Glabrousness

Glabrousness (from the Latin glaber meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering.

A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow.

In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials.

In humans, glabrous skin is found on the ventral portion of the fingers, palms, soles of feet and lips, which are all parts of the body most closely associated with interacting with the world around us,[3] as are the labia minora and glans penis.

[citation needed] Within entomology, the term glabrous is used to refer to those parts of an insect's body with are lacking in setae (bristles) or scales.
