Does anyone know the operating procedures in the whole process of SPA shampoo and massage?

Massage refers to combing the hair: the fingers of both hands are slightly bent, and the fingertips are pushed from the front hairline to the back hairline through the top of the head. Repeat the operation for 20 ~ 40 times. Pressing the scalp: the fingers of both hands are naturally opened, starting from the forehead, pressing the scalp along the middle of the head to the hairline behind the pillow, and then pressing the scalp on both sides of the top of the head until the whole head. When pressing, the scalp feels swollen, and each time it is pressed for 2 to 3 minutes. Hair pulling: Hold the hair with both hands, and gently pull it upward until the hair is completely pulled 1 time, lasting for 2 ~ 3 minutes. Dry-cleaning hair: Rub the hair of the whole head with two fingers, such as washing hair, for about 2 ~ 3 minutes. Slap the scalp: put your fingers together and gently pat the scalp of the whole head 1 ~ 2 minutes. The above massage methods should be done every morning and evening 1 time. Long-term adherence can prevent white hair, alopecia, dry hair and yellowing.
