What actually happens
The joke is short. The answer deserves context.
Colds are caused by viruses, not damp hair. Being cold or uncomfortable might affect behavior or exposure patterns, but the villain still needs to be a virus. Your wet hair is dramatic, not infectious.
How the myth got legs
Every sticky belief has an origin story.
Parents saw cold weather, wet hair, and later illness, then connected the dots with household authority. The virus quietly accepted none of the blame.
