The reasons for seborrheic alopecia
Lead to the essence of the reasons for seborrheic alopecia has no clear-cut theory of medicine. Western medicine is currently inclined to think that the body fat bald and on the high androgen levels. Experiment was done to prove that when the human serum testosterone concentrations of male hormones, such as 30 micrograms / L or more will inhibit the growth of hair follicle cells, the higher the concentration the stronger the inhibition. On the other hand, many studies have shown that hair loss seborrheic serum androgen concentrations compared with normal subjects did not significantly increased. Long-term research and observation that lead to hair loss Seborrheic key to the most direct reason is that excessive secretion of sebum, the skin of some components, such as oleic acid, linoleic acid, squalene, such as excessive toxic effect on the hair follicle, resulting in fur poisoning, withered, fell off. The experimental results show that these elements will contain the grease coated fur animal fur on it will cause a large number of detached. Seborrheic alopecia and excessive sebum secretion is directly linked to the evidence is that the body temperature high and low sebum secretion, and the higher the temperature the more sebum secretion. Therefore, high temperature in summer season on seborrheic alopecia particularly serious symptoms in the winter and spring will be softer, which generally have experience of patients; this point with serum level of male hormones can not be explained, in general male hormones in the body level is stable, with little relationship between high and low temperatures. Hair loss hair growth is mainly due to ecological destruction on the scalp at the same time there are too many parasites, has led to mass produce oil.
It is still unable to confirm the androgen excess is the root cause of fat bald. In addition, traditional Chinese medicine believe that hair loss is deficiency of blood by the kidneys, liver depression qi stagnation, yin deficiency caused by heat. But such a view of all the different types of hair loss classification and the lack of clear and detailed pathological analysis. Should see all the different types of causes of hair loss is not the same as it is difficult to have all attributed to kidney deficiency, especially seborrheic alopecia.
Today's medical profession generally believe that seborrheic alopecia and the following three factors:
1) androgen
Confirmed that modern medicine, seborrheic alopecia, and the male hormone are more, mainly testicular androgen secretion into the blood circulation, the arrival of the scalp into the role by the formation of toxic substances to stimulate the hair follicle, hair follicle energy metabolism and protein metabolism barriers, resulting in hair loss.
