One of the misconceptions, hair loss is caused by kidney deficiency. Many male patients often think that hair loss is the fault of kidney deficiency, for those patients with severe hair loss are desperately trying to spend money to buy some kidney supplements. Kidney deficiency causes hair loss, is a kind of Chinese medicine identification, but hair loss is not all kidney deficiency, a taste of tonic actually does not help much. Myth No. 2, blindly reduce or increase the number of shampooing. Some patients believe that the scalp oil secretion, resulting in excessive oil, thus increasing the number of times to wash hair. General winter 3-4 days shampoo once, summer 2-3 days shampoo once is the normal frequency of hair washing, too often will increase the stimulation of hair follicles, too long is easy to breed furfur spores, hair loss aggravated. The third misconception is that you buy your own medicine to cure yourself. Patients to figure out the convenience of gullible advertising, buy drugs to eat. However, the medicine is not the right one, can not eliminate the cause of the disease, can not play a therapeutic role, but delayed the treatment time, so that hair loss further deepened. Patients should go to the hospital to diagnose the cause of the disease, and then use the medicine under the guidance of a doctor.
