Glabrous is an adjective that means smooth and hairless.

The Latin word glaber (GLOB er) means smooth and has been with us since the mid 17th century. Here’s an example of glabrous in use:

At my age I don’t really get upset about finding the occasional gray hair. I’m just happy that when I look at the top of my head, I still find hair and not a slick, glabrous surface.
