Why does a redhead male have blond facial hair instead of red hair even though he shaves often?

The color of facial hair is not necessarily the same color as the hair on the top of your head and the variation in color is generally higher among gingers and blonds than among brown or black-haired individuals. The color of a man's facial hair is usually the same color as the hairs on his arms and chest. Repetitive shaving only changes the quantity of facial hairs a man possesses, not the color of said hairs.
