There are no ghosts in the world, and naturally there will be no "ghosts" who shave their heads. Then why is it called "ghost shaving"? This is nothing more than explaining the sudden and unconscious hair loss, and the patient himself does not know when it fell off. Hair loss is short and magical.
This kind of sudden hair loss without disease, pain and itching is called "alopecia areata" in medicine. In the past, there were titles such as oily wind, hair pulling, hair shedding, hair shedding and licking ghosts in ancient Chinese medicine books. The classic Chinese medicine book "Etiology" wrote: "People have wind evil in their heads. When the body is weak, it will lose hair and muscle necrosis, or it will be as big as money, or it will not be itchy, so it is called a ghost. " The "ghost head" mentioned by the ancients refers to a large area of hair loss. The place where it falls off is either the size of a copper coin or the size of a finger belly, and the affected area is neither painful nor itchy. At the same time, the ancients also knew that "ghosts" did not lick their heads, but wind evil invaded the weak human body. Once wind evil invades the head, the head is yang-deficient, leading to hair loss.
In another ancient medical book, Heart of Surgery-Oil Wind and Alopecia Areata, it is written as follows: "The hair of this disease is scorched and the skin is red and bright. It can be seen in ............................................................................................................................. that people call alopecia areata" ghost shaving "today, or it has its origin.
