How to disinfect hair during the epidemic

Washing your hair is the best way to disinfect it.

The purpose of washing your hair is to clean it. Combing your hair to untangle the knots will ensure that the following steps are done more thoroughly. Secondly, before applying shampoo, you should thoroughly wet your scalp and hair. This does not mean that the hair should be dripping with water, but the scalp must be completely wet. If it is not wet, the shampoo will not be able to foam evenly on all parts.

Do I need to wash my hair after going out during the epidemic?

If possible, it is best to wash your hair, especially when going in and out of crowded places. But if you really don't want to wash your hair, it is safer to wear a hat when going out.

The situation in crowded places is more complicated, and it is possible to be infected by droplets. However, according to the research conclusion that "SARS virus can survive for 2-3 days on the surfaces of various objects such as plastic, glass, mosaic, metal, cloth, copy paper, etc.", it is speculated that the new coronavirus may also survive for 2-3 days on the hair. However, because hair is a non-absorbent material, it is speculated that droplets containing the virus will not be contagious if they remain on the hair for more than 1 hour.
