Recently, some netizens said that they experienced hair loss after being infected with the new coronavirus. Why does hair loss occur after COVID-19 infection? Is hair loss a sequelae of COVID-19 infection? How long does it take to recover? Hear what the experts have to say.
Why does hair loss occur after being infected with the new coronavirus?
Deputy Chief Physician of the Department of Dermatology, Tsinghua Chang Gung Memorial Hospital, Beijing, Tsinghua University:
It is relatively common to experience hair loss after being infected with the new coronavirus. After being infected with the new coronavirus, the first one is the virus , which may cause an inflammatory reaction around the hair follicles, and can also cause high fever. After getting the new coronavirus, it can also cause anxiety, mental stress, and poor rest. These various reasons can indeed cause telogen effluvium . What is telogen effluvium? Hair follicles have a very regular cycle. For most hair follicles, more than 90% of the hair follicles on our head are in a growing state, that is, they do not fall off. When it enters renewal, it will enter a resting period that lasts for 2 to 3 months and then fall off. After falling off, it will enter the next growth cycle.
How long will it take for the symptoms of hair loss to be relieved?
Duan Xiaohan, deputy chief physician of the Department of Dermatology, Beijing Tsinghua Chang Gung Memorial Hospital, Tsinghua University:
Most of the telogen effluvium will stop after the inducement is removed, such as when the hair follicles enter a normal state. Generally, there is no need for special clinical intervention. For example, the hair loss will stop in 2 to 3 months.
Is hair loss a sequelae of COVID-19 infection?
Duan Xiaohan, deputy chief physician of the Department of Dermatology, Beijing Tsinghua Chang Gung Memorial Hospital, Tsinghua University:
Most of the sequelae are of this kind, and we only call them sequelae if they are irreversible. For example, I developed a symptom after being infected with COVID-19 today. The inflammation can subside and the corresponding clinical symptoms will disappear. For hair, it currently seems that COVID-19 will not cause this kind of permanent hair loss. Strictly speaking, it cannot be said to be a sequelae.
How to protect your hair in daily life?
Duan Xiaohan, deputy chief physician of the Department of Dermatology, Beijing Tsinghua Chang Gung Memorial Hospital affiliated to Tsinghua University:
The special suggestion is to pay attention to the intake of protein . In terms of diet, I always recommend eating more meat. Among meat, I prefer beef, because beef is rich in iron. The synthesis of hair cells, the synthesis of DNA, these growth cycles require trace elements, such as vitamin D, deep-sea fish, cod liver oil, cod, and salmon, which are actually foods rich in vitamin D. If you care about your hair and are afraid of hair loss, I don’t recommend losing weight very quickly. If you lose weight very quickly, your energy will be lost all of a sudden, and hair loss will occur.
