There is no plus side…

But there are reasons why it is still passed down.

The first is that most men go bald years and years after they have already had children and passed the gene on.

The other reason is that humans do not completely segregate bald men from men with hair when choosing a mate. So even bald men can have an attractive personality and other traits that make them a suitable mate…such as having money which is important to help provide a comfortable life for the offspring and ensure their survival.

Some male apes go bald too just like humans. It is an indication of maturity and experience. It’s kind of a way to distinguish one who is older, have experienced and survived much more, and therefore is a better leader. Although in humans, it’s probably not an evolutionary advantage, but merely a mutation since not everyone loses their hair. The genes for baldness is recessive, which means that both your parents have to have the gene for you to go bald.

It remains present because going bald(unless you bald really early) doesn’t affect your chance or ability to pass on your genes to your children. The plus side is… you can save money on hair products?
