Why do bald heads shine?

The shininess of a bald head is due to the reflection of light off of the scalp. When the light hits the scalp, the light waves bounce off of the smooth surface and are reflected back to the viewer's eyes. The amount of shine will depend on the angle of the light and the shape of the head. If the light is coming from directly overhead, the entire scalp will appear shiny. However, if the light is coming from an angle, the scalp may appear shiny only in certain areas.

In addition, the amount of shine will also depend on the amount of hair on the scalp. If there is no hair at all, the scalp will appear shinier than if there is even a small amount of hair. This is because the hair will absorb some of the light waves, preventing them from being reflected back to the viewer's eyes.

Finally, the amount of shine will also depend on the texture of the skin. If the skin is smooth and oily, the scalp will appear shinier than if the skin is rough and dry. This is because the oil will help to smooth out the surface of the scalp, allowing the light waves to bounce off more easily.
