Shine bright like a less dense strand of hair

What? No. Hair, clothes, stone, dirt, pretty much everything is darker when wet. It's because of energy conservation. Wet things have a stronger specular reflection, therefore less diffuse reflection. In other words, instead of reflecting incoming light in every direction, it reflects it in a narrow angle, if you're not in that angle the object seems dark.
