Glabrousness (from the Latin glaber meaning "bald", "hairless", "shaved", "smooth") is the technical term for an anatomically atypical lack of hair, down or other such covering. This may be natural or due to loss because of a physical condition, such as alopecia universalis, which causes hair to fall out or prevents its growth.
