"No hair washing"
This is easily the most debated practice in confinement. It is also the reason why many mothers reject the confinement concept.
This concept probably originated from the colder regions of China in an era where dwellings were not effective at keeping the occupants warm. However, in today's setting, where we can easily regulate water temperature, maintain warmness in the bathroom, and use hair dryers to quickly dry our hair, Chinese Medicine practitioners no longer consider this restriction to be appropriate. In fact, in the Australian context, a lack of personal cleaning will more likely be a cause of illnesses.
Simply put, this restriction has its roots but is no longer required, and is not recommended in the modern Australian context.
