What is the evolutionary reason why many men lose their hair?

the reason we have hair is to protect ourselves against cold.

people who lose their hair usually lose it after 30 years old

and they can start to reproduce around 15.

This gives the people who lose their hair a LOT of time to reproduce before losing their hair, catching a cold and dieing from it.

That's why losing our hair hasn't been rejected by evolution. Not because it's better, but because it's not too bad: gives enough time to reproduce.

Natural selection doesn't select the "best" possible species... it only kills off those who can't survive long enough to give birth. But don't worry, that's a common misunderstanding

What is the evolutionary reason why many men lose their hair?

Evolution explains long term changes. Even old animals lose their hair or fur. This is primarily used it the case of animals for insulation and in many including humans for social reasons like mate selection.

Once we are past our reproductive prime, there is no sense in continuously recharging the hair.

What is the evolutionary reason why many men lose their hair?

The effect is most common in men who are well past the stone age life expectancy of 30 years. Past the point where a man would have fathered children so it couldn't have an impact on mate selection.
