Tibetan medicine mainly looks at the appearance and withering of hair, whether the roots are in harmony with the three factors (dragon, red grass, bacon) in the body. When the blood is abundant, the hair becomes moist, and when the blood is weak, the hair becomes withered. According to the pathogenesis, hair loss and white hair can be classified into three types: blood heat (caused by the invasion of red hot pathogens into the blood), blood deficiency (caused by insufficient blood and bacon), and blood dryness (caused by excessive dragon flow and loss of blood lubrication). Everyone's life cycle and breathing rhythm are different, so in the same environment, some people's hair falls and turns white, while others are unharmed.

So, in the eyes of Tibetan medicine, the three causes and blood related lesions in the human body are directly written on the hair. The scalp is the soil where hair takes root, and if the meridians are not smooth, the hair will not grow.

When there is an imbalance of the three factors and when the red bar is on the rise, the body's functions become hot and the blood generates heat. The heat type belongs to Chiba, which rushes up the upper meridians (black veins) to the various acupoints on the head, steams and burns the hair orifices, causing inflammation of the scalp, resulting in hair loss, scalp oil, and dandruff; The main color in the hair cavity, red hair and blood decay, and pigmentation decreases, resulting in white hair.

Every hair cell of a person has the power of exhalation and protection, which is presided over by the dragon (qi). Once the protective power of hair cells decreases, vomiting becomes disordered, and the dragon (qi) becomes strong, the wind becomes dry and surpasses the blood, resulting in the formation of a whole piece, gradually increasing from small to large, and even completely shedding; The secretion and protective function of the hair cavity itself undergo mutations, directly affecting its color, resulting in white hair.

Blood deficiency, insufficient bacon, unable to provide for the needs of hair, withered hair, and excessive shedding. Over time, the scalp secretion function becomes imbalanced, and the scalp and hair follicles gradually shrink.

If the dragon's (qi) movement is not smooth, the blood circulation will be unfavorable, the scalp blood circulation in the area of hair loss and white hair will be obstructed, the hair will not receive sufficient nourishment, and it will fall off due to malnutrition. The hair opening will shrink and become shallower, and the scalp will shrink accordingly, among a series of adverse reactions.
