Some men grow their hair long in order to cover their bald spots. Is there a word for this?

Yes, there is — `combover’. It’s called a combover because what these men usually do is to allow the hair on one side of their head to grow long and then they proceed to comb it over the top of their head to hide their baldness. The billionaire Donald Trump, the man you see in the series “The Apprentice”, has a combover.
