You are funny , but it is true.
But those of us who cannot do it at home , there is no easy way. Even My 13 years old boy has to be dragged every time for hair cut. This weekend I had to tell him , do you want me to call the police to handcuff you and take you to hair cuttery.
For little kids the hair cutteries should have a magician or clown on call. 
Good idea.
