Quote:this looks like a good idea, but as an old pro wearing for 20 plus years im a bit confused as to why you have mutiple measurement's from the width?

One's along the curved contour (as if you put a tape measure on your scalp). The other one is going straight across. These two numbers give you a sense of how much curvature is in your scalp.

These two measurements are shown for the width (left to right) and the length (front to back).
