The only advantage of plucking hair is to make your skin look smooth and delicate (for girls, boys are totally unnecessary). Girls want to be beautiful in summer, it is best to use depilatory cream, but pay attention when buying depilatory cream. It usually grows back after it is taken off. Never shave with a razor. The longer it is, the thicker it is. But plucking has a lot of disadvantages: 1. Hair, as its name implies, is related to sweat discharge. Below the hair follicle are sweat glands and next to them are sebaceous glands. Sweat and grease are discharged to the root of the hair follicle through the catheter, and then discharged to the outside of the skin through the hair surface, so as to achieve the effects of heat dissipation and skin lubrication. Here, the hair plays a role in drainage. Once the hair is artificially damaged, it may lead to poor perspiration and reduce skin heat dissipation. At the same time, oil can not be discharged smoothly, which is easy to cause dry skin. 2, the hair on the skin also plays a role in keeping warm (now degraded) and defending (stimulating sensors). When external stimuli come into contact with hair, you usually feel it, so the group plays an early role. 3, once the hair is pulled out, bacteria may enter the hair follicle through the primary hole, causing folliculitis. A single folliculitis is called furuncle, and many furuncles can lead to metastatic infection. Therefore, it is best not to pluck hair. Usually, the flourishing degree of hair is related to the quantity and proportion of hormone secretion, that is, the ratio of androgen to estrogen. In some monographs, androgens and estrogens are the same. When androgen secretion is excessive, there will be a phenomenon of vigorous body hair. It is for this reason that men have stronger body hair than women.
