What are the complications of hair transplant as a whole that may defame/bring disrepute to the procedure in general with catastrophic outcome?

Young surgeons falling to propaganda of companies selling their wares. There is a common misconception that some machines do all the work which is absolutely unfounded and spread by unethical companies. The complications are going to arise from a large number of FUE surgeons who are untrained and rely on these machines. It shall take another 2 years for establishing a standard of care in FUE technique.
