomenon. People of different races not only have different hair colors, but also different amounts and growth patterns of their hair. Baldness is very common among white people, less common among Chinese, and even rarer among Indians. (2) Genetics: In the same family, hair growth patterns are often roughly the same. Male pattern baldness is closely related to genetics.

(3) Endocrine: Male hormones can directly act on the hair follicles, causing male pattern baldness. People who lack male hormone stimulation (such as eunuchs) will not experience this phenomenon. Female hormones have the effect of counteracting male hormones, so women rarely experience baldness before menopause. When thyroid hormone is insufficient, the hair is sparse, and when the adrenal glands are in poor function, the hair decreases. Decreased function of the anterior pituitary gland can lead to complete hair loss.

(4) Mental condition: Tension, fear, and anxiety can significantly increase hair loss. It was reported that a death row inmate lost more than 1,000 hairs a day after being sentenced.

(5) Vitamins: Long-term deficiency of vitamin A can lead to thinning hair; deficiency of vitamin B2 can cause increased sebum secretion and hair loss; deficiency of vitamin B6 can cause abnormal sebum secretion. Oral contraceptives can accelerate metabolism and consume more vitamin B6. Some women may suffer from diffuse hair loss due to this. In addition, vitamin B6 can affect the pigment metabolism process. When it is deficient, the hair can turn gray and grow poorly; deficiency of pantothenic acid (also known as vitamin B3) can cause hair to turn white and grow poorly; inositol belongs to the vitamin B family and can prevent hair loss; deficiency of biotin (also known as vitamin H2) can cause hair loss; para-aminobenzoic acid also belongs to the vitamin B family and can protect hair color and maintain normal hair growth. (6) Trace elements: Some scholars have observed the changes in the trace elements zinc, iron, molybdenum, calcium, lead, magnesium, manganese and selenium in hair and found that the zinc, copper, iron and manganese levels in patients with hair loss were significantly reduced, while the calcium, magnesium and selenium levels were significantly increased. There was no difference in the values ​​of the elements in patients with atypical hair loss. Copper deficiency can affect the absorption and utilization of iron. Poor iron metabolism can cause symptoms such as anemia and mental agitation. The latter can be a triggering factor for alopecia areata. Copper deficiency can also affect the keratinization process of hair, thereby affecting hair growth. Calcium exerts its effect by binding to calcitonin. High calcium concentration may change the immune regulatory function of the central nervous system, thereby leading to hair loss. Excessive selenium can cause hair loss due to autoimmune reactions and increased scalp seborrheic dermatitis.

(7) Disease: Certain systemic diseases, such as febrile diseases, anemia, malnutrition, liver disease and severe chronic wasting diseases, can often lead to thinning hair.

(8) Gender and age: Women's hair grows faster than men's, and young people grow faster than old people, but the difference is not very large. As people age, the number of hair follicles on their heads decreases significantly. According to statistics, the number of hair follicles per square centimeter is 615 for people aged 20 to 30, 485 for people aged 30 to 50, and 435 for people aged 80 to 90.

(9) Other factors: Hair grows slightly faster in summer than in winter because the rise in temperature can promote metabolism and lead to faster hair growth. Hair grows slightly faster during the day than at night. X-rays can control sulfhydryl compounds in the hair follicle matrix, thereby causing temporary hair loss. Certain chemical factors such as iron can affect keratinization and may interfere with cystine's participation in the composition of keratin, thereby affecting hair growth. Ultraviolet rays, drugs, trauma, chronic inflammation, skin diseases, local massage stimulation, etc., also have a certain impact on hair growth and loss.

What is the reason for thin hair in men? Those who may not know it at first should now have a good understanding of it through the above. In this way, we can call for better treatment methods according to the cause of the disease to ensure the smoothness and effectiveness of the treatment. Therefore, the content above is still very necessary for a better and happier life.
