To me, most important is the quality of the hair – and that takes good treatment.  The future is about shiny healthy hair no matter what color it is, no matter what length it is.  Maybe we’ve become sidetracked because of business and trends but we need to get back to healthy hair with a good cut, and then begin again. Today’s trend of very long hair is concerning to me, because that very long hair is old hair, and sometimes it has been overprocessed to the point of being dry and unhealthy looking.  Personally, I would much prefer to see hair that is healthy and shiny with a great cut.
