Hair combing is an integral part of dressing up, and correct hair combing can beautify the appearance, protect the hair, and protect the brain. The head is the "head of all yang", and the twelve channels and eight channels of the human body also converge here. There are dozens of head acupuncture points, accounting for about 1/4 of the total body acupuncture points, and more than 10 specific stimulation areas, so hair combing has the effect of health care. In the process of combing hair, the stimulation of "Baihui", "Sishencong", "Shangxing" and other acupoints can increase the blood flow at the root of hair, enhance the activity of melanocytes, and increase the number of melanocytes in hair balls, so that the "nutrition" of black hair can be replenished.
