Droplets may fall on your hair after going out, and you don’t have to worry too much about bringing the virus under the covers at night without washing your hair. Because hair belongs to non-absorbent material, droplets containing virus on hair for more than 1 hour may not be infectious. However, according to the conclusion of the study that SARS virus can survive for 2-3 days on the surface of various objects such as plastic, glass and fabric, it can be presumed that the new coronavirus may survive for 2-3 days on the hair. Therefore, for insurance purposes, it is recommended to wash your hair and shower and wash your clothes in a timely manner while making sure to wash your hands regularly after going out and coming home. If you do not want to wash your hair, it is recommended that you wear a hat when you go out and disinfect it when you get home.
