Why does the sun lighten our hair, but darken our skin?

Melanin is a pigment found in your skin and hair cells that gives each its color.

It does seem weird that the sun bleaches our hair and darkens our skin. This mostly has to do with hair being dead and skin being alive.

The sun bleaches and destroys the melanin in your hair giving you lighter hair. Since hair is dead, the hair will stay that color until new hair comes in.

When sun shines on your skin, it destroys the melanin as well. But since your skin is alive, it can respond to the sun's damage. Your skin cells make more melanin and your skin becomes darker.

hair is dead and skin is alive. actually the largest organ on the human body. skin creates melanin to protect itself from uv rays. over exposure to uv light causes an over production of melanin in the skin as a defense causing darker pigmentation of the skin.

coz the sun is using the "night-vision-mode" .... lol

It's trying to be fair ...
