Frontal hair placed in wrong direction

This is a widespread error for surgeons performing a hair transplant.  Hair is often placed like the spokes of a bicycle, circularly.  In this particular man, the mistake was for half of his right hairline; however, I often see the entire hairline created this way.  When a man has straight hair, such errors create a freaky look.  See where half of the right frontal hairline points in the wrong direction. I drew straight lines in the photo to show the error.
