To put it simply, the shape of the hair follicle cells determines the straightness of the hair.

1.Hormone secretion.

If you feel that your leg hair is not particularly much, or the leg hair on the woman's legs is relatively dense, then it means that the hormone secretion in our body has undergone some abnormal changes, and if the woman's hair is more vigorous, then it means that the male hormone secretion in his body is also relatively high, in this case, it may have dysmenorrhea and irregular menstruation or infertility, in addition to these, women may also suffer from polycystic ovary syndrome, If there is such a situation, there may also be some problems with more hair, if the man's legs do not have leg hair, then it means that the secretion of estrogen in the body is relatively small, but if other indicators are normal, then it may not affect our health, so don't worry too much.

In fact, for the hair on our body, it also has a lot to do with genes, if your parents' magic is more vigorous, then the children born may also be more vigorous, don't worry too much about this situation, this is also a normal physiological phenomenon, and some people may feel that if the hair is more vigorous, it may affect our beauty.

Although hair has a lot to do with the secretion of hormones, it does not mean that less hair is a manifestation of kidney deficiency, this statement is completely untenable, and there is no scientific basis, so for those men with less hair, don't put too much pressure on yourself, and if the body's indicators are relatively normal, even if your body hair is less, then it will not have much impact on your health.
