First of all, we must grasp the strength of combing our hair. To dredge the meridians of the whole body, you must comb it a little hard until the scalp is slightly hot, so as to mobilize the yang of the human body. Comb stimulates scalp and acupoints, making scalp slightly numb, and you will feel relaxed and comfortable.

Second: you must comb from front to back, and you must comb backwards, from forehead to neck, from light to heavy, from slow to fast, with your eyes closed and your mind free of distractions, and concentrate on combing.

This method of combing hair two or three times a day can relieve Alzheimer's disease, arteriosclerosis and migraine. It should be noted that it takes a long time to comb the hair to achieve the purpose of health preservation.
