脱发原因（Causes of hair loss） Causes of hair loss 1) the main factors: hair follicle specific protein, androgen receptor activity and human male hormone combination, nutrient absorption barriers hinder the formation of hair follicle, the normal physiological cycle leads to serious disturbance of hair. Resulting in an obvious shortening of the growth phase of the hair and an extension of the resting period, resulting in alopecia (alopecia). Other factors: excessive secretion of sebum, hair follicle microcirculation disorder, protein synthesis, invasion and infection of bacteria and fungi, and the effects of human dandruff increase the internal and external environment, will increase the incidence rate of androgenic alopecia. Cause： A. excessive secretion of pomade B. smoking, drinking, eating greasy, spicy and so on C. insomnia, stay up late, excessive mental pressure D. work environment factors (radiation, pollution, etc.) E. family history (inheritance, etc) One: genetic factors In general, male hair loss does not occur in groups that do not carry baldness. This genetic gene is inherited from one of the parents. Although there is no exact textual research, according to some data, it is more likely to obtain such genetic genes from the maternal side. The genetic gene that causes baldness is the dominant gene, and in a pair of sex chromosomes, as long as one has this trait, baldness may occur. Baldness genes are not the same in their offspring carriers. People with a bald genetic gene may not all have baldness. Because in addition to genetic factors, there are many factors at work. For example, hormone secretion, age, a variety of mental stress and other factors also play an important role in the development of baldness. Therefore, even if the older relatives of the family have severe baldness, their offspring may not all be bald. Baldness genes also have genetic records. But there is one thing to be sure that food therapy such as diet and vitamin intake must not increas
