Is cradle cap contagious – can cradle cap be caught off someone, such as another baby?
Because the development of cradle cap is dependent on the immune system rather than the presence of a fungus, cradle cap is not contagious nor is it caused by being unclean or from poor hygiene. It is not technically an allergic reaction, either. However, it does seem to occur more frequently within families, thus further supporting the notion that a person’s particular immune system is responsible—the immune system qualities are passed on genetically.
