The main reason is that skin is alive and hair is dead. Melanin is the dark brown pigment produced by your skin to absorb some of the UV radiation from the sun.

The melanin in your hair is destroyed by sun and your hair will not produce more melanin to respond to that since it is dead. Your hair will stay lighter until new hair grows in.

Skin on the other hand is alive and when the melanin is destroyed by the sun, the skin responds by producing more melanin and thus your Skin get darker.

The sun, particularly after swimming, lightens hair by oxidizing your hair. This results in Hydrozen peroxide (a bleaching agent) to be formed on your hair and thus lightening it.

There are so many ways to naturally lighten hair. Some of them are: Honey and Cinnamon, Black tea, Chamomile juice, Baking soda etc.

The sun actually fades your hair. Both natural and artificial pigments fade with exposure to UV rays. If you are a swimmer, the chemicals in a public pool will lighten your hair. If you don't want your hair color to fade, best thing to do is wear a hat. If you like your hair color when it's lighter, I strongly suggest getting it lightened by a professional. They will keep records of what lightening process they use and replicate it each time you visit.

Hair can be bleached of color by the heat and radiation from the sun, melanin in the skin darkens to help prevent damage to it by the sun.

Since the sun is so bright, it lightens your hair. I have brown hair, and it always turns gold in the summer sun. Black hair would probably turn a little brown-ish, and blond hair would turn lighter. If you already have really light hair, you're probably okay. Red hair will turn orange. And beware of the killer freckles.

The sun naturally bleaches your hair when you may be outside for a period of time. The sun can lighten up the hair strands, much the same way as fading the colors on a shirt.
