Right, who cares? Why are you comparing yourself to models and actors?
That was to drive the point with a common reference point. The moon in this is comparing yourself with yourself. Maybe OP looks gorgeous with hair but banal without and it's frustrating him.
If shaving your hair gets you from an "8" to a "6" on a "hotness scale", that's two "points" wasted for nothing and OP may be looking at some quick win to get those two points back.
It changes your face.
Pick any good looking actor. See how they look with a shaved head vs. with hair. Even those who look good without hair, they often look better with hair. When you shave your head.
